Features: Widely used in machining, mold manufacturing, and other industries; using high-performance permanent magnet materials, strong retention, unique circuit design permanent lifting wholesale, remanence is almost zero; safety factor, the maximum pull-off force Rated gravity is 3.5 times; switch handle security button permanent lifting, one-handed operation more convenient and safe;. Jack bottom "V" groove design quality permanent lifting, lifting the corresponding bar, plate; no electricity, magnetic long-lasting, safer, and in field operations. PM sucker superposition principle is the principle of continuity of flux and magnetic field design of permanent lifting prices, permanent magnet sucker circuit design into a plurality of magnetic system, by the relative movement of the magnetic system to realize the work the pole faces the sum of the magnetic field strength or destructively, so as to achieve the purpose of holding and unloading. Permanent lifting wholesale, Xinyu lifting, Hubei permanent lifting by the Qingyuan Xinyu Lifting Limited.
