Permanent Magnetic Lifters Model PML is mainly used for connecting
component. During lifting and handling operation. 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 hoisting devices in
factories, Docks warehouses and transportation industries. By using
them, you can improve Your working conditions and increase your
MODEL PML 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. There are shackles on
the top of Magnetic Lifting Hoist for lifting, a veto slot on the
holding face for holding cylindrical Component firmly.
1 During operation, you should clear away the components surface
such as rust and burr. The centerline of lifter had better overlap
with the centerline of component. Then place the Magnetic Lifting
Hoist on the face of component, turn the nozzle from"OFF" to "ON"
until "holding". Make sure that the security key on the handle is
auto-matically locked, and then start to hoist.
2 During lifting and handing components, overloading is forbidden.
Nobody is allowed to pass through under the component held by
Magnetic Lifter. Components temperature and ambient temperature
shall be between +80° C to -40° C. No strong vibration and impact.
3 When lifting and handling cylindrical components, Keeping the
cylindrical Surface contacting the Vee slot of lifter on two lines,
the actual lifting capacity will Generally be 30% of the rated
4 When lifting and handling operation is finished, press down the
bottom to disengage the security key from the security pin, 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.
Main factors which influence the lifting capacity o f permanent
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 (on the following page). If its
surface roughness Rais less than 6.3um, the lifter surface gap will
not exist, the lifting capacity will be 100%. If the surface
roughness Rais 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. Combine these two factors and
calculating the lifting capacity that the lifter may reach. The
curves are on the two sides of lifter.
2 Influenced by the composition of steel component After
measurement, if low-carbon steel component is regarded as reference
The coefficient of lifting capacity is fixed: The coefficient for
medium-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&
