Ningbo Chiyang HRU-1R Hydrostatic Release Unit is designed for liferafts. This release unit consists of a double looped white rope line, a release unit (Release depth 1,5-4,0m), and a Red Weak Link （breaking strength 2,2±0,4kN）. The white strong rope of HRU-1R is secured to the deck or liferaft cradle and attached to the liferaft lashing with a manual release hook. If the ship sinks, the water pressure will, within 4 metres, activate the sharp knife which 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.
