For use with all Standard and ISO non-SOLAS liferafts.
This Hydrostatic Release Unit is designed to release loads from remote positions up to a distance of 100 meters. The Hammar H20 consists of a double looped white rope line, a release mechanism and a red weak link with a green lower thimble. The weak link system has a breaking strength of 1,2 +- 0,4kN.
The white strong rope of Hammar H20 is secured to the deck or liferaft cradle and attached to the liferaft lashing with a slip hook. If the ship sinks, the water pressure will, within approximately 4 metres, activate a sharp knife, that cuts the white strong rope and the liferaft will float free. As the ship sinks, the liferaft painter line will be stretched and the liferaft starts to inflate. The Red Weak Link breaks and survivors can board the floating liferaft.
The Hammar H20 needs no annual service, maintenance or spare parts, but must be replaced after 2 years of use on a ship.
USCG approval no 160.062/14/10.
Suitable for 4 to 12-man liferafts.
