Electro-hydraulic rubber tyred gantry crane

Abstract

An electro-hydraulic rubber tyred gantry crane comprises two horizontally arranged lower longitudinal beams. A front portal frame is arranged between the top surfaces of the front ends of the two lower longitudinal beams and a rear portal frame is arranged between the top surfaces of the rear ends of the two lower longitudinal beams; the left side and the right side of each of the front portal frame and the rear portal frame are respectively provided with an upper longitudinal beam; the lower surfaces of the front end and the rear end of each lower longitudinal beam are both provided with a walking steering system, wherein a bracket is arranged under one lower longitudinal beam and the bracket is provided with an engine, a transfer case, a hydraulic station and a generator set; each lower longitudinal beam is provided with an engine and winches arranged in front of and behind the engine; the one lower longitudinal beam is provided with a driving cab for controlling walking and steering of the walking steering system and lifting of a lifting system. According to the invention, the electro-hydraulic combined drive method is adopted, large-tonnage cargo can be lifted, short-distance transmission of awkward cargo inside the factory is completed, and the electro-hydraulic rubber tyred gantry crane realizes the functions of transverse walking, vertical walking, 360-degree in-situ rotation, braking and winching and lifting heavy goods.

Description

technical field [0001] The invention relates to a special equipment for large cargo transfer, in particular to an electro-hydraulic drive 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 an electro-hydraulic driven tire-type gantry crane with low cost, strong flexibility and wide application. [0004] In order to ...
