Background

The tower crane is the most common hoisting equipment in construction sites, also called tower crane, and is used for hoisting construction raw materials such as reinforcing steel bars, wood ridges, concrete, steel pipes and the like for construction. The tower crane is an indispensable device on a construction site. The tower crane adopts a tower crane standard section to be connected with the tower crane standard section one section by one section, and a tower crane cab is arranged on the tower crane standard section opposite to the top end.

At present, a tower crane driver (driver for short) enters a tower crane cab in the existing building construction mainly has two modes: the first mode is as follows: when a building under construction is just constructed, a driver usually climbs a tower crane cab section by section from the interior of a standard section of the tower crane. The second mode is as follows: after the building reaches a certain height, a driver cannot climb into the cab from the standard section of the tower crane any more, so a temporary frame plate is usually erected between the outer side of the building and the standard section of the tower crane to serve as a passageway for the driver to enter the cab.

In the second method, after the driver usually takes the construction elevator to reach the building floor where the temporary frame plate is erected, the driver enters the standard section of the tower crane close to the cab from the temporary frame plate and climbs into the cab. Usually, interim frame plate adopts scaffold frame, template to build, and the interim frame plate of this kind of structure not only builds, dismantles more troublesome, wastes time and energy, builds, dismantles the in-process and has great potential safety hazard, and the security is not high enough.
