Permanent Magnetic Lifter

I. Permanent Magnetic Lifter – Introduction

Permanent magnetic lifter, also known as permanent magnetic lifter, magnetic lifter, magnetic hoist, lifting magnet, permanent lifting magnet, etc. Features include compact size, strong holding force, no power consumption, near-zero residual magnetism, and a high safety factor.

II. Permanent Magnetic Lifter – Working Principle

The working principle of the permanent magnetic lifter is based on Faraday's law of electromagnetic induction. It uses high-performance permanent magnetic material (Neodymium-Iron-Boron, NdFeB) to generate strong magnetic attraction within the magnetic circuit. By turning the handle, the magnetic flux path is changed, switching the lifter between working (on) and non-working (off) states. No external power supply is required, making it a safe, energy-saving, and highly efficient new type of lifting tool.

When the lifter is in working state, the suction surface at the bottom forms a pair of longitudinal magnetic poles, firmly holding ferromagnetic workpieces. V-shaped grooves on the bottom surface allow lifting of both flat and cylindrical workpieces. Therefore, the lifter has strict requirements regarding the thickness and area of the plate being lifted.

IV. Permanent Magnetic Lifter – Operating Instructions

1. Before lifting: Clean the surface of the workpiece to be lifted. Remove any rust scale or burrs. The centerline of the permanent magnetic lifter should preferably align with the center of gravity of the workpiece. Place the lifter on the workpiece surface. Turn the handle from the "-" position to the "+" position until it reaches the stop pin. Check whether the safety locking block on the handle is automatically engaged, then proceed with lifting.

2. During lifting: Do not exceed the rated capacity. Do not allow personnel to pass under the lifted workpiece. The temperature of the workpiece being lifted and the ambient temperature should not exceed 80°C. Avoid severe vibration and impact.

3. Lifting cylindrical workpieces: Ensure that the V-shaped groove makes contact with the workpiece along two lines. The lifting capacity is only 30% to 50% of the rated capacity.

4. After lifting: Press the button on the handle to disengage the safety lock from the safety pin. Turn the handle from the "+" position to the "-" position until it reaches the stop pin, switching the lifter to the off state. The workpiece will then detach from the lifter.

V. Permanent Magnetic Lifter – Safety Precautions

1. During use, avoid impact or scratching of the contact surfaces, as this may affect performance and service life. When not in use, it is best to apply oil to the bottom surface for protection, and wipe it clean before use.

2. Please read the instruction manual before use. Ensure you understand the operating procedures before operating the lifter. If you have any questions, contact the manufacturer for clarification to avoid accidents.

3. Regularly inspect the flexibility of all components to ensure smooth operation during use.
