FTC Donut Rigging Pulley
Rigging loads in trees sometimes means implementing complex systems, so your gear must rise to the challenge. The FTC Donut helps you in all situations, no compromise on safety or work flow. From the simplest rigging scenario to the most complex ones, involving several ropes at the same time.
A fusion between a rigging block and a friction ring, the Donut from FTC offers the best of both worlds, separate or combined. Choose to use the sheave to lift or move a load, or the central part for useful friction when rigging. Need both? The FTC Donut will take two ropes simultaneously to help you manage complex situations, i.e. a heavy load or a delicate load transfer.
Friction is a vital element of rigging, especially for dynamic rigging works. It reduces the effort on the cylinder and helps the ground man control the speed of the load during the descent. The increased control contributes to the climber’s safety and that of the team by minimizing the risks linked to abrupt or uncontrolled movements.
FTC Donut Pulley Instructions (PDF)
- Round shape limits wrong positions and reduces risk
- Easy to set up, even between two points.
- The symmetry also allows the use with several slings to adjust its placement with more precision
- It can be used on the ground, as a redirect for instance, or up in the tree
- Great ratio weight/WLL for its category
- A reliable tool, adapted to all constraints yet not over-complicating the work
