Lifting tower in the process of using the left and right slip rope firmly, slewing to the required height, need to slowly descend to the fixed base point, to avoid accidents and wear and tear too quickly. On the way of installation, if found problems first emergency measures, after processing and then lifting work.
1. The crane lifting capacity is fixed, the larger the working radius of the crane. The lighter the lifted goods, the smaller the working radius, the heavier the lifted goods. The working radius is the horizontal distance from the moment center to the hook.
2. Understand the size of the lifting goods, 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.
3. Consider the lifting weight of the crane and chassis size capacity, beam is to choose the bigger the better, the crane is big and chassis is small, will make the beam deformation and fracture. Chassis is small, the engine power is small, affecting the lifting capacity of the crane. So when we consider 230mm beam, we choose the crane below 3 tons. When we consider 250mm beam, we consider crane under 6 tons. 280mm beam can choose crane under 8 tons. Chassis like rear eight wheel and front four can consider crane under 10 tons.
