APPLICATION AND FEATURES


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 working efficiency.

CONSTRUCTION AND SPECIFICATION

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.

We also supply magnetic chucks with Max pull-off strength= 3.5 X rated lifting strength

OPERATIONS

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 lifting capacity.
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  Magnetic  Lifter
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 and
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








Maintenance and safety notice

1 While carrying and using permanent magnetic lifter beware of the bumping and
roughness of surface. So as not to influence its property and life-span. After using, the lifter had better be protected by oil.
2 Please read the operating instruction carefully and know its property before using
this lifter to avoid accident. Please contact our company for further detail.
3 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.
4 When Magnetic Lifting Hoist is not in contact with ferromagnetic material of
component, don’t turn the nozzle.
5 Maintenance must be strictly according to the instructions by the professional
authorized technical personnel.
6 Prohibit modifying the products to avoid effecting on their safety.
7 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.
8 If its main body and turning part is damaged so that it can not work,　it should be
discarded as useless.
