What type of knot or hitch can be used for lifting a length of small-bore pipe vertically?

The clove hitch is a suitable choice for lifting a length of small-bore pipe vertically due to its design, which secures the pipe firmly while allowing for quick adjustments. This knot consists of two half-hitches that create a secure grip around the object being lifted. When properly tied, it holds the pipe in place and is particularly effective for cylindrical objects, making it an ideal choice for small-bore pipes.

The clove hitch is advantageous because it can be easily undone after the lift and is straightforward to tie, even in various weather conditions or limited visibility. Its use in lifting applications is common among pipefitters and other trades that require safe handling of round items.

Understanding the characteristics of the other knots is useful as well. While the bowline creates a fixed loop at the end of a rope, it is less suitable for securing objects like pipes directly. The granny knot, known for its tendency to slip, does not provide the secure hold needed for safe lifting. The sheepshank, although useful for shortening a rope, does not adequately secure items for lifting purposes. Hence, the clove hitch's properties make it the best choice for this specific application.
