132HC Mast Section The lifting moment of tower crane is the product of lifting component and corresponding amplitude
Tower crane Construction Co., Ltd. (http://www.fx68.net) is a production enterprise of Shandong tower crane, integrating R & D, design, production and sales. Can produce a variety of models, provide the latest and the most complete price of various models of tower crane. Next, let's introduce what is the lifting moment of tower crane, which is one of the important functional parameters of tower crane.

The so-called lifting moment is the product of the lifting component of the tower crane and the corresponding amplitude. The former calculation unit is T.M, and the current measurement unit is kn. M. Conversion Association: individual can be simplified as 1t. M = 10kN. M.
The maximum lifting moment is the most important parameter of the working ability of tower crane, which is the control value of the stability of tower crane. The lifting capacity of the tower crane decreases with the increase of the amplitude. Therefore, there is rated lifting capacity in various amplitude. Different amplitude and corresponding lifting capacity are drawn into the performance curve of the tower crane to express the additional lifting capacity in different amplitude. The common tower crane can be installed with different arm lengths, each of which has its own specific lifting curve.
All tower cranes are equipped with moment limiters in order to avoid accidents caused by over torque during tower crane operation.
