What are the components of a typical chain hoist?

• A. The chain, hydraulic pump, and pulleys
• B. The chain, hook, load hook, and gearing mechanism
• C. The motor, control panel, and cable
• D. The weight, hook, and safety latch

Answer: (B)

A typical chain hoist primarily consists of the chain, hook, load hook, and gearing mechanism. The chain is crucial as it is what lifts the load, connecting the hoist to the load being lifted. The hook provides a secure attachment point for the load. The load hook is designed specifically to support the weight safely, often featuring a safety latch to ensure the load does not slip off during lifting.

The gearing mechanism is essential as it allows the operator to lift heavy loads with relative ease by engaging the chain to convert manual effort into lifting power. Together, these components ensure smooth operation and safety during the lifting process, making them integral to the functionality of a chain hoist.

Other choices include components that do not accurately represent a chain hoist. For instance, hydraulic pumps and pulleys are not standard elements in a chain hoist, which operates mechanically rather than hydraulically. Similarly, components like motors and control panels pertain more to electric hoists rather than manual chain hoists. Lastly, while weights and safety latches are important for certain lifting systems, they are not part of the typical assembly of a chain hoist.
