3/4" Pulleys and Arborist Blocks

3/4" capacity blocks and pulley are a good choice for serious rigging work that requires high strength rigging ropes and slings. Because of their larger capacity, 3/4" Arborist blocks will accept larger and stronger ropes such as 3/4" Stable Braid. All of the blocks listed below are arborist blocks, designed for applications where shock-loading is possible. For more information on using blocks and pulleys in tree work, check out the Art and Science of Practical Rigging. Click on a picture for a larger image.

Please note that Working Load Limits (WLL) are listed at 10% of the Breaking Strength (Breaking Strength.) This is a safer ratio to use than the 5:1 ratio commonly used for lifting applications, as tree work involves the risk of shock loading, and it is the same ratio used when calculating the Working Load Limit of Arborist Rope.
