It possesses strong magnetic system which is composed by high- perfomance permanent magnetic materials--ND-Fe-B. By optimizing the magnetic circuit design and the overall steel structure, we made the product smaller, lighter and stronger attraction. The unique magnetic circuit design makes the remanence close to zero. High safety factor makes the max pull force 3.5 times of the rated lifting capacity. At the bottom, the V shape design is used to absorb the corresponding cylindrical objects. Moreover, the handle is designed with safety switch button which can be operated with one hand. It is an ideal tool for factories, warehouses, terminals and transportation industry.
