Adapt to the maintenance and reliability of harsh environmental conditions: In harsh environmental conditions, such as coal mines, the automatic refueling system can ensure the cleanliness of the hydraulic fluid and reduce the failure caused by pollution, thus improving the maintenance and reliability of construction equipment.   6. The application of a centralized fluid supply system: the application of an oil centralized filling system in construction machinery demonstrates the characteristics and advantages of a centralized fluid supply system, which can achieve more efficient and economical hydraulic oil management for large construction machinery such as excavators.   The application of automatic oilers in excavator hydraulic systems has brought significant benefits, including improved work efficiency, reduced work intensity, enhanced anti-pollution capabilities, time savings, improved refueling efficiency, real-time monitoring of hydraulic fluid status, and adaptation to maintenance and reliability under harsh environmental conditions. These advantages make the automatic oiler an indispensable part of the excavator hydraulic system.       What Are The Filtration And Purification Methods For Excavator Hydraulic Oil And How Effective Are They? Excavator hydraulic oil filtration and purification methods mainly include the following, and their effects are different: 1. Three-stage cartridge filtration system: This system through the design of a three-stage cartridge filter and pipeline filtration system, the use of quick-change couplings will be connected to the filtration system and the hydraulic oil tank of the construction machinery, to meet the needs of high-volume construction machinery hydraulic oil filtration operations. This method can effectively reduce the pollution level of hydraulic oil, which is better than the industry standard.   2. High-precision cartridge filtration technology:  This technology usually refers to the size of the particles that can be filtered out below 3μm pollutants of the oil filter, the cartridge properties are mainly mesh, paper, sintered, steel wire and magnetic and other forms of filtration accuracy of up to 1μm. this method can effectively remove small particles of pollutants in the hydraulic oil, and improve the cleanliness of the hydraulic system.   3. Electric heating + multi-stage filtration + oil and gas separation: First through the electric heating system to heat the oil temperature to 60 ° C, and then sequentially primary filtration (using a new type of high-gradient electromagnetic cartridge in parallel to filter the oil ferromagnetic corrosion products and oxidation of macromolecules), intermediate filtration (to remove large solid particles), three-stage filtration (using a high filtration accuracy of the ordinary parallel filter cartridge to form a redundancy), and finally by the An exhaust valve removes gaseous impurities from the oil and air bubbles generated during the filtration process, and removes water from the oil through an oil-water separation system. In addition, the oil cleanliness level is monitored in real-time by a pollution particle counter, and the solenoid valve of the oil return pipe is closed when the purification level requirement is reached.   4. Centrifugal separator: A hydraulic oil purifier is designed, which consists of a pretreatment oil circuit and a centrifugal separator, and can gradually and effectively remove water, air, and solid particles from the hydraulic oil, to ensure the good operation of hydraulic machinery.   5. Hydraulic tank cleanliness control: Through the hydraulic tank manufacturing process improvement, including tank structure and manufacturing process improvement, as well as the development of new tank pre-treatment, drying, and dust-free assembly methods, you can effectively avoid the adverse effects of solid particles on the service life of the hydraulic system to achieve the purpose of improving the cleanliness of the hydraulic system.   Each of these methods has its characteristics, but the common goal is to reduce the contaminants in the hydraulic fluid through various technical means to ensure the normal operation of the hydraulic system and extend its service life. Each method has its unique advantages and applicable scenarios, and choosing the right filtration and purification method is crucial to improving the performance and reliability of the excavator hydraulic system.       What Are The Best Practices For Replacing Excavator Hydraulic Oil Filter Elements? Best practices for replacing excavator hydraulic oil cartridges involve several aspects, including hydraulic system oil change methods and procedures, hydraulic tank design, hydraulic filter selection and use, and the proper selection of hydraulic filters. The following is a detailed analysis based on the information I searched for:   1. Hydraulic system oil change methods and steps: first of all, you need to understand the excavator hydraulic system oil change methods and steps, which is the key to avoiding system contamination. The oil change process should pay attention to matters including ensuring the quality of the new oil, the use of the correct tools and techniques for the operation, as well as after the oil change to carry out appropriate checks to ensure that the system operates normally.   