Individual Mechanical Advantage System (iMAS)

Rapid Problem Solver for Vertical Rescue

The Individual Mechanical Advantage System, iMAS, is a compact grab & go piggy back mechanical advantage system designed for operators who need fast, reliable solutions in complex vertical environments. Rescue technicians, military operators, and mountain teams use the iMAS for rapid pick offs, stretcher raises and lowers, and anchor transitions where speed and control matter. The system handles traditional hauling ratios including 3:1, 4:1, 5:1, and 9:1, giving riggers the flexibility to reduce force or increase travel as the scenario demands. Lightweight and small enough to ride on a pack or attach to an aid bag, the iMAS is intended to convert difficult rigging problems into manageable, repeatable operations.

Purpose Built Mechanics and Guided Tensioning

Engineered around a guided line tensioning system and a 6mm XTEC cord rated MBS 4,721 lb, 21.0 kN, the iMAS optimizes rope management and load control for a wide range of rigging tasks. Its configuration supports system knot passing, adjustable change of directions and artificial high directionals, plus rig to raise and rig to lower anchor transitions without extensive re rigging. The design lets a single operator or a team control litter angle and attendant positioning while maintaining predictable mechanical advantage, which reduces fatigue and increases precision during extended operations.

Field Durable Construction and Reliability

Built for repeated field use, the iMAS marries robust cord performance with rugged hardware geometry to resist abrasion and maintain smooth operation under load. The 6mm XTEC cord provides a high strength to weight ratio with a verified MBS of 4,721 lb, supporting demanding technical rescue tasks. At just 4.25 lb and compact dimensions, H 7 in. x W 4.5 in. x D 2.75 in., the system balances durability with portability so teams can rely on consistent mechanical advantage day after day. Components are designed for predictable handling and easy maintenance in austere conditions, reducing downtime between missions.

Multi Mission Versatility Across Environments

The iMAS adapts to urban, industrial, and mountain environments, making it a versatile choice for search and rescue, tactical extraction, and wilderness evacuations. Use it for individual and team pick offs, back tie anchor tensioning, vertical litter angle adjustment, and attendant positioning in confined or open terrain. Its ability to create adjustable redirects and artificial high directionals means fewer anchors and quicker setup in technical scenarios. Lightweight packing and simple rigging logic allow rapid deployment from bags, packs, or vehicle kits, keeping teams agile across mission sets and environmental conditions.
