Chain Hoist
Chain hoists are typically electrically powered, but can be manually or pneumatically operated as well. In a chain hoist, the chain is attached to a lifting hook on one end and a drum wheel on the other. To lift, the crank turns the reel and wraps the chain around the spool, raising the load at the end of the hook.
Chain hoists offer many benefits. First, metal chains are more durable than rope. In addition to their durability, roller or link chain hoists are popular because they are fairly simple and inexpensive. They also require a low level of maintenance and are able to survive high temperatures without suffering damage.
In industrial settings, chain hoists are most often used to lift items vertically. Chain hoists are available in multiple varieties; they differ by diameter, load capacity, line material, length, and maximum loaded line speed. Choosing the hoist that fits the needed specifications is important, because safety issues can arise if hoists are misused.
