Usage Instructions

The 8:1 Haul System is designed for fast and efficient setup. Attach the upper pulley to a secure anchor using a large steel or aluminum locking carabiner. To raise a load, pull on the tail end of the rope while the cam automatically locks the rope in place. For lowering, use the accessory cord to release the cam. The system can also be used in "piggyback" configurations for more complex rigging setups.

Applications

• Rescue Operations: Safe and efficient lifting and lowering of patients or equipment.
• Industrial Rigging: Moving heavy loads with reduced effort.
• Rope Access: Enhancing efficiency in ascent and descent tasks.
• Utility and Arborist Work: Lifting and positioning heavy gear and materials.

The CMI 8:1 Haul System is a rugged and reliable solution for rescue and rigging professionals who require superior mechanical advantage and dependable performance. Its lightweight construction and easy handling make it a must-have for critical operations.