2. Hydraulic Tank Design: The design of the hydraulic tank is critical to preventing air bubble problems and cartridge dislodgement. Therefore, when replacing the filter element, the return filter structure of the hydraulic tank should be considered to ensure that it can effectively filter the impurities in the fluid, thereby reducing the occurrence of failures.   3. Hydraulic filter selection and use: The reasonable selection and use of hydraulic filters to ensure the normal operation of the excavator hydraulic system is an important part. Should be based on the actual application of construction machinery needs, choosing the most appropriate hydraulic filter specifications, to give full play to its functional role.   4. Reasonable choice of hydraulic filter: in the hydraulic system, the choice of oil filter should follow the general principles and methods. This includes consideration of the specific working conditions of the system, the expected working life, and the required filtration accuracy and other factors. Reasonable oil filter selection can significantly improve the stability and reliability of the system.   5. Hydraulic oil filter selection: in the design and improvement of hydraulic systems, how to rationally select and effectively use the oil filter is an important discussion point. This involves an in-depth understanding of the performance of the oil filter, including its filtration efficiency, durability, and compatibility with other components of the system.   Best practices for replacing hydraulic oil filter elements in excavators should include the following key steps: first, understand in detail and follow the hydraulic system's oil change methods and procedures; second, consider the characteristics of the hydraulic tank design to ensure that the filter element can work efficiently; third, reasonably select hydraulic filters based on actual application needs; and finally, reasonably select and use filters based on the hydraulic system's operating conditions and requirements. Through these steps, you can ensure the efficient and stable operation of the excavator hydraulic system.       How To Adjust The Maintenance And Repair Strategy Of The Excavator Hydraulic System According To Environmental Factors? The first thing to consider when adjusting the maintenance and repair strategy of an excavator hydraulic system according to environmental factors is the special requirements in a high-altitude environment. At high altitudes, due to the lower air pressure, the ambient temperature is also relatively low, which directly affects the working efficiency and reliability of the excavator hydraulic system. To adapt to this environment, it is necessary to match the power of the engine and the main pump and adjust the air volume and static pressure of the fan and radiator. In addition, it is also necessary to take measures to pressurize the hydraulic oil tank, adjust the speed and displacement to prevent the main pump from sucking empty, and adjust the hydraulic oil viscosity level in time according to the ambient temperature at high altitudes to protect the hydraulic components and reduce the starting torque.   Considering the energy consumption of the excavator under different working conditions, the potential energy loss of the movable arm in the descending process can be recovered and used for its next ascending action, which can effectively reduce the energy loss and improve energy utilization efficiency. This method not only helps to save energy but also extends the service life of the equipment and reduces maintenance costs.   In terms of maintenance strategy, a more scientific and reasonable maintenance plan can be developed for key components such as hydraulic cylinders based on reliability analysis and failure mode and effect analysis (FMEA). By collecting historical failure data and utilizing statistical tools and parameter estimation methods, reliability parameters are determined so that appropriate maintenance policies and countermeasures can be formulated for new hydraulic cylinders.   In addition, controlling the degree of contamination of the hydraulic system is also a part of maintenance that cannot be ignored. Studies have shown that a significant portion of the hydraulic system failure is due to improper use of hydraulic oil, and a large portion of these failures is due to foreign matter mixed in the oil. Therefore, controlling the generation of pollutants, reducing residual pollutants and the correct selection and rational use of oil filters is the key link to control the degree of pollution.   Adjusting the maintenance and repair strategy of the excavator hydraulic system according to environmental factors requires comprehensive consideration of the special requirements of a high-altitude environment, improvement of energy utilization efficiency, maintenance strategy development based on reliability analysis, and effective control of contamination and other aspects. Through scientific and reasonable design and maintenance measures, the performance and reliability of the excavator hydraulic system can be significantly improved, the service life of the equipment can be extended, and maintenance costs can be reduced.        

