Electric hoist lifting incident analysis

When using electric  rope hoist  lifting occurs during the broken teeth, broken shaft brake failure occurs, conventional electric hoist can play a protective role, accident consequences will be disastrous. In a safe braking torque and brake friction materials made ​​a trial, which will eventually help secure gateway has a very high reliability. Load protection overload protection is common, for some special circumstances, such as electric  lever hoist  for lifting or similar underground gondolas this condition, the required electric hoist crane being lifted can not occur on the rail car stuck or broken rope or fixed rope off phenomenon, it requires a super electric hoist, underrun protection. Electric hoist in cement and other building materials enterprises in the most widely used. Electric hoist mounted on the U-shaped multi-track. The cables are arranged in the middle of the track, the upper beam. Slip ring for the two rings linked together, there is a certain margin in order to avoid cable scratch cards. Put an end cap on the steering ring tightrope, leaving a good motor lead wire fixing rear rubber ring at the lower end of turn.chain block In the traction motor to turn to the center ring, pulling cable in a straight line or circular motion. If the electric hoist hanging objects from the car and run when improper methods, then make hanging objects swing accidents. Hanging objects lifting hoist, wire rope or chain tension when there should be parking, electric hoist according to the direction of the hook again to identify jitter hook, hanging objects should also be checked whether the hanging prison; electric hoist hanging objects runtime. By the person behind the electric hoist hanging objects help steady object and under the command of the rigger run around obstacles; electric hoist the runtime not intermittent,hoist equipment long-distance running, it is best to run a long power transmission.
