Permanent Magnet Manual Lifter
The Magnetic Lever Lifter is a manually controlled permanent magnet lever designed for moving (lifting, transporting and lowering) ferromagnetic materials [e.g. sheet metal (plate or round shape), usually iron materials] .
The Magnetic Lever Lifter is a manually controlled permanent magnet lever designed for moving (lifting, transporting and lowering) ferromagnetic materials [e.g. sheet metal (plate or round shape), usually iron materials].
Such lifting equipment utilizes the properties of permanent magnets to create a magnet field capable of attracting ferrous materials. Within the equipment, it is activated by a lever that rotates a core containing neodymium magnets with strong magnetic properties; the magnetic current obtained in this direction passes through the load to be moved during the operating phase and short-circuits in the lever during the release phase. Since they are made of permanent magnets, they work without an electronic circuit and are not affected by power outages. They are safer to use than electromagnetic systems.
Fields of Application:
Machinery workshops, metallurgical and mechanical workshops, iron and steel workshops and all workplaces that require fast, reliable transportation of iron loads with the help of bridge cranes or cranes in general.
Working Principle:
During operations, you should clean the surface of components such as rust and burrs on the sheet metal surface. The Magnetic Lifter must be placed in the center of the sheet metal part to be transported. Then place the crane on the face of the Magnetic Lifter, turn the Lever from the “-” position to the “+” position until it “holds”. Ensure that the safety switch on the handle is locked automatically and then start lifting. Overloading during lifting and transportation of sheets is prohibited. No one is allowed to pass under the sheets held by the Magnetic Lifter. The temperature and ambient temperature of the Fe content metal to be transported must be lower than 80 ºC. There should be no strong vibration and impact. When lifting and holding cylindrical parts, the actual lifting capacity will generally be 30-50% of the rated lifting capacity, while ensuring that the cylindrical surface makes contact with the lifter’s V-Slot in two lines.
When the lifting and transporting process is finished, press the lower part to remove the safety switch from the safety pin, and then turn the lever to the “+” position “-” until “Release”. Magnetic Lifter with Arm can be taken on the part surface while the lifter is in neutral state.

Factors affecting lifting capacity
The main factors affecting the lifting capacity of the Permanent Magnet Magnetic Lifter.:
- It is affected by the thickness and surface quality of the component.
- Before operation, it is necessary to find out the percentage of steel thickness-lifting capacity according to the component and capacity curve. If the surface roughness is less than Ra 6.3 um, there will be no lifter surface gap, the lifting capacity will be 100%. If the surface roughness is above or worse than Ra 6.3 um, the lifter surface clearance should be estimated. Find out the percentage that the hoisting capacity of the lifter can reach from the air gap hoisting capacity curve shown in the performance table. Combine these two factors and calculate the lifting capacity that the lifter can reach. The curves are on both sides of the lifter.
- It is affected by the composition of the steel component.
- After measurement, if the low-carbon steel component is taken as reference and the lifting capacity coefficient is fixed: the following table can be taken as a basis.
