Description

A high-stability side-hung crane

Technical Field

The utility model relates to the technical field of cranes, in particular to an eccentrically hung crane with high stability.

Background Art

A crane is a lifting equipment that is horizontally mounted above a workshop, warehouse, or material yard to lift materials. The more common ones include bridge cranes, gantry cranes, etc., which mainly use a trolley to drive an electric hoist or drum to move on the main beam, and then lift the heavy object to move it to operate. Existing cranes usually hang the electric hoist under the main beam for operation. This method ensures that the lifting center of gravity of the crane is basically located under the beam to prevent tilting, but this method reduces the effective lifting height of the crane. The utility model patent with application number 202220890390.4 discloses an anti-drift single-beam metallurgical crane. By setting a hydraulic rod, a sliding rod, a transmission shaft, a rotating rod, a transmission groove, a pressure block, and an anti-skid pad, the frame and the track beam are firmly connected, which can effectively prevent the sliding friction between the walking wheel and the track beam after the hook or the frame itself is subjected to external force, but the structure is relatively complex, the manufacturing cost is high, and it cannot solve the technical problem of reducing the effective lifting height.
