Abstract

A hoisting machinery comprises a steering wheel and wheels, wherein the active steering system comprises an active steering device, a hydraulic power steering gear and a hydraulic power steering system, the active steering device is arranged between the steering wheel and a pitman arm of the hoisting machinery, so as to adjust a steering ratio of the steering wheel to the pitman arm according to a driving cycle of the hoisting machinery, and the hydraulic power steering gear is arranged between the steering wheel and the pitman arm, so as to control the hydraulic power steering system to drive steering of the wheels. In the active steering system of the present invention, a hydraulic power steering system is adopted to drive steering of wheels, which can improve capability of overcoming steering resistance and can be applicable to multiple chassis of cranes, thereby enlarging application ranges of the active steering system.
