1.General description:
manual chain block is a simple use, easy to carry the manual lifting equipments. Chain block also called chain hoist or chain, suitable for small equipment and cargo lifting within short distance. Normally chain block lifting capacity: 0.25~25tons,lifting height is 3~6m. Chain block with the features of safety and reliability, easy maintenance, high mechanical efficiency, bracelet pull small, lighter weight and easy to carry, beautiful appearance, small size and durable.
2.Specific details of manual chain block :
Gear Case and Hand Wheel Cover Resistant to External Shocks:Both sides of the hoist are covered with a thick steel gear case, and with a strengthened wheel cover. They have an ideal shape and rigidity to maintain bearing alignment and withstand external shock.
Double Enclosure to Keep Out Rainwater and Dust:The braking mechanism, which makes up heart of the hoist, is enclosed in a double
Cover: the wheel and the brake covers. These protective covers not only keep out weather elements but also help to prevent mud and dust from entering internal mechanisms. Hand chain guide attached to the wheel cover provides durability and smooth operation of a hand chain on a hand chain wheel.
Double Pawl Spring Mechanism to Further Increase of Sureness:In case one of Pawl spring is damaged, the other maintains its functions. This mechanism further increases sureness.
Sure and Reliable Mechanical Brake:The dry type asbestos-free Mechanical Brake ensures strong brake performance.
Hooks for Easy Work: Specially heat treated top and bottom hooks have enough strength and toughness for hard job. The design of the bottom hook, with relatively large dimensions, makes it easy to stabilize a load in proper position.
Bearing Mechanism to Increase Mechanical Efficiency:Use of ball and needle bearings remarkably increases mechanical efficiency and produces high output power with minimum manual input.
Load Chain Guide Mechanism:Chain guide mechanism in flanged load sheave and guide roller facilitate smooth movement of the load chain.
Stopper Prevents Excessive Lowering:Stopper assembly prevents excessive lowering of a load and also keeps load chain from exiting if over lowered. When you feel a noticeable increase in pull force to lower the load, you may realize that you cannot lower the load any further.
Ultra Strong Load Chain (Nickel plated):Load chains, the component comprising the heart of the chain hoist, are made of an exclusively developed, heat treated special steel alloy.
