The CSR2 Pulley (as the name implies) was specifically designed for confined space rescue or rope access work. It was engineered to enable efficient lowering and raising, and is easy to release under load. It is a heavy-duty pulley featuring machined aluminum swivels at both ends of the system to eliminate potential twisting of lines. These are all highly important attributes in a rescue situation.
This latest version of the CSR2 Pulley is not only stronger than before, but also lighter. It accommodates 7/16 in (11 mm) to 1/2 in (13 mm) life safety rope. The CSR2 uses a proprietary, patented locking system, which eliminates a toothed cam or Prusik so it can easily and safely be released while under load. Ideal for industrial applications as well as many rescue operations.
(The innovative design of this pulley eliminates the toothed cam, which means it can still be released easily, even if the system is fully collapsed and pulled tight. Systems that feature a toothed cam must be raised even more before the cam can be released, which is sometimes difficult or even impossible if the system is fully collapsed, or if the user doesn’t factor in this problem ahead of time. This has the potential to cause problems with the load on the system becoming stuck.)
An essential thrust-bearing swivel reduces torque by aligning the pulley with the load, thereby increasing safety and efficiency. Thanks to its larger size, it easily accomodates use with rescue-size carabiners.
Machined from a solid block of aircraft-grade aluminum, the CSR2 features a top-strength aluminum side plate, sealed bearings and anodized aluminum sheaves. The side becket location allows for maximum lift height and full retraction of the system, and a removable becket cover facilitates changing out lifeline with sewn terminations.
