Chain block chain hoist manual portable mini chain hoist 1t 2T 3T 5T

Chain block is a kind of manual hoisting machinery with simple use and convenient carrying, also known as ""chain block"" or ""chain block"". The chain block is suitable for short-distance hoisting of small equipment and goods. The lifting capacity is generally no more than 10t, the maximum can reach 20t, and the lifting height is generally no more than 6m. The shell of chain block is made of high-quality alloy steel, which is firm, wear-resistant and high safety. When the chain block lifts the weight upward, pull the manual chain and chain wheel clockwise to rotate. When descending, pull the hand zipper bar counterclockwise. The brake seat is separated from the brake pad. The ratchet wheel is stationary under the action of the pawl, and the five tooth long shaft drives the lifting sprocket to run in the opposite direction, so as to lower the weight smoothly. The chain block generally adopts ratchet friction plate one-way brake, which can brake automatically under load. The pawl engages with the ratchet under the action of spring to make the brake work safely.

The main parts of the chain block are made of alloy steel, the chain is 800MPa high-strength lifting chain, the material is generally 20m2, medium frequency quenching heat treatment, low wear and anti-corrosion chain; The high-strength hook is generally made of alloy steel. The forged hook design ensures slow lifting to prevent overload; Comply with European CE safety standards.
