What material is the hand chain hoist lifting chain made of?

Hand chain hoist chains generally have smaller specifications. The diameter of the general bar is less than 10mm, and the material is 20Mn2. In addition to the hoist chain, the main products of round Chain Rigging are high-strength chains, the materials are 25MnV, 23MnNimocr54, and the specifications are Φ5mm-Φ72mm. Mining chains , lifting chain, boiler slag chain, elevator chain, strapping chain.

Structure and composition

It is suitable for short-distance lifting of small equipment and cargo. The lifting capacity generally does not exceed 10T, and the maximum can reach 20T. The lifting height generally does not exceed 6m. The shell of the hand Chain Hoist is made of high-quality alloy steel, which is strong and wear-resistant and has high safety performance. When the hand chain hoist lifts a heavy object upwards, it pulls the manual chain clockwise and the hand chain wheel rotates. When it descends, it pulls the hand chain counterclockwise. The brake seat is separated from the brake pad, and the ratchet wheel is stationary under the action of the pawl.

The five-tooth long shaft drives the lifting sprocket to run in the opposite direction, thus lowering the heavy object smoothly. Hand chain hoists generally use ratchet friction plate one-way brakes, which can brake themselves under load. The pawl engages with the ratchet under the action of the spring, making the brake work safely.

It has the characteristics of safety, reliability, easy maintenance, high mechanical efficiency, small bracelet pulling force, light weight and easy to carry, beautiful appearance, small size, and durability. It is suitable for use in factories, mines, construction sites, docks, shipyards, warehouses, etc. It shows its superiority when installing machines and lifting goods, especially for open-air and non-power supply operations.

The main parts of the hand chain hoist are made of alloy steel. The chain is made of 800Mpa high-strength lifting chain, generally made of 20M2, medium-frequency quenching heat treatment, low wear and anti-corrosion chain; the high-strength hook is generally made of alloy steel, forged The striking hook design ensures slow lifting to prevent overloading; it complies with European CE safety standards.
