A chain hoist is a common type of manual hoist used in rigging operations. It operates by using a chain to lift heavy loads, allowing workers to raise and lower items with relative ease and control. The design of a chain hoist typically includes a hand chain that the user pulls to lift the load, using mechanical advantage to minimize the effort required. This makes it suitable for various rigging tasks in different settings, whether in construction, shipping, or manufacturing.

The other options represent hoisting equipment that operates differently. An electric winch, for instance, relies on electricity to move loads and is not manually operated. Hydraulic cranes and pneumatic lifts utilize fluid pressure or compressed air to function, respectively, and can handle much larger loads but are not categorized as manual hoists. Hence, in contexts where manual operation and control are necessary, the chain hoist stands out as the ideal choice for rigging tasks.
