Abstract

The invention relates to a translator of crane, wherein it comprises a carrier cart and a driver; the driver is on the cart; the driver comprises hydraulic cylinder, hydraulic pump, lever, and steel wire coiling system; there are four groups of hydraulic cylinders while each two are mounted at one side of cart; one end of each hydraulic cylinder via base is fixed on the cart, while another end is connected to the upper end of lever; the support point of lever is fixed on the of cart; the lower end of lever has steel wire coiling system to connect the lifter upper frame; the hydraulic pump is between four hydraulic cylinder groups and connected to each cylinder; the steel wire coiling system comprises steel wire, block, and steel wire roller. The invention has simple structure, while it can translate the lifter on the large cart of crane and rotate lifter, etc.

Description

technical field [0001] The invention relates to an auxiliary tool for container loading and unloading equipment, and more specifically, relates to a crane spreader translation device. Background technique [0002] The existing container loading and unloading equipment used in the container yard mainly includes: container tire type gantry crane (RTG) and rail type gantry crane. Because in the container loading and unloading operation, it is impossible for the container transport truck to stop just parallel to the spreader of the crane, that is, the center line of the container on the container transport truck and the center line of the spreader of the crane produce a certain deflection angle. At this time, it is necessary to use The spreader slewing device installed on the crane equipment rotates at a certain angle, so that the centerline of the spreader coincides with the centerline of the container, and the operation can be continued after adjustment. The spreader slewing ...
