With the continuous development of the construction machinery market, second-hand excavators have become an important choice for many construction companies and individual users to purchase equipment. Among them, Liugong brand front loaders are favored for their stable performance and good reputation. This article will introduce in depth how to use second-hand excavators efficiently and safely from three aspects: the operating guide, maintenance recommendations and procurement channels of Liugong front loaders, and provide you with authoritative second-hand excavator supplier information.
Liugong front loader is a multi-functional construction machinery, mainly used for loading, excavation, handling and other work. Mastering the correct operation method will help extend the life of the equipment and improve work efficiency.
Fuel and hydraulic oil inspection: Make sure that the fuel is sufficient and the hydraulic oil reaches the specified oil level. The quality of hydraulic oil directly affects the power transmission and control sensitivity of the machine.
Inspection of engine compartment and mechanical components: Check whether there is oil leakage, loose connections and abnormal sounds in the engine compartment. Confirm that the cooling system is operating normally to avoid overheating.
Tire and Brake System Inspection: Front loader tires should maintain proper air pressure, and the brake system should be sensitive and leak-free to ensure safe operation.
Starting Procedure: Turn on the ignition and wait for the instrument panel self-check to complete before starting the vehicle. Avoid sudden acceleration during starting and keep the engine running steadily.
Driving Tips: Avoid sudden acceleration and sharp turns, especially on soft surfaces. When using a front loader bucket, operate smoothly to avoid sudden drops or impacts.
Loading Techniques: Keep the bottom of the bucket flat on the ground during loading and gradually load the material into the bucket to avoid overloading. When unloading, select an appropriate height to prevent material splashing.
Safety Precautions During Operation
Wearing Safety Equipment: Operators should wear a hard hat, reflective vest, and safety shoes to ensure personal safety.
Ambient Alertness: Before operating, confirm that the surrounding area is clear of obstacles and people to avoid accidents caused by blind spots.
Emergency Response Skills: Master emergency stop and troubleshooting methods to ensure the safety of equipment and personnel in emergencies.
Regular and scientific maintenance is the key to ensuring the stable performance and extended service life of second-hand excavators. For Liugong front loaders, maintenance work should include daily maintenance, periodic inspections and parts replacement.
Replacement and inspection of lubricating oil: Replace engine oil and hydraulic oil according to the manufacturer's specified cycle to keep the lubrication system clean and prevent wear of mechanical parts.
Cleaning and replacement of filters: The air filter and fuel filter should be cleaned regularly to ensure that the intake system is unobstructed and prevent impurities from entering the engine.
Hydraulic system maintenance: Check whether the hydraulic pipeline has leaks, replace aging hoses and seals in time to prevent hydraulic pressure from dropping.
Engine performance detection: Use professional equipment to detect engine power and emissions, and deal with abnormalities in time.
Chassis and steering system inspection: Check the wear of the axle, suspension system and steering system, and adjust and replace parts in time.
Electrical system maintenance: Confirm the battery power and wiring status to prevent startup failure due to electrical failure.
Fault type | Possible cause | Solution |
Engine start difficulty | Low battery or loose circuit | Charge or replace battery, check circuit connection |
Hydraulic system oil leakage | Hydraulic pipeline aging or seal damage | Replace hoses and seals, repair leaks |
Slow operation | Poor lubrication or filter blockage | Replace lubricating oil, clean or replace filter |
Insufficient tire pressure | Leak or damage | Timely inflate or replace tires |
