Permanent Magnetic Lifter 20150318

Permanent Magnet Manufacturer China Rare Earth Magnet Limited 

Classified into manual and automatic types, permanent magnetic lifters made of neodymium magnet materials have smaller sizes, lighter weight, stronger attraction, special magnetic circuits and residual magnetism at almost zero. With high safe factor, the maximum pull-out force is as 2.8-4 times as rated lifting power. There is a safe button attached to the handle switch of manual magnetic lifters, which can be operated by one hand. Automatic permanent magnetic lifters do need to flip the handles manually but depend on attraction of zoom-control of electric hoists’ lifting hook. Using no electricity, they can safely lift up round steels and steel plates, which are widely applied to lifting and installation of steels, machinery components and various molds. Also, they can be used in shipbuilding, engineering machinery and automobiles, which improve working condition of load and unload and enhance working efficiency.

Features
1. Small structures, compact shapes and easy operation
2. High-performance permanent magnetic materials , never demagnetized
3. Needing no electricity or other power to support working
4. Advanced and scientific magnetic circuit designs, strong attraction, residual magnetism almost at zero, safe and reliable
5. High safety factor, the maximum pull-out force is as 3.5 times as rated lifting power.

Applicable range
Permanent magnetic lifters are applicable to transport steel plates, iron blocks and cylinders, such as machinery components, press dies and diversified steel materials. These permanent magnetic lifters are lifting equipments without electricity supply. With developed structures, the quality can reach advanced level of similar products in the world. Magnetic lifters are widely applied to machinery, molding manufacturing industry and transportation.

Advantages 
1. Permanent magnetic lifters adopt computers to simulate magnetic circuit designs with reasonable distribution of magnetic field and deep magnetic permeability.
2. Structures of magnetic lifters are simpler than that of iron separator and they need no electricity supply and cooling system.
3. They can save energy and have low failure rate.
4. They are easy to operate, safe and reliable.

Structure
Strong magnetic system of permanent magnetic lifters is made of high-performance of neodymium permanent magnetic materials. There are rings on the top of the lifters and V-shaped groove at the bottom for attracting cylinder objects. Neodymium permanent magnets are magnetic source, which has no power supply, strong attraction and low residual magnetism.

Working theory
Permanent magnetic lifters makes use of Faraday’s principle of electromagnetic induction, in which neodymium can produce strong attraction. Through flipping handles, the lifters can be turned on or off. They can work without power supply, which are safe and high-efficient new-type magnetic lifters.
