Proper use of truck crane

Proper use of truck crane

The operation of the truck-mounted crane is different from other vehicles, because the truck-mounted crane is equipped with a crane, and there is a danger of overturning if it is inadvertent.

The following points must be noticed in the operation of the truck crane:
1. To understand the size of the cargo, find the distance from the center of the cargo to the center of the column of the crane, and learn to check the lifting capacity parameters of the crane according to the distance.
2. Know that the moment of the crane is fixed. The larger the radius of the crane, the lighter the cargo that can be lifted, and the smaller the working radius, the heavier the cargo that can be lifted.
3. Considering the lifting capacity of the crane and the bearing capacity of the chassis, the load capacity of the large beam is strong, the crane and the chassis must be matched, the chassis is small, the crane is large, and the chassis beam is easily broken; , It will cause waste.

Let‘s briefly understand the solutions to some small problems with the crane:
1. Why does the temperature of the hydraulic oil rise during the operation of the truck crane?
Reason: Insufficient hydraulic oil quantity or hydraulic oil pollution. Insufficient oil quantity may be oil leakage or defective design of the crane. Hydraulic oil pollution generally refers to the pollution of oil oxides, which will cause cooling system and filtration Blockage of the device will eventually cause the oil temperature to rise.
2. The color of hydraulic oil: The color of the hydraulic oil that has been used for a long time is darkened due to the formation of pigments. This is normal. Because the pigment is soluble in oil, it will not affect the quality of the hydraulic oil, so we cannot rely on the Color to judge good or bad.
3. The service life of the lubricating oil. The service life of the lubricating oil is affected by air, heat, impurities, and water. However, when the lubricating oil is completely purified and the temperature is below 60 degrees Celsius, the change is small. Can be added as appropriate.

During the normal use of the truck-mounted crane, it is necessary to pay attention to daily maintenance, so that the probability of failure during operation will be greatly reduced, and the work efficiency will be greatly improved.
