What working with an attachment brings
On a scrap site, the crane works not with a hook but with a magnet or a grab. This fundamentally changes the crane's electrical and control design: the attachment needs its own power supply, control and safety logic.
For magnets, the most critical issue is a power cut. When power is lost, the magnet drops its load; to prevent this, backup power (battery or generator) is an integral part of the system.
Environmental conditions
Waste and scrap sites are dusty, humid and often open areas. An elevated protection rating for electrical components, an enclosed conductor line and a corrosion-resistant paint system are used.
Rope and runway maintenance intervals shorten in this environment; the maintenance program must be planned around it.
Typical solutions
| Requirement | Solution |
|---|---|
| Scrap handling | Lifting magnet, backup power system |
| Bulk waste | Grab (bucket) attachment |
| Outdoor site | Gantry crane, storm anchor, elevated IP rating |
| Continuous operation | Upper duty class, planned maintenance |
| Dust and moisture | Enclosed conductor line, protected motor and panel |
| Corrosion | Heavy-duty paint system, water-shedding detail design |
Frequently asked questions
Can I fit a magnet to my existing crane?
This isn't an attachment add-on but a system change: it requires power supply, controls and backup energy. The magnet's own weight is also deducted from capacity.
Grab or magnet?
It depends on the material. For non-magnetic or mixed waste, a grab; for sheet and iron scrap, a magnet is efficient. Some facilities plan for both to be interchangeable.
