The crane of the truck crane is an extremely important part of the entire vehicle. The crane will affect the lifting performance of the truck crane. Therefore, when selecting a truck-mounted crane, it is a major precondition for selecting the tonnage of the crane. 1. When selecting the tonnage of the crane that is to be lifted with the vehicle, it is necessary to have a very clear requirement. The largest crane lifting tonnage is the tonnage used when the broken arm is the shortest and the working range is relatively small. The longer the boom of the crane is extended, the greater the range of work will be, the weight of the crane will drop directly into a geometric multiple. For example, when the crane boom of the crane is outstretched to 5.6M, then its working range will reach to 2.1M, and its lifting capacity will be 1000KG, but when the truck crane When the arm reaches out to 5.6M and its working range reaches 5.4 meters, the lifting capacity of the crane will be only 400KG. 2. When selecting the crane that comes with the crane, it is also necessary to note that the crane lifting crane is the best lifting tonnage. The maximum lifting mass is 70 to 90 percent before, so When we choose to hang the crane with the car, when we choose to lift the weight, we need to have a certain degree of surplus, so that it will help increase the service life of the crane. 3. When the crane is in operation, it is necessary to notice that the elevation angle of the boom of the crane is not lower than 40 degrees. If the angle of the lifting angle of the boom becomes very low, then the boom The weight received will become very large. This will damage the boom attached to the crane. In severe cases, the boom will be broken. concrete pump,High Quality concrete pump,concrete pump Details Botou Honghai Pump Co.,Ltd , https://www.gearpump.nl
