Magnetic lift, also known as permanent magnet jack by high-performance Ndfeb permanent magnetic material composed of a strong magnetic system, through the rotation of the handle, change the strong magnetic system magnetic force to achieve the workpiece holding and release. The upper part of the jack has a lifting ring for lifting objects, and the lower part has a V-shaped groove for holding the corresponding cylindrical objects. The high performance permanent magnet material used by the magnetic crane is: rare earth permanent magnet - Ndfeb as the magnetic source, with no power consumption, strong suction, low remanence, light operation, long life, safety and reliability, etc., the product structure is advanced, the production is organized in accordance with export standards, and the quality performance reaches the advanced level of similar international products. The working principle of the magnetic crane is made using Faraday's electromagnetic induction principle. The internal use of high-performance permanent magnetic material neodymium borax, can produce a strong suction force in the magnetic circuit, through the handle flip to change the magnetic force line to make the jack in the working or closed state; Without external power supply, it is a new type of lifting tool that is both safe, energy saving and high efficiency. When the jack is in the working state, the lifting surface at the bottom of the jack constitutes a pair of longitudinal magnetic poles, which firmly absorbs the workpiece of the iron material, and there is a V-shaped groove on the bottom surface, so it can absorb both the plate workpiece and the cylindrical workpiece. Therefore, the jack has strict requirements on the thickness and area of the plate. Magnetic crane is widely used in machinery industry, mold manufacturing, warehouses and transportation departments to transport steel plates, steel ingot and other magnetic objects
The use of magnetic crane: 1, lifting, first will be lifted workpiece surface clean, such as rust and convex thorns should be cleaned. The center line of the permanent magnet jack preferably coincides with the center of gravity line of the workpiece, and then the jack is placed on the working plane, and the rotating handle is rotated from the position of "-" to the direction of "+" to the limit pin. Check that the security ramp of the handle is automatically locked, and then lift. 2, when the workpiece is lifted, it is strictly prohibited to overload, strictly prohibited the human body from under the workpiece, the temperature of the suspended workpiece and the ambient temperature are not more than 80 degrees, no violent vibration and impact. 3, after the completion of lifting, press the handle button inward, so that the security key on the handle is separated from the security pin. The handle rotates from "+" to "-" to the limit pin. Keep the jack in the closed state, and the end piece is detached from the jack. 4, lifting the cylindrical workpiece, should keep the B-shaped slot and the workpiece Angle is two straight contact, so its lifting gravity is only 30%-50% of the rated lifting gravity.
