I. Introduction to permanent magnet lifter:
Permanent magnet lifter: also known as permanent magnet suction lift, magnetic lifting, magnetic lifting, lifting magnet, permanent magnet, etc. It has the characteristics of small volume, stronger holding force, no electricity, almost zero remanence and high safety factor.
Two, the principle of permanent magnet lifter:
The working principle of the permanent magnet hoist is to use Faraday's principle of electromagnetic induction to manufacture. The internal use of high-performance permanent magnetic material neodymium borax, can produce a strong suction in the magnetic circuit, through the handle to change the magnetic field line to make the lifting device in the working or closed state; Without external power supply, it is a safe, energy-saving and efficient new lifting tool.
When the lifting device is in the working state, the lifting surface at the bottom of the lifting device constitutes a pair of longitudinal magnetic poles, the workpiece of the iron material is firmly absorbed, and the bottom surface has a V-shaped slot, so it can both suck and lift the plate workpiece, but also can suck and lift the cylindrical workpiece. Therefore, there are strict requirements for the thickness and area of the plate.
Three, the characteristics of permanent magnet crane:
1, compact structure, compact shape, easy to operate
2, high performance permanent magnetic material, no demagnetization
3, work without the support of electricity or other power
4, advanced scientific magnetic circuit balance design, strong holding force, remanence is almost zero, safe and reliable
5, pull pull force is 3.5 times of rated gravity, high safety factor
6. Using computer simulation magnetic circuit design, the magnetic field distribution is reasonable, and the magnetic penetration depth is large.
7, no need for excitation power supply, no need for cooling system.
8, energy saving, low failure rate.
Simple operation, safe and reliable operation.
10, the technical indicators are in line with JB/T8711-1998 standard.
Four, the use of permanent magnet crane:
1. When lifting, the surface of the workpiece to be lifted should be cleaned, such as rust and bumps should be cleaned. The center line of the permanent magnet lift is best coincides with the center of gravity line of the workpiece, and then the lift is placed on the working plane, and the handle is rotated from the position of "-" to the direction of "+" to the limit pin. Check whether the security diagonal block of the handle is automatically locked, and then lift.
2. When lifting the workpiece, it is strictly prohibited to overload, and the human body is forbidden to pass under the workpiece. The temperature of the lifting workpiece and the ambient temperature are not greater than 80 degrees, without violent vibration and impact.
3. When lifting cylindrical workpiece, the connection Angle of B-shaped groove and workpiece should be kept in contact with two straight lines, so its lifting force is only 30%-49.99% of the rated lifting force.
4. After lifting, press the handle button inward to make the security key on the handle detached from the security pin. Rotate handle from "+" to "-" to limit pin. Make the jack-up in the closed state, and disconnect the work piece from the jack-up.
Five, permanent magnet crane safety notice:
1. In the process of lifting and moving the permanent magnet crane, the collision and hair knocking of the contact surface should be avoided as far as possible, so as not to affect the use performance and life. When idle, the bottom surface is best coated with oil to protect, wipe clean when used.
2. Please read the instruction manual before use and make clear the performance before use. If there is any confusion, please contact the manufacturer to avoid accidents.
3, should often check the flexibility of the parts, keep the use of flexibility.
