Question 645Deck General70% to pass
What does item "C" refer to in illustration D045DG of a 30-ton pedestal crane?
AI Explanation
The correct answer is C) Rider block.
The rider block is a component of a pedestal crane that allows for the hoist rope or cable to pass through and change direction, enabling the crane to lift and move loads. It is a critical part of the crane's rigging system and is responsible for smoothly guiding the hoist line to the load.
The other answer choices are not correct because:
A) The block/hook assembly refers to the hook and sheave block at the end of the hoist line, not the rider block.
B) The equalizing beam is a different component that distributes the load evenly across multiple hoist lines.
D) The hoist fall spreader is not a component typically found on a pedestal crane.