In the construction machinery industry, loaders play an indispensable role in numerous construction projects, from material handling to excavation. In this blog, the LTMG team will delve into the three primary types of loaders commonly found in the construction industry.   1. Wheel Loaders: Wheel loaders are primarily used for loading and short-distance transportation of loose materials. They are typically composed of an engine, transmission system, travel mechanism, hydraulic system, and operator's cab. Wheel loaders are characterized by their strong mobility and large loading capacity, allowing them to quickly complete various loading and unloading operations. Additionally, wheel loaders excel in productivity, fuel efficiency, and operator comfort.     2. Backhoe Loaders: Backhoe loaders are equipment that combines excavation and loading functions. They can be equipped with attachments such as boom arms, forks, sweepers, breakers, and vibratory compactors. Their design allows them to work efficiently in narrow spaces, such as urban infrastructure, roads, or construction sites. Backhoe loaders can reach speeds of up to 40 km/h and are equipped with a 4 or 5-speed hydrostatic transmission.     3. Skid Steer Loaders: The most significant feature of skid steer loaders is their compact size and ability to turn in place, making them particularly suitable for operation in confined spaces such as urban infrastructure, roads, construction sites, and factory workshops. They steer by varying the speed of the wheels on each side of the vehicle. Skid steer loaders can also quickly change or attach various work devices to adapt to different work environments.     In summary, wheel loaders are suitable for situations requiring large loads and long distances; backhoe loaders are more suitable for small projects requiring both excavation and loading operations simultaneously; while skid steer loaders, due to their compact and agile nature, are ideal for use in confined spaces. Each type of loader has its specific applications and advantages, and choosing the right model can greatly improve work efficiency and safety.     What are the differences in operational safety among different types of loaders? The main differences in operational safety among different types of loaders are reflected in the specific requirements for operators, pre-operation preparation, operational precautions, and operational restrictions in specific environments.   1. Operator requirements: All types of loader operators must undergo physical examinations and specialized technical training, understand mechanical performance, structure, and maintenance procedures, be familiar with operation methods, and hold a driver's license after passing the exam before they can operate independently. This indicates that the basic requirements for operators are uniform, but the specific operating procedures for different types may vary, such as wheel loaders also need to comply with relevant regulations of the transportation department.   2. Pre-operation preparation: Regardless of the type of loader, a series of preparatory work is required before the operation, such as checking the engine oil, water (including battery water), fuel, hydraulic oil, whether the control levers are in a neutral position; hydraulic lines, brake lines, and joints are loose or leaking. These preparatory work are crucial for ensuring operational safety, but the specific inspection items may vary depending on the type of loader and the different working environments.   3. Operational precautions: During operation, the operation of the loader needs to follow a series of safety operation regulations, such as sounding the horn first, observing that there are no people or obstacles in front, back, left, or right before the operation, strictly prohibiting people under the bucket, and prohibiting loading people in the bucket, etc. In addition, inappropriate high speed and sharp turns should be avoided, and when encountering increased resistance, tire slippage, and decreased engine speed, loading should be stopped, and forced operation should not be carried out. Although these precautions apply to all types of loaders, in actual operation, different types of loaders may have different requirements and restrictions when performing these operations due to their different structures and functions.   4. Operational restrictions in specific environments: Some types of loaders may have specific requirements for the operating environment, such as not being suitable for operation in areas with high dry dust and wet clay. These environmental restrictions directly affect the operational safety of the loader, and different types of loaders may have differences in adapting to specific environments due to their different designs and performances.   The differences in operational safety among different types of loaders are mainly reflected in the specific requirements for operators, pre-operation preparation, operational precautions, and operational restrictions in specific environments. Although the basic principles of safe operation are the same, due to the different types of loaders and working environments, the specific implementation details and requirements may vary.     What is the cost-effectiveness comparison of wheel loaders, backhoe loaders, and skid steer loaders? Wheel loaders, backhoe loaders, and skid steer loaders each have their characteristics in terms of cost-effectiveness. Wheel loaders gain advantages with their lower hourly costs and higher transport efficiency, for example, the Cat® 988 GC wheel loader can significantly save fuel, reducing owning and operating costs by up to 10%. Liebherr L566 and L550 wheel loaders also emphasize their cost-effectiveness and environmental friendliness, consuming only 40% and 25% of the fuel under the same working conditions, respectively. These data indicate that wheel loaders can effectively reduce operating costs in long-term operation.   Backhoe loaders may be more cost-effective than wheel loaders in certain situations, especially in scenarios that require quick switching between work modes. Backhoe loaders have high maneuverability and versatility, allowing them to be used flexibly in different job sites. One machine can perform multiple tasks, saving the cost of purchasing multiple types of machinery and reducing the workload of maintenance and management.     On the other hand, although skid steer loaders may save labor costs in some cases, such as the LiuGong CLG385B skid steer loader saving users at least 1 million yuan in labor costs per year, its purchase price and operating costs are higher. In addition, skid steer loaders are not as efficient as ordinary wheel loaders and other specialized equipment in loading, milling, and snow removal efficiency. From the analysis of the cost-effectiveness of wheel loaders, backhoe loaders, and skid steer loaders, users should choose the most suitable model based on their specific needs and conditions.     Choose the Right Construction Machinery Equipment for You Even for experienced owners and operators, understanding the subtle differences of modern construction machinery can be challenging.

