Description

Technical Field

[0001] The utility model relates to the technical field of cranes, and more specifically, to an electric suspension crane with a remote control operation function. Background Art

[0002] An electric suspension crane is a type of lifting equipment driven by electricity and has a suspension system for lifting, moving and carrying heavy objects. Electric suspension cranes use an electric drive system, usually driven by an electric motor. This design provides higher power and efficiency, allowing the crane to handle larger loads and more complex tasks. The suspension system is the core component of an electric suspension crane, which includes a suspension device, steel cables or chains, etc. Through the suspension system, the crane can attach a hook or other lifting tool to the cargo and perform vertical lifting and horizontal movement. Some modern electric suspension cranes are equipped with a remote control operating system that allows the operator to remotely control the operation of the crane through a remote control. This remote control function improves the flexibility of operation and makes it easier to operate in special or dangerous environments.

[0003] In the existing technology, there are some shortcomings in the layout of the cranes and their power distribution equipment we use. The separate layout of the crane and the power distribution equipment leads to the dispersion and chaos of the workplace. This separate layout also increases the difficulty of maintenance and management, because the operator needs to spend more time and energy on the inspection, repair and maintenance of the equipment. At the same time, manual lifting work increases the labor intensity of the operator and even poses a safety hazard. Secondly, manual lifting is often inefficient and cannot meet the requirements of efficiency and speed in modern production, resulting in delays in production progress and increased production costs. In addition, the stabilizing device of the existing mobile crane is very inconvenient to operate, and even lacks a stabilizing device, which reduces the stability and production efficiency during lifting.
