Hammar Hydrostatic Release Unit Green Model HRU for Small Liferafts

Product overview

The Hammar Hydrostatic Release Unit Green Model Small Raft is designed for liferafts from 4 up to 12 persons and outside SOLAS regulations. For liferafts smaller than 4 persons, please contact the liferaft manufacturer or CM Hammar AB. The Hammar H20 for small rafts consists of a double-looped white rope line, a release mechanism and a Red Weak Link with a green lower thimble (breaking strength 1,2 +/- 0,4 kN). The strong white 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 approx. 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. 2 Year Life Servicing Intervals The Hammar H20 needs no annual service, maintenance or spare parts, but MUST BE REPLACED EVERY TWO YEARS. The HRU will be dated marked on dispatch of your purchase and will expire 2 years from this date.