(2) In contrast, other types of loaders, such as track loaders, although also possessing good maneuverability, may not be as flexible and passable as articulated wheel loaders under certain operating conditions.   2. Application Scenarios: (1) Articulated wheel loaders are suitable for a wide range of complex terrains and environments due to their excellent passability and maneuverability. For example, the XCMG WZ30-25B backhoe loader integrates digging and loading and can be equipped with a variety of attachments, which are suitable for several operations such as digging, shoveling, transporting, and leveling the site. (2) Other types of loaders, such as the Komatsu WA380-6 loader, are designed for specific light-duty operations, such as shoveling and loading of loose materials and short-distance transportation, and are suitable for scenarios such as highways, railroads, and ports.   3. Technology and Innovation: (1) The articulated wheel loaders are constantly innovating in terms of technology. For example, the Cat® 966 GC wheel loader adopts an advanced hydraulic system and control device, which can significantly improve the full bucket factor and reduce fuel consumption. (2) Other types of loaders are also pursuing development in the direction of high efficiency, energy saving, and emission reduction, for example, the Shandong Lingong L968HEV wheel loader adopts dual-way braking energy recovery technology, which improves energy efficiency and range. To summarize, articulated wheel loaders show high flexibility and adaptability in performance, especially in complex terrain and the need for frequent changes in the operating environment is more prominent. Other types of loaders show their specialized strengths in specific areas of operation (e.g. light material handling).     What are the market shares and major manufacturers of articulated wheel loaders?

The rainy season poses a significant challenge to heavy equipment like excavators. Continuous rainfall and humid environments not only affect the excavator's operational efficiency but can also lead to severe mechanical damage. This article provides detailed instructions on how to protect and maintain your excavator during the rainy season to ensure it operates efficiently and safely.   1. Safe Parking Location Elevated Parking After completing work in the rainy season, the excavator should be parked in a high and firm location. This measure can effectively prevent the equipment from being damaged by landslides, mudslides, or flooding. Avoid low-lying areas and regions prone to landslides when choosing a parking spot to ensure the equipment is in a safe location.   Comprehensive Shutdown After parking, ensure all doors and windows of the excavator are tightly closed to prevent rainwater from entering. Cut off the main power supply of the machine and check if the fuel tank and hydraulic oil tank caps are tightly sealed. Even if the water recedes, do not start the excavator immediately. First, hoist the equipment to a safe location for cleaning, then conduct thorough inspections and repairs of all systems.     2. Engine Section Inspection Removing the Air Filter First, check if the intake system has water. If there is water in the cylinder, disassemble the engine for thorough cleaning. Do not use the method of rotating the crankshaft to expel water from the cylinder liner through the injector hole, as this can damage the cylinder liner components.   Oil Inspection Check the oil dipstick to see if the oil level has increased and whether the oil contains mud and water. The best approach is to disassemble the entire engine for repair. If this is not possible, perform partial disassembly and cleaning on the machine. After cleaning, replace the engine oil, oil filter, and other maintenance items with new ones to ensure normal engine operation.   Fuel Tank Inspection If the fuel tank has water, first drain the water from the bottom of the tank. Let the diesel in the tank settle, then use it for cleaning. Wash the tank with water under certain pressure, wipe it clean with a cloth, especially the partitions and corners inside the tank. Finally, rinse the tank with diesel. Disassemble and clean the low-pressure and return lines from the tank to the fuel pump, and dry them with compressed air.   3. Hydraulic System and Transmission Components Cleaning the Hydraulic System The hydraulic oil tank is usually sealed. If mud and water get in, drain the oil and water from the tank, thoroughly clean the tank and pipelines, add new hydraulic oil, and replace the filter.   Inspecting the Hydraulic Pump Loosen the drain screw on the hydraulic pump and check if the drained oil contains water. If there is no water, inspect the control valves and other components (including the hydraulic oil cooler). If no water is found, the main pump, high-pressure oil circuit, and working devices are considered normal.   4. Electrical Components and Circuits Cleaning Electrical Equipment Remove the starter, generator, and instrument panel from the excavator. Clean them with diesel and dry them thoroughly. Check the entire electrical circuit and connections for rust or damage. Grind off the rust or replace the relevant parts if necessary.   