Abstract

The invention relates to the field of cranes, specifically to an electric hoist portal crane. The electric hoist portal crane provided by the invention is composed of buffers, active wheel assemblies, decelerators, motors, trolley frames, a 20-ton electric hoist, a 5-ton electric hoist, passive wheel assemblies, trolley protective covers, a 40-ton electric hoist, a track, a winding leg and a main beam. The winding leg is fixedly connected with the main beam. The track is laid on the main beam. Two trolleys are disposed on the track. The active wheel assembly and the passive wheel assembly of each trolley are arranged on the track of the main beam. The active wheel assembly and the passive wheel assembly of each trolley are fixed on the trolley frame through wheel shafts. Two ends of each trolley frame on the track are provided with buffers. Each motor and each decelerator are disposed at the inner side of one end of each trolley frame. The motors are connected with the decelerators. The 20-ton electric hoist and the 5-ton electric hoist are mounted in one trolley frame and the 40-ton electric hoist is mounted in the other trolley frame. The trolley protective cover is arranged on each electric hoist.

Description

technical field [0001] The invention relates to the field of cranes, in particular to an electric hoist gantry crane. . Background technique [0002] Cranes can be divided into electric hoist gantry cranes and electric hoist semi-gantry cranes according to their structure; cranes are divided into electric hoist hook gantry cranes, electric hoist grab gantry cranes and electric hoist electromagnetic gantry cranes according to the pick-up device; The number of main girders can be divided into electric hoist single main girder gantry cranes and electric hoist double main girder gantry cranes. [0003] The gantry crane is a kind of deformation of the bridge crane, which is mainly used for loading and unloading operations of ports, outdoor cargo yards, stockyards, and bulk cargo. Its metal structure is like a door-shaped frame. Two legs are installed under the main beam, which can directly walk on the track on the ground. The two ends of the main beam can have outrigger cantil...
