Gantry crane achieving double-beam double-set crane operation

Abstract

The invention discloses a gantry crane achieving double-beam double-set crane operation. The gantry crane comprises a gantry crane main body, wherein conveying ladder type fixed racks are arranged at the two ends of the gantry crane main body, a lifting conveying ladder is arranged in each conveying ladder type fixed rack, and two beam crane arms are erected between the conveying ladder type fixed racks; electrically controlled automatic door opening bodies are installed on the portions, at the two ends of a conveying vehicle marching rail, of an inner side rack body of each conveying ladder type fixed rack; a sliding rail is arranged at the bottom of the first beam crane arm, a wire sling electric hoist is connected to the sliding rail in a sliding manner, the upper end of the second beam crane arm is laid with a hoisting trolley operating rail, and a hoisting trolley device is connected to the hoisting trolley operating rail in a sliding manner; and a multifunctional sign post is further arranged at the upper end of the second beam crane arm, and a processing table is further arranged at the center of the upper end face of the second beam crane arm. In this way, according to the gantry crane achieving the double-beam double-set crane operation, the first beam crane arm and the second beam crane arm can be provided for performing hoisting work, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a gantry crane with double girders and double cranes. Background technique [0002] The gantry crane is a type of bridge type crane in which the horizontal bridge is set on two outriggers to form a gantry shape. This kind of crane runs on the ground track and is mainly used for handling and installation in open storage yards, docks, power stations, ports and railway cargo terminals. However, traditional gantry cranes use single girders for hoisting work, which cannot realize simultaneous hoisting of multiple girders, which reduces work efficiency. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a gantry crane with double girders and double cranes, which can provide two booms, the first beam boom and the second beam boom, to carry out hoisting work, greatly improving work efficiency. [0004] In order to solve the above-mentio...
