Standard permanent magnet jack
The permanent magnet jack uses high-performance magnetic materials to make it smaller in size, lighter in weight, and strong in holding. Special magnetic circuit design, the remanence is almost zero. The safety factor is high, and the maximum pull-off force is about 3.5 times of the rated lifting force. The handle switch is equipped with a safety button, which can be operated with one hand, which is convenient and safe. The bottom surface of the jack has a "V" groove design, which can lift the corresponding round steel and steel plate. No electricity, long-lasting magnetic force, safe to use. It can be used in the field and is widely used for lifting and transporting steel, smoothing mechanical parts, and installing and transporting various abrasive tools.
Holding force of single magnetic circuit permanent magnet jack:
(1) The material of the workpiece also has an impact on the lifting capacity of the lifter, and the lifting capacity for low-carbon steel workpieces can be taken as 100%;
(2) The surface roughness of the workpiece also affects the lifting capacity.
(3) When installing the rotating handle, the strong magnetic jack should be placed on the steel plate, so that the permanent magnetic jack can rotate freely under the condition of magnetic flux, otherwise, it will be difficult to rotate even with a lot of force handle. Do not install the handle in the wrong direction, the wrong direction will cause no suction. Once you find the wrong direction, you can use a small iron rod to turn the shaft core 180° to restore it to the normal position, and then reinstall it.
