Exhibition:

A Tower Crane is an inverted L-shaped structure that is capable of lifting several tons of weight to precarious heights.
The most striking feature of this crane is that it is self-building and can allow a building to be constructed adjacent to or even around it.
Tower crane mast section ( tower crane mast and tower crane basic mast ) is a steel structure with a normally square section, whose main mission is to provide the tower crane with sufficient height.
Normally it is formed by lattice modules that facilitate the transport of the crane. For assembly, these modules will be joined by screws, all of which will be connected to the projected height. Its shape and dimension vary according to the necessary characteristics of weight and height.
Overall, the mast section is a critical component of a tower crane, providing the necessary height and support for the crane to perform its lifting and moving operations.
BQ also supplying other Steel Structure spare parts of tower crane like Basic Mast Section, Fixing Angle (or Reusable Fixing Angle), Anchorage Frame,Telescoping Cage Jacking Cage, Tower Crane Yoke, Hook and so on.
