Description

Permanent Magnetic Lifter

H-Lift Magnetic Lifter PML type
Permanent magnetic lifter is an equipment with a permanent magnetic field which creates sufficient force for gripping, holding and handling loads with ferro-magnetic properties. The magnetic field is controlled by mechanical means.

Permanent Magnetic Lifters are mainly used to lift steel plates, blocks, press molds, etc. and load / unload in machines during handling operation. They can hoist moving iron blocks and other magnetic material. They are easy to operate and safe to handle and hence are widely used as lifting devices in factories, docks, warehouses, and transportation industries. By using them, you can improve your working conditions and increase your working efficiency.

The Permanent Magnetic Lifter (PML) – a below-the-hook permanent magnetic lifting machine allows steel handlers to quickly and simply maneuver steel plate, pipes and rods without the use of slings, chains and blocking. In most applications, a two-man job could be accomplished with one man utilizing the lifting magnet. Being a permanent magnet, no external power is required, therefore eliminating the hazards associated with power magnets.

High-quality powerful NdFeB permanent magnets inside.
Light weight.
Designed to lift on both flat and circular surfaces. For models of 3000KG and above, we suggest using them only to lift iron plates rather than the circular iron material to avoid the risk.
Strong and durable painted steel housing with machined connection surface.
Wear and corrosion resistant Chrome plated shackle as the top connection.
The handle is equipped with a positive locking device.
Spare parts available.
Temperature range: -40°C – +80°C.
Finish: Painted housing and Chrome plated shackle.
Standard: EN 13155, AS 4991, B 30.20
Safety Factor(Tear-off Force): 3.5:1.M

PRINCIPLES FOR THE SELECTION OF MAGNETIC LIFTERS

Applications

Magnetic lifters can be suitable for a variety of applications. Some may be used as general purpose lifting accessories, and therefore require their capacity to be assessed for each application, whereas others may be dedicated to a single application and are selected specifically for it. However not every load with ferromagnetic properties can safely be handled with a magnetic lifter.

The magnetic lifter selected must match the characteristics of the load. As well as the weight, this includes the shape, surface finish and magnetic properties of the load.

The shape of the magnet should be compatible with that of the load. For example, a magnet with a flat face can handle sheet material whereas for lifting round section material, a magnet with a V shaped recess in the face is more suitable. For long loads, an arrangement of several magnets used in conjunction with a lifting beam is generally suitable as it provides the load with adequate support along its length. The position and capacity of the individual magnets should be such as to ensure that the share of the load imposed on each does not exceed its working load limit. For flexible loads, the positioning should provide support at short enough spaces to prevent the load from peeling off the magnet.

Lifting magnets are normally rated for lifting a horizontal load in the vertical plane only. If the line of pull is not at right angles to the plane of the load, their lifting capacity will be substantially reduced and slippage may occur.
For such applications, the advice of the manufacturer should be obtained.

Consideration should be given to the following:
(1) Lifting capacity required

(2) Characteristics of the load in terms of shape, surface finish and magnetic properties.
(3) Nature of the lifting operation.
(4) Lifting machine it is to be used with.
(5) Available headroom.
(6) Self weight of the magnetic lifter and degree of portability required.
(7) Method of control and control features required.
(8) Electrical requirements for electro or electro-permanent magnetic lifters.
(9) Proximity of persons during operations.
(10) Backup and other safety features required.
(11) The documentation required by legislation. If this is not on record, refer the magnetic lifter to a Competent
Person for thorough examination
