20t low headroom electric hoist double lifting point electric hoist manufacturer lifting electric hoist wire rope electric hoist is a kind of small lifting equipment, wire rope electric hoist has compact structure, light weight, small size, strong parts versatility, easy operation and other advantages, it can be installed separately on I-beam, or can also be installed on electric or manual single beam, double beam, cantilever, gantry and other cranes. The motor generally uses a conical motor, which automatically locks and closes the lock after stopping. The supporting wire ropes include phosphated coated wire rope, galvanized wire rope, and smooth steel wire rope. 02CD1, MD1 series wire rope electric hoist is an improved product based on the original CD and MD models. It has the characteristics of compact structure, light weight, large degree of universality of parts, strong interchangeability, high single lifting capacity, convenient maintenance, etc., and is a popular light lifting equipment for current use. The hoist has two categories: fixed type and trolley type, and the fixed type is divided into “A1, A2, A3, A4,” four types, see Figure 3, which can be directly installed on the frame; the trolley type has the function of running and can be installed on the track; the CD1 type is single-speed lifting, and the MD1 type is normal speed and slow speed lifting. Our factory mainly produces electric hoists with a load capacity of 0.25t ~ 20t and a lifting height of 3m ~ 30m. We can also design and manufacture non-series electric hoists according to your needs. The reducers all use helical gear three-stage deceleration. Gears and shafts are made of alloy structural steel or carbon steel, and are heat treated appropriately to ensure their reliability and longevity. The box body and cover are made of cast iron, with good vibration damping and reliable sealing. When the lifting height H = 6m, a claw coupling is used to connect the motor shaft and the input shaft of the reducer. When H≥9m, an intermediate shaft and a steel coupling are added. When H≥18m, the rigidity of the middle shaft of the support frame is matched to ensure the rotation balance. Inspection and preparation before installation a) After the electric hoist is delivered to the installation site, accept it according to the packing slip, and carefully check whether there are any damage or lost parts during transportation; b) Read the instruction manual and other random documents carefully to understand the structure of this product. c) The operating trolley, power inlet and hook device (except 10t) are generally disassembled and packed with the main unit and must be reassembled during installation; d) remove the oil or anti-rust oil on the tread of the electric trolley; e) Lubricate the lifting and running reducer according to the provisions of Tables 8 and 11 of this manual, and seal the refueling hole to prevent leakage. f) Understand the installation site and prepare the installation facilities.
