Lifting Gear Direct To You!

Permanent Lifting Magnet

Lifting Equipment LTD is able to supply a range of permanent lifting magnets; A permanent lifting magnet provides an efficient and cost effective way of lifting heavy ferromagnetic loads like mild steel, and can be used on flat as well as cylindrical materials.

Permanent lifting magnets are commonly used in the steel industry, or where steel is regularly handled, in particular, steel plate; they are also used in areas such as ship yard scrap yards, workshops, machine shops and warehouses.

A lifting magnet is ideal for use alongside electric hoists and cranes and other Lifting Equipment LTD can supply. We can provide lifting magnets in 6 different lifting capacities ranging from 100Kgs up to 2000Kgs all of which are supplied with a safety locking handle, to prevent unintentional discharge of the load.

The permanent lifting magnets that we supply present an effortless one man installation, simply hook on to your hoist hook or crane hook and lifting may begin.

• 6 capacities from 100Kg to 2000Kg load
• No running costs
• Safety locking handle
• One man installation
• One man operation
• Low self weight
• Contact area not marked
• Fully tested with certification
• Small dimensions

Contact Area & Material Type

Lifting magnets can only achieve their full lifting capacity when total contact is achieved with the material. Some factors will influence whether absolute contact is made, such as holes, dents or an uneven surface, these factors will decrease performance; during these conditions always do a test lift first to establish a correct and safe lift.

There are certain materials that have varying capabilities to carry magnetism for any material other than mild steel a reduction factor will need to be used, to determine the effective clamping force.
