Precautions for operation of truck cranes

1: Understand the size of the lifting cargo, find the center of the goods to the center of the crane column distance, according to the distance to view the crane lifting capacity parameters.
2: The lifting capacity (torque) of the crane is fixed, the larger the working radius of the crane. The lighter the lifting cargo, the smaller the working radius, the heavier the lifting cargo. (The working RADIUS refers to the horizontal distance from the center of the moment to the hook.)
3: Considering the lifting size of the crane and the capacity of the chassis size, the girder is the larger the better, the crane is large and the chassis is small, will make the girder deformation and fracture. The chassis is small, the power of the engine is small, affecting the lifting capacity of the crane.
