double magnetic circuit lifting magnets manual lifting magnets permanent magnetic lifter

 Double magnetic circuit lifter is mainly used for connecting steel workpiece during lifting and handling operations.

They can hoist and move steel plates,blocks,cylindrical and other ferromagnetic material.It's easy to operate and

its structure is compact with low self-weight.Hence they are widely used as hoisting devices in factories,docks,

warehouses and transportation industry.By using them ,you can improve your  working efficiency greatly.

Constructions:

Double magnetic circuit lifters have strong magnetic path by NdFeb magnetic materials.On and off magnetic path is controlled by  turning the manual handle.

On and off the magnetic path is controlled by turning the manual handle.

Strong magnetism,low self-weight,little residual magnetism on released condition, showing of its precise design.

parameters of magnetic lifter

Details

high strength alloy rigging ring

It is made of high strength alloy  and forged process,owning good wear resistance and capacity.

U shaped  groove

four U shaped grooves increase magnetism contact area.

The graph for steel thickness and loading capacity

It can be used to lift thin plate ferromagnetic material  provided the thickness is more than 5mm

High strength alloy lever covered by rubber 

The rubber supplies good friction for handling and rotating the lever.

The damper strength for operating which is only 30%-40% compared with the single-magnetic ones.
