Product Description

Hand hoist is a kind of manual lifting machinery which is simple to use and convenient to carry. The hoist is suitable for short distance lifting of small equipment and goods, the lifting weight is generally not more than 10T, the maximum can reach 20T, and the lifting height is generally not more than 6 meters. The shell material of the hand hoist is high quality alloy steel, strong and wear-resistant, and high safety performance. When the hand hoist lifts the weight, clockwise pull the manual chain, the hand sprocket rotation, counterclockwise pull the chain, the brake seat is separated from the brake pad, the ratchet is stationary under the action of the ratchet claw, and the five-tooth long shaft drives the lifting sprocket to run in the opposite direction, so as to smoothly drop the weight. The hand hoist generally adopts ratchet friction vane unidirectional brake, which can brake itself under load. The pawl engages with the ratchet under the action of the spring to make the brake work safely. Hand hoist has the characteristics of safe and reliable, easy maintenance, high mechanical efficiency, low tension of the bracelet, lighter weight to carry, beautiful appearance and small size, durable, suitable for factories, mines, construction sites, docks, shipyards, warehouses, etc. used as installation machines, lifting goods, especially for open air and no power operations, but also shows its advantages. The main parts of the hand hoist are made of alloy steel materials, and the chain uses 800 mpa high-strength lifting chain. The material is generally 20M2, and the chain is of medium frequency quenching heat treatment, low wear and anti-corrosion. High strength hook, generally made of alloy steel, calcined hook design ensures slow lifting to prevent overload; In line with the European CE safety standard.
