Description

A cap beam lifting auxiliary device

Technical Field

The utility model relates to the field of building construction equipment, in particular to a cap beam hoisting auxiliary device.

Background Art

The cap beam is a reinforced concrete beam installed on the pier or on the pile row. Its main function is to support the superstructure of the bridge and transfer all loads to the lower structure.

When the cap beam is prefabricated, it is necessary to embed lifting points on its surface. During the lifting construction, equipment such as cranes or hoists are connected to the lifting points through wire ropes, and then slowly rise to lift the cap beam from the ground to the top of the building. During the lifting operation, since multiple wire ropes are hung on different lifting points, the horizontality of the cap beam is difficult to control and it is easy to tilt. In addition, the wire rope has a certain length between the crane hanging point and the cap beam hanging point. The stability during the lifting process is not high, and the lifting speed and action requirements are high, which is not conducive to the smooth lifting of the cap beam and accurate installation in the predetermined position. This needs to be improved.
