Document Type and Number:

WIPO Patent Application WO/2018/102956

Kind Code:

A1

Abstract:

An active steering system for use in hoisting machinery, and hoisting machinery, the hoisting machinery comprising a steering wheel (1) and vehicle wheels, the active steering system comprising an active steering apparatus (3), a hydraulic power steerer (6) and a hydraulic power steering system, the active steering apparatus (3) being disposed between the steering wheel (1) and a vertical steering arm (7) of the lifting machinery, so as to adjust a steering transmission ratio between the steering wheel (1) and the vertical steering arm (7) according to driving conditions of the lifting machinery, and the hydraulic power steerer (6) being disposed between the steering wheel (1) and the vertical steering arm (7), so as to control the hydraulic power steering system to drive the vehicle wheels to steer. The present invention uses a hydraulic power steering system to drive vehicle wheels to steer and hence can increase ability to overcome steering resistance, and is applicable to multiple types of crane chassis, increasing application scope of the active steering system.
