Manual hoist as an upgraded version of the fixed pulley

Manual hoist as an upgraded version of the fixed pulley, fully inherits the advantages of fixed pulley, while using a combination of reverse backstop brake reducer and chain pulley blocks,lever hoist manufacturers symmetrically arranged two spur gears turning structure, simple, durable and efficient.
Manual hoist by hands and pull chains, bracelets wheel rotation, the friction plate ratchet, brake pressure into one common rotating seat, the long axis of the tooth will turn the sprocket tooth spline hole short axis and gear. This means lifting sprocket holes on the splines on the drive gear lifting chain, so as to enhance the smooth heavy.wire rope electric hoist Using one-way ratchet friction disc brakes, brake under load on their own, with the ratchet pawl engagement under the action of the spring, the safety brake.

Liftech Equipment Manual Hoist usage rules


Liftech Equipment Manual Hoist stayed overload use is strictly prohibited. Do not operate with a power other than human. Before using the parts required to confirm intact,cargo lashing transmission parts and lifting chain oiled, idling normal. Liftech Equipment Manual Hoist lifting hook before checking whether hanging down firmly, lifting chain should be hung vertically, not a wrong twist of chain link, double under hook rack chain not flip.
Liftech Equipment Manual Hoist operator should stand on the same plane with the bracelet round hands pulled the chain to make bracelets wheel rotates clockwise, you can make the weight rise;small electric hoist reverse hands pulled the chain, the weight can slowly decline. When lifting weights, is prohibited personnel action to do any work or walk under a heavy object, in order to avoid a major accident. In the lifting process, regardless of the weight up or down, drag chain hands, the force should be uniform gentle, do not use too much force, so as not to hand chain jumping or snap ring. When the operator is found hand-pull tension greater than normal, you should immediately stop using it. Prevent damage to the internal structure, to prevent falling objects accident. After heavy to be safe and secure landing,manual lever hoist then remove chain hoists under the hook. Use Liftech Equipment Manual Hoist finished, gently, in a dry, well-ventilated place, apply lubricant put away.

Liftech Equipment Manual Hoist works


Liftech Equipment Manual Hoist as an upgraded version of the fixed pulley, fully inherits the advantages of fixed pulley,electric wire rope hoist while using a combination of reverse backstop brake reducer and chain pulley block, the symmetrical arrangement of two spur gears rotating structure, simple, durable and efficient.
Liftech Equipment Manual Hoist hands by pulling the chain, bracelet wheel rotation, the friction plate ratchet, brake pressure into one common rotating seat, then the long axis of rotation of sprocket teeth, tooth spline hole short axis and gear. This means lifting sprocket holes on the spline drive gear on lifting chain, thereby lifting heavy objects smoothly. Using one-way ratchet brake friction plate,mechanical lifting devices on their own under load brake pawl engagement with the ratchet under the action of the spring, brake safety.

Hoist equipment installed before the transfer operation


Hoist equipment installed before the transfer operation, check the wire rope, clutches, brakes, insurance ratchet,electric chain hoist and trolley drive pulleys, etc., to determine the safety and reliability before operation. Wire rope on the drum must be arranged in neat rows, the job should be retained at least three times. When the job, it was not allowed to cross the wire rope hoist by preventing accidents.
Hoist equipment including motor, hoist, chassis, shields and other components; using three deceleration mode,strong electric winch with spiral pay transmission output torque greater. Hoist steel supporting civil overcome irregularities in order to reduce overall noise and vibration.hoist equipment with hydraulic hoist, winch hoist, doors, hand wheel hoist, hoist flashlight, hand hoist, screw hoist, dual crane hoist and so on.
