自由容器

Configured Around
Your Steel Load

Electromagnetic overhead cranes are configured according to the load shape，dimensions， material grade, surface condition，temperature, working air gap and handling process.

Steel Plates & Sheets

Single plates, stacked sheets

and cut steel

Billets & Slabs

Hot or cold semi-finished

steel products

Beams & Profiles

Structural sections, bars and

lona steel loads

Cut Parts & Skeletons

Burn-table parts and

remaining steel skeletons

Scrap & Turnings

Loose ferrous scrap and

irregular steel material

Steel Service Centers

Storage, sorting and production-line feeding

The load material, dimensions, thickness and surtace condition must be confirmed before the magnet capacity and arrangement are selected.

Technical Specifications

Key data for crane and magnet system configuration.

Final crane and magnet selection depends on the load material, contact area, surface condition, working air gap, temperature, magnet self-weight and required operating cycle.

Frequently Asked
Questions

What is an electromagnetic overhead crane?

It is an overhead crane equipped with an electrically

controlled lifting magnet system for handling

ferromagnetic steel loads.

Can it lift every type of metal?

No. It is intended for ferromagnetic materials. Aluminum, copper and many stainless-steel grades may not provide suitable magnetic attraction.

How is magnet lifting capacity selected?

It is selected from the load material, dimensions,

thickness,surface condition, air gap, temperature

and contact area.

Does rust or scale affect magnetic lifting?

Yes. Rust, scale, paint, uneven surfaces and other

gaps can reduce magnetic contact and require

capacity derating.

Can one magnet handle long steel plates?

Not always. Long or flexible loads may require

multiple magnets and a spreader beam to improve

support and load stability.

Can it handle hot steel?

Yes, when the magnet, insulation, cables and

control system are designed for the actual steel

and ambient temperature.

What happens if electrical power is

interrupted?

The response depends on the selected magnet and

power system.The load-retention and emergency

strategy must be confirmed during project

engineering.

Can the crane use multiple magnets?

Yes. Multiple magnets can be controlled together or in groups according to the load length and handling process.
