QUADRA rescue life-lining and back-up device has four different functions:
- Life-lining – controlling a safety line attached to a rescuer
- Lowering – remotely controlling a load
- Hauling – self-locking load raising
- Descending – self lowering of operator
Operator is able to change from one function to another instantly, while rope is loaded and without adding additional components.
Patented double-braking mechanism increases friction under heavy loading and reduces rate at which friction is released.
Folding handle design prevents accidental operation due to interference or poor rigging.
Inspection and cleaning is simple as all component parts of device are visible and accessible.
QUADRA is rated at 200 kg making it suitable for most rescue applications. It also has capacity to arrest a 250 kg load at fall factor 1/3 without damage to rope and retaining full function. All load bearing components are stainless steel for corrosion resistance and reduced spark hazard.
Updated versions have improved threading and durability without changing performance or method operation.
It has been developed with and is extensively used by UK Fire Services and other industrial rescue teams. heightec has a dedicated range of rescue products for use by fire services and rescue teams:
