What does item "C" refer to in illustration...

🔍 Key Concepts

• Compare the labeled parts: notice how item D includes the hook and sheaves, while item C is located above it on the same set of falls. • Think about what device is used to keep multiple hoist falls evenly spaced and sharing the load equally between them. • Recall that a rider block is a small block that may travel with or guide the main hook block, while an equalizing beam/hoist fall spreader is usually a rigid bar or frame between sets of falls.

💭 Think About

• Look closely at how the wire ropes (falls) connect to item C: is it a rotating block with sheaves, or a rigid member that the ropes pass over/around? • Ask yourself which of the options would logically sit between the hoist block (with the hook) and the boom head to keep the lines separated and the load balanced. • Consider which component would actually carry the hook versus which would only guide or separate the lines attached to the hook block.

✅ Before You Answer

• Verify whether item D already fulfills the function of the main block/hook assembly (hook plus sheaves). • Check if item C has any sheaves (wheels) or if it appears as a solid bar/frame – that will rule out some choices. • Confirm which term among the options is typically used for a rigid member that keeps multiple hoist falls properly spaced or equalized.
