Hot Sale Fixed Electric Wire Rope Hoist
The crane has carried out a number of technical innovation and optimization design on the original basis to improve the performance, safety and reliability of the crane. Through the detailed analysis of the main components of the crane, the working principle and advantages are expounded, which provides a useful reference for the development and application of similar products.
- Product Introduction
What is the working principle of electric hoist?
Electric hoist has wire rope hoist and chain hoist, and there are divided into fast and low speed. The slow speed type is often used to lift the alloy liquid casting or casting mold and sand box. The lifting mechanism of the wire rope electric hoist is driven by the motor to complete the lifting action of the wire rope reel.
The electric hoist is installed on the I-steel track with a certain span and height, which constitutes the electric monorail crane. The type and span of I-beam vary according to the lifting weight of electric hoist.
Electric hoist is composed of electromagnetic brake, lifting motor, hook, drum and wire rope, gear changing mechanism. The motor usually adopts a three-phase conical rotor motor with a conical brake or a side magnetic circuit motor to provide the driving force of hoist lifting or horizontal movement. A switch box with lifting and walking buttons is mounted on the lower part of the suspension cable for ground control. The motor mounted at one end of the drum is connected by an elastic coupling to a reduction gear mounted at the other end of the drum.
Power electric motor, the rotor shaft magnetic effect, to overcome the pressure of the spring, make its move to the left, fixed on the rotor shaft conical brake and motor end cover after the release, the rotor under the action of the spring, even the coaxial taper on the brake to the right, and the motor end cover after close contact, will produce the friction torque of the motor stop.
