Shaft Collar under hook lifting gear shaft hoists Structural principle: a combination of speed reducer and chain pulley block with reverse brake check. Chain hoists are obtained to match the load by means of a linear traction human lever handle lever principle, a clamp body rotation movement of the load acting on the inside, driving load operation. First start lifting motor, the starting weights rise appropriate height, the weight of the motor and then start running to the designated location, run the car at the lower edge of the single-beam beam walk. Using a motor-driven wheels to run on both sides of the car when walking. Because walking speed is relatively small, so running the car is generally no braking mechanism. Run the car when walking, in order to prevent heavy fall on lifting mechanism set up an electromagnetic brake. Braking is to rely on spring pressure to the inner and outer disk compression brand chain hoists, the principle is similar to the friction clutch, when the solenoid is energized after release suck utilize leaving the outer disk, external disk release. Electromagnetic brake circuit in parallel with the lifting of the motor circuit, so as long as a start lifting hoist motor, electromagnetic brake is released, so that the weight and lower the lift freely; when the motor is turned off, the electromagnetic brakes are de-energized, the electromagnetic attraction disappeared, under pressure of the spring, and external disk tightly pressed, play braking effect. When lifting hoists goods increased beyond the limit in order to prevent accidents caused by the position of the hoist, the general rise in the lower reel fitted stopper. When the load is increased to the limit position the brand chain hoists, plate and limit switch contact, turn off the power, stop the weight continues to rise. Limiter is to prevent the hanging Jun sometimes rises above the limit position of use, it is not often used. hoist | Hoist | Qingyuan Xinyu Xinyu lifting by Crane Co. provided.
