Permanent magnetic lifter
The permanent magnet jack consists of a high-performance NdFeB permanent magnetic material to form a strong magnetic system. Through the rotation of the handle, the magnetic force of the strong magnetic system is changed to achieve the suction and release of the workpiece. The upper part of the jack has a lifting ring for lifting the object, and a V-shaped groove is provided for holding the corresponding cylindrical object. The high-performance permanent magnet material used in the permanent magnet jack is: rare earth permanent magnet and neodymium iron boron as the magnetic source, which has the characteristics of no power consumption, strong suction force, low residual magnetism, light operation, long life, safety and reliability. Suitable for handling steel plates, iron blocks and cylindrical iron. Such as mechanical parts, punching molds and various steel materials.
A permanent magnet jack is a powerless lifting device. The structure of the permanent magnet jack is advanced, and the production is organized according to the export standard, and the quality performance has reached the advanced level of the international similar products. Permanent magnet jacks are widely used in the mechanical industry, mold manufacturing, production workshops, dock warehouses and transportation departments to transport magnetic objects such as steel plates and steel ingots.
1. Compact structure, the shape is compact, easy to operate
2. High performance permanent magnetic materials, no demagnetization
3. Work or other power without the need for electricity
4. Advanced scientific balance of magnetic circuit design, strong holding force, residual magnetism is almost zero, safe and reliable
5. The maximum pull force is 3.5 times of the rated lifting force, high safety coefficient
Permanent magnet crane use and precautions
1. When lifting, first clean the surface of the workpiece to be lifted. If there is rusty skin and burrs, it should be cleaned. The center line of the permanent magnet jack preferably coincides with the center of gravity of the workpiece, and then the jack is placed on the working plane, and the rotating handle is rotated from the "-" position to the "+" direction to the limit pin. Check that the security guard block of the handle is automatically locked and then lifted.
2. When the workpiece is lifted, overloading is strictly prohibited. It is strictly forbidden for the human body to pass under the workpiece. The temperature and ambient temperature of the workpiece to be hoisted are not more than 80 degrees, and there is no severe vibration and impact.
3. When lifting the cylindrical workpiece, the B-shaped groove should be kept in contact with the workpiece in two straight lines, so its lifting force is only 30%-50% of the rated gravity.
4. After the lifting is completed, press the handle button inward, and the security button on the handle is separated from the security pin. The handle is rotated from the "+" to the "-" direction to the limit pin. Lifter
