Double-drive walking type chassis crane

Abstract

The crane with dual power driven chassis includes a chassis and a crane on the chassis. The chassis platform has four legs connected through leg extending oil cylinder or two legs connected through leg extending oil cylinder and the other two legs fixed to the platform. Two guide and support tracks are provided with walking oil cylinders. The dual power driving apparatus in the platform includes a diesel engine driven pump unit and a motor driven pump unit. The crane has easy moving in the operating field, and may be also used in place without power supply.

Description

technical field [0001] The invention relates to a mobile crane, especially a crane with a dual-power-driven walking chassis. Background technique [0002] Existing movable crane generally adopts such structure: the crane is installed on the automobile chassis or on the crawler chassis or on the fixed track. The first two structures are difficult to move on the road surface of the poor work site, and the power of the crane adopts the whole machine walking power of the chassis, and the power is relatively large, far exceeding the required power, resulting in waste; the latter structure needs to lay tracks, Subject to site restrictions. Contents of the invention [0003] In order to overcome the shortcomings of the existing mobile cranes, the present invention provides a crane installed on a dual-power drive walking chassis, which is convenient to move even on the road of a poor job site, and the stability of the chassis platform Strong performance, the set power equipment ...
