AI Technical Summary
Technical Problem
The existing gantry cranes have complex beam structures and excessively large dimensions, resulting in an overall oversized crane that is difficult to install and transport.
Method used
The system employs a slewing frame that integrates lifting and translation anti-sway components. The lifting component raises or lowers the spreader, while the translation anti-sway component controls the spreader's posture, simplifying the beam structure and reducing the design complexity of the crane.
Benefits of technology
It achieves stable lifting and attitude control of the lifting device, simplifies the crane beam structure, reduces the overall size and weight of the crane, and facilitates installation and transportation.

Abstract
The present application belongs to the field of hoisting equipment, and discloses a slewing trolley frame and a crane. The slewing trolley frame comprises a trolley frame body, a hoisting assembly and a translation roll stabilization assembly. The hoisting assembly comprises a first driving part and a first transmission part. The first driving part is arranged on the trolley frame body, and the first transmission part is drivingly connected to the first driving part to lift or lower a lifting appliance. The translation roll stabilization assembly comprises a second driving part and a second transmission part. The second driving part is arranged on the trolley frame body, and the second transmission part is drivingly connected to the second driving part to control the posture of the lifting appliance. In the present application, the first driving part drives the lifting appliance to lift and lower. The translation roll stabilization assembly can avoid the lifting appliance from shaking during lifting or lowering, and the control of the lifting appliance is concentrated on the slewing trolley frame, thereby reducing the design complexity of the cross beam of the crane.
