Permanent Magnetic Lifter

Permanent Magnetic Lifter

Product Overview

A permanent magnetic lifter (also known as a permanent magnetic lifter, magnetic hoist, or permanent magnetic chuck) is a lifting device that uses high-performance permanent magnetic materials to generate holding force, enabling the lifting of ferromagnetic workpieces without an external power supply. By turning the handle, the internal magnetic circuit is changed to achieve pickup and release. Features include compact size, light weight, strong holding force, no power consumption, near-zero residual magnetism, and a high safety factor. It is widely used in industries such as steel, machinery manufacturing, mold making, shipbuilding, and warehouse handling.

Core Advantages

• No Power Required: Uses high-performance NdFeB permanent magnetic materials — zero energy consumption, zero operating cost

• Safe & Reliable: Pull-off force is 3.5 times the rated lifting capacity — high safety factor — near-zero residual magnetism

• Simple Operation: Rotate the handle to pick up and release — no professional training required

• Compact & Lightweight: Small size, light weight — easy to carry and operate

• No Demagnetization: Stable magnetic performance — no loss of magnetism over years of use

• Strong Versatility: Can lift flat plates as well as cylindrical workpieces using V-shaped grooves

• Maintenance-Free: No moving parts to wear out — no regular maintenance required

Operating Precautions

1. The surface of the workpiece should be clean, free of rust scale and burrs

2. Do not exceed the rated lifting capacity

3. Workpiece temperature and ambient temperature should not exceed 80°C

4. When lifting cylindrical workpieces, the lifting capacity is only 30%–50% of the rated capacity

5. Do not allow personnel to pass under the lifted workpiece

Typical Applications

Lifting and handling of ferromagnetic workpieces such as steel plates, section steel, steel ingots, molds, cast iron parts, and cylindrical steel materials.
