When working with hoists, what does 'left-lay' refer to?

'Left-lay' specifically refers to the direction in which the strands of a rope are twisted. In the context of ropes, 'left-lay' means that the strands are twisted in a counterclockwise direction. This is an important aspect to consider when using hoists because the lay of the rope can affect its performance, handling, and how it interacts with pulleys and sheaves.

Understanding the lay direction is crucial for ensuring that ropes are handled properly during rigging operations. Using ropes with the correct lay can help maintain their integrity and strength, preventing potential failures during lifting tasks. For instance, using a right-lay rope in applications suited for a left-lay rope could lead to issues like kinking or reduced strength when the rope is under tension.

The other options, while relevant to hoisting equipment, do not directly pertain to the concept of 'left-lay.' The type of gear used, weight capacity, and methods of anchoring are all critical factors in rigging and hoisting, but they do not define the specific characteristic of the rope's twist like 'left-lay' does.
