What is the most commonly used light lifting device in boiler shop operations?

• A. Hydraulic jack
• B. Chain pulley
• C. Come-along
• D. Chain hoist

Answer: (D)

In boiler shop work, overhead lifting needs to be controllable, safe, and versatile for positioning heavy parts. A chain hoist fits that role best because it offers smooth, controlled lifting and lowering, solid braking to hold a load in place, and easy attachment to overhead beams or trolleys for moving components around the shop. It provides good load capacity with straightforward operation, and it can be used in tight or confined spaces typical of boiler fabrication and maintenance.

Compared with a hydraulic jack, which is great for lifting a single object but isn’t ideal for continual, precise vertical positioning or for traveling along a beam, the chain hoist gives better control and portability. A come-along is lighter and useful for shorter pulls, but it requires more effort and offers less precise control under heavier loads. A chain pulley system increases mechanical advantage but isn’t as practical for frequent overhead lifting and precise positioning as a dedicated chain hoist. For these reasons, the chain hoist is the most commonly used light lifting device in boiler shop operations.
