Structure & components

The carrier beam electro- magnet crane is mainly consisted of box-shaped bridges, double girder trolleys, cart operation mechanisms, crane operators cabin and electrical control system, installed with power failure protection system. The lifting mechanism of magnetic crane with double lifting points beam spreader usually adopts single motor, double speed reducer and double reel arrangement. And the electro- magnet beam spreader can be installed to the main girder either perpendicularly or parallel. And the other forms of the magnetic overhead crane are the same with the general use double girder overhead crane with hook.

Types of magnetic rotary crane designs

The magnetic hanging beam spreader overhead crane is with rotary crane designs, which enable the electro- magnet crane with high flexibility and convenience for steel loads handling. The rotation of the magnetic overhead crane can be achieved in two options:

Rotary overhead crane with lifting system 

It is the magnetic crane that adopts a rotary trolley over the main girder which is the so called upper rotary overhead crane. The rotary trolley is designed with a double-layer structure, the upper layer of which a lifting trolley, and the lower layer of which is a running trolley. And the upper lifting trolley can move on an annular track installed which can enable the loads to rotate as request.

Overhead crane with rotating beam spreader

The magnet crane adopts the rotary magnetic beam spreader, which is consisted of a double-layer structure. The upper layer of the magnetic hanging beam spreader is wound with a wire rope through a pulley set and the lower layer is equipped with multiple electromagnetic chuck or clamps, which can carrier the loads to rotate with the driving mechanism to a angle as requested. Magnetic crane with the rotary magnetic beam spreader is usually called the lower rotary overhead crane in China.

Lower rotating electromagnetic carrier-beam overhead crane

Electromagnetic beam spreader

General use electromagnetic spreader is mainly consisted of carrier-beam , electromagnet, and hook, etc., The spacing of electromagnet be adjusted according to operation requirements, the orientation of the electromagnetic beam spreader can be perpendicular or parallel to the main beam according to requirement. The body of electromagnetic spreader is a welded box shaped beam with upper and lower cover, webs, ribs, lifting lug and other plates, etc. Electromagnetic carrier-beam is through overall processing, to ensure its machining and assembly accuracy.

Electromagnetic carrier-beam spreader for overhead crane

Electromagnet is an important part of the electromagnetic crane, and there are various types of electromagnets for selection based on application requirements:

For general handling with loads temperature below 100 degrees, the room temperature electromagnet may be is a option. For handling iron with temperature between 100 to 600 degrees,the high temperature electromagnet is used. In terms the design of the beam spreader, the magnet can be mounted on the rotating carrier-beam and retractable carrier-beam. The length of the carrier-beam is adjustable according to the size of the lifting object, and the spacing of hanging points is also adjustable which providing you a more flexible and convenient rotary magnetic crane with high accuracy and safety.

Convenient and safe electromagnet crane is a ideal solution for steel loads handling in your workshops. Contact us to get your individualized magnetic crane solution.

Main feature of magnetic cranes
