Maintenance of wheeled excavators

Maintenance of wheeled excavators
Every morning, the entire car is filled with butter, the fuel tank is drained, the drain is drained, the oil is checked, and the coolant is checked. The premature wear of the machine's fuel system (oil pump, nozzle) is mainly caused by improper daily maintenance by the operator;
Can provide blow air filters and radiators; Complete the maintenance cycle of the machine on time and in batches. If the working environment is harsh (long-term circuit breaker operation, dusty environment), it is necessary to shorten the maintenance cycle.
Imported machines have been well maintained, and it is actually a very easy task to maintain the engine for 10000 hours without major repairs and prevent oil leakage from pumps and valves. It is necessary for the operator to take off their shoes on the vehicle.
On the one hand, dirty cabs can easily cause air conditioning filters, and dusty air circulation can also harm the body.
Introduction to using tire excavator
1. Slope leveling operation
When performing flat trimming, the machine should be placed on the ground to prevent body shaking. In order to grasp the coordination of boom and boom movements, controlling the speed of both is crucial for surface finishing.
2. Loading operations
The body should be in a horizontal and stable position, otherwise it is difficult to accurately control the rotation and unloading, thereby prolonging the cycle time; Maintain an appropriate distance between the vehicle body and the truck to prevent the rear of the vehicle from colliding with the truck during a 180 degree turn; Wide field of vision, high work efficiency, correct control of rotation angle to reduce turning time; The truck is positioned lower than the excavator, reducing the boom lifting time and providing good visibility; Firstly, install sand and gravel, and then place large stones to reduce the impact on the car.

3. Soft zone or water operation
When working in soft soil areas, it is important to understand the compactness of the soil, limit the excavation range of the bucket, and prevent accidents such as landslides and mountain landslides, as well as deep settlement of the vehicle body. When working in water, pay attention to the allowable water depth range of the vehicle body (the water surface should be lower than the center of the bearing roller); If the water level is high, the internal lubrication of the slewing bearing will be poor due to water ingress, and the engine fan blades will be folded by water. Due to water intrusion, the loss of circuit components can cause short circuits or damage.
4. Lifting operations
When hydraulic excavators are used for lifting operations, the surrounding environment of the lifting site should be confirmed, and high-strength hooks and wire ropes should be used. When lifting, special lifting equipment should be used as much as possible; The operation mode should be selected in micro operation mode and the movement should be slowly balanced; Appropriate length and length, too long will cause the lifting object to swing more, making it difficult to accurately control; The position of the bucket should be adjusted correctly to prevent the steel wire rope from slipping; Construction personnel should try not to approach lifting objects as much as possible to prevent danger caused by improper operation.
5. Smooth operation method
When working, the stability of the machine not only improves work efficiency and extends its lifespan, but also ensures safe operation (placing the machine on a flat surface).
