What's a tower lifting weight? The lifting weight of the tower is the weight that the hook can lift, including the weight of the Sling, Sling and container. The lifting weight includes two parameters: the maximum lifting weight and the maximum lifting weight.
The starting weight changes with the change of the amplitude, so each tower crane has its own corresponding table of starting weight and lifting amplitude, commonly known as the working curve table.

The maximum lifting weight is determined by the design structure of the crane, which mainly includes its wire rope, hook, arm frame, and lifting mechanism. Its hanging point must be in a smaller position. The maximum lifting weight is not only related to the crane design structure, but also related to its tipping moment, which is a very important parameter.
The lifting weight of the tower varies with the number of pulleys on the hook. In general, two ropes are twice the weight of a single rope, and four ropes are twice the weight of two ropes. It can be transformed as needed.

In order to prevent the lifting of the tower from exceeding its maximum lifting weight, all tower lifts are equipped with weight limiters, some of which are called force measuring rings. The weight limiter is equipped with multiple limit switches, except for the maximum rated weight of the limited tower lifting. When lifting at high speed and at medium speed, Weight restrictions can also be carried out. The weight of lifting at high speed is the lightest, the weight of lifting at medium speed is medium, and the weight of lifting at low speed is the heaviest.
