AI Technical Summary

Technical Problem

When installing a luffing jib tower crane near a cliff face, space constraints make it difficult to achieve normal installation using existing methods.

Method used

The structure of the luffing tower crane is broken down into the counterweight boom, counterweight system, tower cap, drive assembly and working boom, which are assembled and installed under the tower body. This includes the foundation construction of the foundation steel bars, tower crane embedded parts, anchor bolts and concrete base. The assembly and rotation connection of the tower body are achieved through the jacking mechanism and slewing assembly.

Benefits of technology

The luffing jib tower crane was successfully installed in a small construction area, solving the installation problem near the cliff face and enabling the normal use of the luffing jib tower crane.
