Which one is used for forklift maintenance in Jiading? Is there a company that does forklift mainten

Forklifts are mechanical equipment, and there will definitely be some faults. We know that there are actually many kinds of forklift failures, and today we want to introduce to you one of the more common faults - lifting weakness.

What are the specific manifestations of the lifting power of forklifts? If the forklift is working normally, the tilting function is normal, and when the cargo is lifted, it can be judged that the forklift is weak and unable to lift the fault, and how we should troubleshoot the fault is to pay special attention to at this time.

If the forklift is running normally, the power system is normal, the tilting cylinder is normal, the hydraulic pump is fine, and the lifting force is weak, the multi-way valve leakage should be considered, because the multi-way valve leakage will cause the hydraulic oil pressure of the lifting cylinder to be insufficient. The main reason for the internal leakage of the multi-way valve is mainly due to the fact that the goods are too heavy, and the driver increases the counterweight of the forklift by increasing the iron, resulting in excessive hydraulic oil pressure of the multi-way valve and damage to the pores of the oil circuit, resulting in the internal leakage of the multi-way valve.

When using forklifts, we must carry goods according to the rated carrying capacity of forklifts, overload operations will cause damage to forklifts, long-term overload operations will greatly reduce the service life of forklifts, and will also cause an increase in the cost of forklifts, causing greater losses to themselves or the company.

Excessive leakage in the cylinder Replace the piston ring or cylinder.

The pressure of the relief valve is low: Loosen the back mother and tighten the adjusting screw to increase the pressure.

Seat seal ring is damaged Replace the hoist valve block.

Oil pump leakage Replace the oil pump.

Please make sure there are no problems with the above.

Just a suggestion!!

Safety precautions. 1. Stability of forklifts.

The stability of the forklift is to maintain the balance of front and rear weight by using the front tire as a fulcrum. The position of the center of gravity of the vehicle and the loaded goods is also an important factor in determining the stability of the forklift.

2. The center of gravity of the cargo.

For various shapes of loads, it is important to know the position of the center of gravity.

3. The relationship between the center of gravity and stability.

Regarding the stability of the forklift, the center of gravity when unloaded is at the center of gravity of the forklift itself, and the center of gravity after loading the goods is determined by the combined center of gravity of the forklift and the cargo. If the mast is tilted back and forth, the center of gravity of the composite will also be shifted back and forth.

The mast is raised and lowered, and the synthetic center of gravity is also moved up and down. The center of gravity and stability when loading cargo are closely related to the following main reasons.

1) The size, weight, shape and position of the loaded goods;

2) the lifting height of the goods;

3) Forward and backward tilt angle;

4) Tire pressure;

5) Acceleration, stopping, and turning;

6) The road surface does not leak the positive shape and inclination. These main reasons must also be taken into account when unloaded. Compared to the state when the cargo is down when the load is empty, it is easier to drive left and right when the load is empty.
