CD / MD-type electric hoist is mainly composed of three parts wire rope hoist, one for the lifting mechanism, two run institutions, three for electrical installations. 1. The lifting mechanism by lifting the motor through the coupling via subtractor hollow shaft drive spool rotates, so that the rope wrapped around the drum drive hook device up or down. * Lifting motor uses large conical rotor motor starting torque to accommodate frequent product intermittent work started directly. Lifting motor, there are two, ZD is single speed motor; ZDS type of two-speed motors. ZDS motors than normal speed and slow it was 10: 1 * three helical gear reducers are used to slow down. Gears and shafts made of alloy structure processing, and ensuring the reliability and longevity through proper heat treatment; box, cover made of cast iron, the vibration is good, reliable sealing. * High-speed reels made of cast iron or steel seamless pipe manufacture, use spline transmission of power; the drum shell casing of welded steel plate. Reed gourd drum unit is the central part of the side and run wire rope hoist mechanism connected to the supply of both ends of the hoisting reducer connected to the motor, under the rope with a hook device through joint work quality wire rope hoist, housing before the top, installation guide rod locator device is limited. Using special steel forging hook hook crafted and connected by hook beam and shell with thrust ball bearings, so that the hook operate freely, ≤5t hook device is a single pulley, 10t double pulley. 2. Run the mechanism for an electric car, motor running, running reducer, driven trolley common components run institutions. Run agency for reciprocating movement driven by the host device side and reel. Its operating speed is generally 20m / min, can also choose 30 m / min. ≤5t for a drive, ≥10t using two drives. When used with a box beam or H-type supporting the use of the wheel tread for straight, for I-beam, steel wheel surface is rounded. 3. electrical installations hoist electrical installations by electrical control box, push button switch, limiter and connecting wires and other components. Operating voltage pushbutton switch is generally 36V, according to the direction shown by the symbol on the button switch wire rope hoist spot, pressing the right button, by controlling the electrical box and pull off, you can control the action gourd. Electric wire rope hoist brake failure Solution Solution: To solve the problem of loosening the M6, fastening bolts alone is not enough, so we use anaerobic cement ZY-802 anti-loose approach, will hoist the right conical rotor apart, remove the screws, washed with acetone screws, screw, screw, screw holes were painted ZY-802 anaerobic and screw into, wipe the excess glue, paste can be dry after use. Preventive and control solutions for wire rope hoist brake failure, and allows us to reduce losses in the production of which, produce safer, Xinyu electric hoist manufacturers welcome you to visit. Wholesale wire rope hoist, lifting Xinyu (certified), Shanxi wire rope hoist is provided by Crane Co. Qingyuan Xinyu. Qingyuan Xinyu Crane Co.
