The R50 Series Unit is a self-retracting lifeline, capable of raising and lowering. for rescue or retrieval. If a worker slips or falls. the unit locks up. arresting the fall. The system can then be activated into winch mode, raising or lowering the worker to safety. The R50 also has a friction brake that prevents the crank handle from free-wheeling while under a load. The unit is manufactured of a rugged. lightweight cast aluminum housing, and includes a mounting bracket for FCP's Tripod or Davit Systems. a #45 split pulley, and carabiner for attaching the lifeline to an anchor such as a tripod. This R50 unit has a 50' TECHNORA SYNTHETIC ROPE.
Characteristics of TECHNORA ROPE:
(1) High tensile strength
The tensile strength of Technora is 28g/de(24.7cn/dtex,350kg/mm2), which is 8 times as strong as steel and 3 times as strong as fiberglass, polyester and nylon of the same weight. This property will serve significantly to reduce weight.
(2) Fatigue resistance
High tenacity fibers generally show a loss of strength against repeated abrasion, flexure and stretch, Technora has excellent fatigue resistance, as compared to the other high tenacity fibers.
(3) Dimensional stability
Technora has a stiff and highly oriented molecular structure which leads to a high modulus, low creep and low stress relaxation. Due to its low thermal shrinkage, it has good dimensional stability.
(4) Heat resistance
Technora has a decomposition temperature of 500 degrees C. It can be used at 200 degrees C for long periods of time and, even at 250 degrees C, it maintains more than half of its tensile strength that was measured at room temperature.
(5) Chemical resistance
Technora exhibits high resistance to both acids, alkalis and organic solvents. It is also resistant to sea water and steam.