Startup Check After cleaning and inspection, start the machine to test for any alarms. Test all working devices of the excavator to ensure they operate normally.     5. Routine Maintenance and Protection Regular Inspections and Maintenance During the rainy season, regular inspection and maintenance of the excavator are crucial. After each day's work, check for water ingress and damage in all parts of the equipment and perform timely maintenance.   Protective Measures To prevent rainwater from eroding the excavator, consider building a shelter or using waterproof covers when parking. Minimize operations during heavy rain. If necessary, add extra protective measures during operations, such as waterproof cloths and mudguards.   Operational Precautions When operating an excavator in the rainy season, the operator should pay special attention to the machine's operating status. Avoid prolonged work in deep water or muddy areas to prevent the equipment from getting stuck or waterlogged. Continuously monitor the equipment's indicators during operation and stop immediately for inspection if any abnormalities are detected.   Water Damage Handling If the excavator is submerged, do not start the machine or turn on the main power switch. Hoist the equipment to a safe location, thoroughly clean all parts, and then inspect and repair. Ensure that electrical equipment and hydraulic systems are completely dry and free of water before restarting.   As your trusted excavator OEM partner, LTMG offers reliable technical advice and professional assistance to help you maintain your equipment, even in challenging conditions.

Excavator is a kind of heavy construction machinery, which is mainly used for digging, moving and loading materials such as soil and rock. It drives the bucket and arm through the hydraulic system to realize the excavation and handling of materials. The working principle is to provide power through the engine, drive the hydraulic pump to produce high-pressure oil, and then control the bucket and arm expansion and rotation, to complete the excavation operation. In daily operation, excavator users often encounter the problem of slow bucket movement, whether it is a single movement or a combination of operations, it may appear to be incompetent.     To address this challenge, the LTMG Team offers valuable insights and methods to help you accurately diagnose the problem and implement timely and effective solutions, ensuring your equipment remains in optimal condition and enhances operational efficiency.   Inspection process for slow bucket action: First, operate the other actuators to determine if the problem is limited to the bucket, if the problem is limited to the bucket, check that the diesel engine is running at rated speed and operate the pilot valve to overflow the bucket large chamber.   Bucket large chamber merge check: Check for oil flow by touching both high pressure fuel lines to determine if the bucket large chambers are merged.       Possible causes and solutions: Bucket Large Chamber Secondary Relief Valve Problem: Check and adjust the relief pressure value, replace the spring or remove foreign material between the spool and spool seat if necessary. Bucket cylinder piston seal is damaged: replace the piston seal. Piston rod bent: correct, repair or replace the piston rod. Valve group oil outlet pipe without oil flu: check whether the valve stem is bonded or stuck by foreign matter, whether the pilot control oil pressure is too low, or whether the pilot control pipeline is blocked by foreign matter. Valve group II oil outlet pipe no oil flu: check whether the pilot pipe joint is loose, and whether the multi-way reversing valve stem has pilot reversing pressure.   Daily maintenance and care: Avoid using violent operation, especially when encountering hard objects, to prevent damage to the cylinder. Regular inspection and maintenance, especially for oil seals and other consumable parts, should be replaced in time to avoid failure.     Additional suggestions: ① Regularly check the cleanliness and oil level of the hydraulic oil to ensure that the hydraulic system works properly. ② Check the viscosity of the hydraulic oil, because changes in oil temperature will affect the viscosity of the oil, which in turn affects the performance of the hydraulic system. ③ Change the hydraulic oil and oil filter regularly to minimize wear and contamination in the system.     By following these inspection procedures and maintenance recommendations, you can effectively diagnose and solve the problem of slow bucket action in the hydraulic system of your excavator, thus improving efficiency and prolonging the service life of your equipment.   LTMG has been manufacturing excavators for more than 23 years, and we have the top after-sales service in the industry, so that you can feel the professional service and at the same time, you can also know the LTMG products' Quality Assurance.
