154HC Mast Section What is the lifting capacity of the tower crane, the maximum lifting capacity
Lifting capacity includes two parameters: maximum lifting capacity and maximum lifting capacity. The lifting capacity changes with the change of the amplitude, so each tower crane has its own lifting capacity and the corresponding table of the lifting capacity, commonly known as the working curve table. The maximum lifting capacity is determined by the design structure of the crane, mainly including its wire rope, Hook, boom, lifting mechanism and so on. The lifting point must be in a less wide position.

The maximum lifting capacity is not only related to the design structure of the crane, but also to its tipping moment, which is an important parameter. The lifting weight of the Tower Crane varies with the number of pulleys of the hook. Generally two ropes are double the weight of the single rope, four ropes are double the weight of the two ropes, and so on. It can be changed as needed. In order to prevent the tower crane from lifting more than its maximum weight, all tower cranes are equipped with weight limiter, some are called force rings, and there are many limit switches in the weight limiter In high-speed lifting and medium-speed lifting, but also can carry out weight limitation, high-speed lifting the lightest weight, medium speed lifting medium weight, low-speed lifting the heaviest.
