CMC Rescue CSR2 Pulley System: Worth Another Look

The CMC Rescue CSR2 Pulley System represents a significant advancement in efficiency and reliability for confined space rescue and rope access operations. Its patented locking mechanism and cutting-edge design make it an exceptional choice for lowering and raising heavy loads in demanding environments. With UL Classification to NFPA 1983 (2017 ED) for General Use, the CSR2 Pulley System is built to handle the toughest challenges.

Innovative Features of the CSR2 Pulley System

The CSR2 Pulley System is unlike traditional pulley systems, offering unique features that enhance performance and safety:

Patented Locking Mechanism:
The CSR2’s locking mechanism is a game-changer. Unlike traditional toothed cams, the CSR2 uses a one-directional bearing, eliminating abrasive contact with the rope. This reduces wear and tear, ensuring durability and safety during operations.
Side Becket Design:
The CSR2’s side-mounted becket provides full compression, allowing for maximum clearance and height in tight spaces. The becket is removable, enabling easy rope replacement with sewn terminations for added convenience.
Machined Aluminum Construction:
Made from high-grade aluminum, the CSR2 pulleys are lighter yet stronger, ensuring optimal performance under load. Swivels at both ends eliminate rope twisting, further enhancing the system’s reliability.

Key Specifications

Locking Ratio: 4:1 system providing 50 feet of draw with 200 feet of rope.
Strength Ratings:
- CSR2 Pulley: MBS 46 kN (10,341 lbf)
- CSR2 Double Pulley: MBS 45 kN (10,116 lbf)
- ProSeries Aluminum Screw-Lock Carabiners: MBS 47 kN (10,566 lbf)
Compatibility: Available with either 11 mm (7/16 in) or 12.5 mm (1/2 in) Static-Pro Lifeline.
Accessories: Includes a 5 ft nylon accessory cord for remote locking mechanism control.

Performance in Confined Space and Technical Rescues

The CSR2 Pulley System is a versatile solution for both confined space entry and rope access work. Its ability to seamlessly transition between lowering and raising operations simplifies rigging and saves critical time during rescues. The system’s high efficiency and minimal rope movement make it an excellent choice for applications where safety and precision are paramount.

In a practical setup, the CSR2 Pulley System excels in achieving height clearance and ensuring smooth, responsive operation. The locking mechanism activates immediately, providing instant security without the need for resets or adjustments.

Gear Included in the CSR2 Pulley System

200 ft Rope: Offers a 50 ft extension for the 4:1 system.
ProSeries® Aluminum Screw-Lock Carabiners: Engineered for strength and durability.
Accessory Cord: Allows remote control of the locking mechanism.

Why Choose the CSR2 Pulley System?

The CSR2 Pulley System simplifies on-scene rigging, reduces components, and enhances safety. Whether you’re working in confined spaces or managing technical rescues, this system provides the reliability and functionality you need to perform efficiently and effectively.
