Lifting hook bridge crane of double generator operation mechanism

Abstract

The invention relates to a hook bridge crane with double motors, wherein said crane is characterized in that: its operator is formed by two motors and dual-output-axle speed reducer; two motors are connected to left and right input axles of speed reducer; the power wires of two motors are connected to one switch; and it commonly uses one motor; when there is accidence, it switches to another motor, with short stop time without affecting the irrigation of steel liquid.

Description

technical field [0001] This application pertains to lifting equipment, in particular to cranes. Background technique [0002] The operating mechanism of the traditional hook bridge crane is driven by a motor on the bridge legs. Because the motors on both sides are sometimes out of sync, it is easy to make mistakes during walking, causing overcurrent damage to the motor and failure. When one side When the motor fails, it takes a long time to get rid of the fault, and it is impossible to resume walking immediately. If you can't stay in the foundry, once you stay, the molten steel will solidify. Contents of the invention [0003] The purpose of this application is to overcome the deficiencies of the prior art and provide a hook bridge crane with a double motor operating mechanism. [0004] The technical solution of the present application is: it includes a hook bridge crane, which is characterized in that the operating mechanism of the hook bridge crane is composed of two m...
