Description

Technical Field

[0001] The utility model relates to the technical field of slewing tower frames, in particular to a slewing tower frame of a tower crane. Background Art

[0002] Tower cranes are also called tower cranes, which originated in Western Europe. A rotating crane with a boom mounted on the top of a tall tower. It has a large working space and is mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. The slewing mechanism is a mechanism that enables the slewing part of a crane or other machinery to rotate around its slewing centerline to achieve slewing motion. It cooperates with other mechanisms to complete the spatial transportation task or other work cycle of goods. Most of the existing slewing towers of tower cranes have a power-off locking function. When a power outage occurs during the process of moving goods, the support seat will automatically lock. This to a certain extent prevents the slewing tower from swinging under the action of external forces, thereby ensuring the life safety of the staff. However, most of the existing power-off locking functions use emergency braking. During the braking process, the staff in the control room are prone to accidental injuries such as bumps due to inertia. Utility Model Content
