Maintenance of wheeled excavators
Every morning, the entire vehicle is filled with grease, the fuel tank is emptied, the drainer is drained, the oil is checked and the coolant is checked. Premature wear of the machine’s fuel system (pump, nozzles) is mainly due to poor maintenance routines by the operator;
Blown air filters and radiators are available; complete the machine maintenance intervals on time and in bulk. If the working environment is harsh (long-term circuit breaker operation, dusty environment), shorter maintenance intervals are required.
When imported machines are well maintained, 10,000 hours of engine maintenance without overhaul, pumps, and valves without oil seepage is actually a very easy task. It is necessary for the mechanic to get into the car and take off his shoes to work.
On the one hand, a dirty cab can easily cause air conditioning filters, while dusty air circulation can also harm the body.
Tips for using tire excavators
1. Slope leveling operations
When carrying out level trimming, the machine should be placed on the ground to prevent body shaking. In order to master the coordination of boom and spreader movements, controlling the speed of both is essential for plane trimming.
2. Loading operations
The body should be in a horizontal and stable position, otherwise, the rotating unloading is difficult to control precisely, thus prolonging the cycle time; the body and the truck should be kept at a proper distance to prevent the rear of the body from colliding with the truck during a 180-degree turn; with a wide view and high efficiency, the rotation angle should be correctly mastered to reduce the turning time; the truck is positioned lower than the excavator to shorten the rising time of the moving arm and have a good line of sight; first install sand, the gravel and again place large stones to reduce the impact on the car.
3. Soft areas or water running
When working in soft soil areas, be aware of the compactness of the soil and pay attention to limiting the digging range of the bucket to prevent accidents such as landslides, landslides, and deep settling of the vehicle body. When working in water, be aware of the range of water depths allowed in the body (the water surface should be below the center of the load roller); if the water level is high, lubrication inside the slewing ring will be poor due to water ingress and the engine fan blades will be folded by water. Loss of circuit components due to water intrusion will short circuit or damage.
4. Lifting operations
When hydraulic excavators are used for lifting operations, the surroundings 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 whenever possible; the operating mode should be selected in micro-operation mode with slow balancing movement; appropriate length and length too long will make the lifting object swing more and difficult to control accurately; the bucket position should be adjusted correctly to prevent the wire rope from slipping off; construction personnel should try not to get close to the lifting object to prevent the danger caused by improper operation.
5. Smooth running method
When working, the stability of the machine not only improves the efficiency and extends the life of the machine, but also ensures safe operation (placing the machine on a flat surface).
