select the permanent lifting of the several criteria

Permanent lifting lifting process to be used for lifting the workpiece and being connected for moving iron block and a cylindrical magnetic materials work. Easy to operate, safe and reliable,

Results compact and lightweight. Widely used in factories, docks, warehouses and transportation industries. Improving the working conditions of loading and unloading operations, improve labor efficiency. In the choice of

Permanent lifting, the need to magnetic sweeper pay attention to the following points:
The first consideration is the safety factor of permanent lifting, lifting only your permanent operational safety is the most important. So we come to a detailed understanding of a

Under the permanent lifting of the safety factor. In fact, the safety factor is to pull-off force size. Permanent lifting and other products primarily to attract hanging steel, mainly in lifting steel rose

The moment, shaking plate in an unstable state, will produce inertial force, this force is much greater than its own weight plates. Our permanent lifting safety factor

Reached 3.5 times, permanent lifting safety factor is higher, the pull-off force on behalf of its greater safety of operation is higher. Thus, the use of my company's permanent

Jacks is the most reliable.
The second is the permanent lifting of the appearance of the structure, the appearance of good quality permanent lifting compact, structured, the appearance of special treatment process, magnetic bar and the surface is not smooth

Rust wear.
The final step is to consider permanent lifting of the internal circuit design, that is, the size of the internal magnetic field, magnetic remanence size and determine the amount of permanent lifting of use

, Magnetic larger remanence more permanent lifting of the use of a long time is longer.
