RiggingPro grade

The Teufelberger Sirius 20mm bull rope is a heavy rigging line for removals where you are lowering big wood through a block and lowering device. At about 3/4 inch, it is sized for the loads a crew sees when spars and large limbs come down.

When you need a bull rope

Lowering lines get sized to the wood. When the job is dropping big tops, heavy limbs or spar sections into a block, a 1/2 or 5/8 inch line runs out of margin quickly. A 20 mm bull rope gives the crew the strength and the hand they need to catch and control those loads with a friction device at the base.

Thicker rope also wears better over hundreds of cycles through a block, and it is easier for the ground person to hold and run under tension.

A bull rope also gives the ground crew more control. With the right number of wraps on the lowering device, they can let a heavy piece run and then stop it smoothly, instead of fighting a thin line that bites into their gloves.

Rigging safely with it

Plan every rig from the forces, not the weight of the piece. A dropped load can shock a system with several times its weight. Check that every component, from sling and block to lowering device and anchor tree, is rated for the job, and keep the rope within its working load limit.

Inspect the rope before each job for cuts, glazing, crushed sections and core damage, and retire it if in doubt. Store it clean and dry in a bag. Compare other rigging rope options for lighter work.
