How does a hoist chain differ from a sling chain?

The distinction between a hoist chain and a sling chain is fundamentally based on their design and intended use in lifting operations. A hoist chain is specifically engineered to be reeved, or threaded, into a hoisting mechanism, such as a chain hoist. This design allows it to effectively lift loads vertically, providing the mechanical advantage needed for heavy lifting.

In contrast, a sling chain is typically utilized to wrap around the load being lifted. Its purpose is to secure and stabilize the load during transportation and lifting. Unlike a hoist chain, it does not engage directly with the lifting mechanism but rather connects to it to help distribute the weight of the load.

Therefore, the correct choice highlights how the hoist chain's integration into the lifting mechanism distinguishes it from the sling chain, which is employed to encircle and secure the load. Understanding this difference helps ensure safe rigging and lifting practices in various industrial settings.
