CD / MD-type electric hoist mainly consists of three parts, one for the lifting mechanism, two wire rope hoist 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 panels and run institutions connected to both ends of the hoisting reducer, motor connected to the supply wire rope hoist, under the joint work by the rope and hook device, before the top of the housing, installation limited locator guide rod device. 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 push-button switch in the direction shown symbols correctly push button electric wire rope hoist, electrical control box by closing and opening, you can control the action gourd. Installation Notes 1. The wire rope hoist line to ensure the hoist to the ends do not damage the body or prevent derailment wire rope hoist quality, should be set at both ends of the elastic buffer in orbit; should be set on the track or frame 2. connection grounding wire, grounding wire available 4-5mm of bare copper wire or metal wire cross-section of not less than 25mm; and 3. All electrical circuits of electrical installations, control loop resistance must not be less than the minimum operating voltage of 1.5 volts per Euro wire rope hoist | Electric wire rope Hebei Gourd | Xinyu Xinyu lifting provided by Crane Co.
