Helicopter Rescue Equipment – Rescue Harness Mk 4

The IrvinGQ Helicopter Rescue Harness Mk 4 is provided for use when lowering a crew member to assist in the rescue of survivors. When in use, it is fitted to the crew member and connected to the winch cable hook, via a Quick Release Fitting. It is normally used in conjunction with the rescue strop, in which the survivor is hoisted up to the aircraft securely and safely. It can be supplied in configurations to suit specific helicopter types and operating procedures.


It consists of four main components:

  • Harness Assembly – A canvas bucket seat fitted with integral, adjustable body and leg straps.
  • Suspension Strop – A short strap to attach the harness to the helicopter winch cable hook.
  • Quick Release Fitting – Connects the suspension strop to the harness.
  • Extension Strop – A 1.8 m (72 in) strap to use as an additional connecting line between the harness and the helicopter winch cable hook. The Helicopter Rescue Harness Mk 4 is normally used in conjunction with the Helicopter Rescue Strop.
