Manual chain hoist uses a high-quality alloy steel chain with red oxidation treatment on the surface, which provides additional protection against corrosion and dust. It is durable and anti-aging. You can trust it to lift. The gear system requires almost no maintenance. The closed design can protect the internal parts of this lever chain hoist from dust and pollution. The manual hoist uses load distribution gears to make lifting loads easy. Equipped with two heavy-duty steel hooks with safety latches, it can rotate 360° without twisting and bending. The lifting capacity is sufficient for most industrial applications and is widely used in shipbuilding, power stations, transportation, construction, warehouses, etc.
