NOTE: Please read the Operating Instructions carefully before using this Product. If any doubt remains, please contact company for further details.
1. APPLICATION AND FEATURES
Permanent magnet lifters have the features of strong attraction, smaller volume, lighter weight, powerful lifting effort ,easy and safe to operate ,long-period effort and without power supply. They can hoist moving iron block.,cylindrical and other magnetic material. They are easy for operation, safe in handling, lightly and ingeniously structured. Hence they are widely used as hoist devices in factories, docks warehouses and transportation industries. By using them, you can improve your working conditions and increase your working efficiency.
2. CONSTRUCTION AND SPECIFICATION
2.1 construction: Permanent Magnetic Lifter has strong magnetic path produced by NdFeB magnetic materials. On and off the magnetic path is controlled by turning the manual nozzle. These are shackles on the top of Magnetic Lifting Hoist for lifting, a veto slot on the holding face for holding cylindrical component firmly.

3.1During operation, you should clear away the components surface such as rust and burr. The centre line of lifter had better overlap with the centerline of component. Then place the Magnetic Lifting Hoist on the face of component, pulling up the handle,then turn the handle from"OFF"to"ON"until "holding".
Make sure that the security key on the handle is automatically locked, and then start to hoist.
3.2During lifting and handing components, overloading is forbidden, Nobody is allowed to pass through under the component held by Magnetic Lifting. Components temperature and ambient temperature shall be between +80ºC to -40ºC. No strong vibration and impact.
3.3When lifting and handing cylindrical components, Keeping the cylindrical surface contacting the V Slot of lifter on two lines.
3.4When lifting and handing operation is finished, pulling up the handle,then turn the handle"ON"to "OFF"until "Release".The lifter is now in the neutral condition, it can be taken away from the component.
4. Main factors which influence the lifting capacity of permanent Magnetic Lifter.
4.1 Influenced by thickness and surface quality of the component. Before operation, it is necessary to find out the percentage of the steel thickness -lifting capacity according to the thickness of the component and capacity curve (see the following page).If its surface roughness Ra is less than 6.3 um, the lifter surface gap will not exist, the lifting capacity will be 100%.If the surface roughness Ra is above 6.3um or even worse, the lifter surface gap should be estimated. Find out the percentage that lifting capacity of the lifter may reach from the air gap-lifting capacity curve shown in the performance chart (see the following page). Combine these two factors and calculating the lifting capacity that the lifter may reach. The curves are on the two sides of lifter too.

|Air gap-lifting capacity curve|
4.2 Influenced by the composition of steel component.
After measurement, if low-carbon steel component is regarded as a reference and the coefficient of lifting capacity is fixed: the coefficient for middling-carbon steel is 0.95; the coefficient for high-carbon steel is 0.90; the coefficient for low-alloy steel is 0.75, and the coefficient for cast iron is 0.50.
5.Maintenance and safety Measures
5.1 While carrying and using permanent magnet lifter be ware of the bumping and roughing of surface, so as not to influence its property and working life. After using, the lifter had better be protected by oil. What's more, do not place the magnet lifter directly onto a grounded floor. Use a non-conductive spacer.
5.2 Please check the quality of the handle button frequently. Make sure that the security key can be moved flexibly and the security pin can be locked firmly.
5.3 Must take a test for the capability every year and check the safety of all of the components in order to ensure its use capability .Maintenance must be strictly according to the instructions by the professional authorized technical personnel.
5.4 Do not weld in close proximity to the magnet lifters, in order to protect its property.
5.5 Do not turn the handle, when magnet lifter is not in contact with ferromagnetic material of component.
5.6 Do not hoist a load weighing more than the lifer's rated holding capacity.
5.7 Forbid anyone stand below the magnetic lifter.
