Concept: A hoist is a device for raising or lowering a load. A lever-operated (ratchet lever) hoist is powered entirely by a person pulling a hand lever, which advances a ratchet-and-pawl mechanism; an electric hoist uses a motor. Each suits different situations, so the "better" choice depends on the application's requirements for power, speed, mobility, and cost.

Why the correct answer is right: The lever hoist's key advantages are portability and suitability for short, manual lifting operations:

• It is compact, light, and self-contained — it needs no electrical supply, so it can be used in the field, at remote sites, at height, or in confined or hazardous (e.g. explosion-risk) areas where running power is impractical.
• It is ideal for occasional, short-duration lifts, tensioning, and positioning work done by hand, where setting up a powered hoist would be unnecessary.

Why the other options are wrong:

• Lower cost and larger load capacity — while a lever hoist does have a lower initial cost, its load capacity is limited (it relies on human effort), so "larger load lifting capacity" is false; electric hoists handle far heavier loads.
• High lifting speed and remote control are strengths of electric hoists, not manual lever hoists, which are slow and operated by hand at the load.
• Continuous operation and automatic overload protection again describe powered/electric hoists; a manual lever hoist cannot run continuously and depends on the operator's judgement rather than automatic protection.
