Full hydraulic drive tire type gantry crane

Abstract

The invention discloses a full-hydraulic drive rubber tyred gantry crane. The full-hydraulic drive rubber tyred gantry crane comprises two lower vertical beams which are arranged horizontally, wherein a front portal frame is arranged between the upper surfaces of the front ends of the two low vertical beams; a back portal frame is arranged between the upper surfaces of the rear ends of the two lower vertical beams; the left and right sides of the front portal frame and the back portal frame are provided with an upper vertical beam respectively; the lower surfaces of the front end and the rear end of each lower vertical beam are provided with a walking-steering system respectively; a support frame is arranged under one lower vertical beam and provided with an engine, a lifting hydraulic pump, a walking-steering hydraulic pump, a hydraulic oil tank and a fuel oil tank; each lower vertical beam is provided with two hydraulic winches respectively; one lower vertical beam is provided with a driving control room which is used for controlling the walking and steering of the walking-steering system and the lifting of a lifting system. By using a full-hydraulic power drive manner, the large-tonnage goods can be lifted; the full-hydraulic drive rubber tyred gantry crane is capable of performing the operation of transferring the large goods in a short distance in a factory and has functions of walking transversely and vertically, rotating in 360 degrees on site, braking, winding and lifting heavy goods.

Description

technical field [0001] The invention relates to a special equipment for large-scale goods transfer, in particular to a fully hydraulically driven tire-type gantry crane. Background technique [0002] For the large-tonnage cargo transfer operations in the yard, the traditional method mainly uses truck cranes or rail-mounted gantry cranes. Truck cranes are mainly suitable for the transfer of small-tonnage cargo. For large-tonnage cargo, due to the high-tonnage truck cranes. Therefore, traditional gantry cranes are generally used to transfer large-tonnage cargo. However, due to the need to lay steel rails, this type of gantry crane can only be hoisted and transferred on both sides of the rails, which has poor flexibility and applicability. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a fully hydraulically driven tire-type gantry crane with low cost, strong flexibility and wide application.
