Installation First, you need to install the chain box; secondly, connect the power cord to connect the power cord must be cut off in advance. Meanwhile ground should be well grounded, otherwise the operator when touching any part of the hoist or chain, are likely to feel a shock feeling. Third, the degree of load chain lubrication chain lubrication chain hoist load chain is an important factor affecting the life. Timely and effective lubrication of the effective life of load chain, in order to ensure the chain. Fourth, check the chain arrangement for multiple-line chains, electric chain hoist, should ensure lower hook frame is not reversed. If you flip, it was restored to normal state, make sure the chain weld and arranged in rows. Do not twist the chain hoist hanging load. Finally traction hoist, check the operating voltage due to electric chain hoist factory, is based on user-specified voltage or high voltage equipment (only dual voltage terms), such as 230 / 460V, need to check wiring and confirm meets supply voltage. If not, refer to the manual must be corrected in order to meet the requirements of the operating voltage. HC large-tonnage electric hoist CD1 electric hoist is a small light lifting equipment, with a compact, light weight, small size, parts versatility, easy operation. Reducers with hard gear surface, long life and high mechanical efficiency. Conic rotor brake motor ring type electric hoist, two-way security has upper and lower limit device. MD electric hoist with double speed and slow two speeds, lifting smooth and accurate. The main structure of the gear unit, running organizations, drum equipment, hook device, coupling, slow drives, flexible cable current electric hoist introducer, limiter, motor with cone rotor motors, set power and braking force in one, it has a small qh hoist electric hoist, light weight, simple operation, easy to use features, industrial and mining enterprises, storage terminals and other places necessary lifting equipment. CD1-type electric hoist can be widely used to hoist heavy objects or installed single-girder cranes straight line, the word beam profile can also be used to hoist double girder, gantry crane or jib cranes, industrial and mining enterprises, railways, docks, warehouses commonly used lifting equipment. HC / HM large tonnage electric hoist: 2 Product Description:. HC, HM-electric hoist draws on international and domestic advanced experiences, introduced by changing the pulley ratio was increased from the weight concept, in the same type on a hoist can be derived from a variety of weight specifications, the series is mainly used for electric hoist from the weight of large, high-level places, such as supporting the hoist double girder, hoist gantry cranes.
