Hammar H20 for Small Rafts HRU

A vessel can sink very quickly and it is important that a Hydrostatic Release Unit (HRU) is attached to the lashing of a fitted liferaft allowing it to launch automatically if there isn't enough time, or it is not possible, to launch it manually.

The Hammar H20 for Small Rafts HRU is designed for liferafts from 4 up to 12 persons and outside SOLAS regulations, and 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 ± 0,4kN)

The white strong rope 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 4 metres, activate a sharp knife which cuts the white strong rope and the life raft 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 unit is totally weatherproof, requiring virtually no maintenance.

For larger liferafts 6-150 the Hammar H20 standard SOLAS HRU model is recommended, with a higher breaking strength).
