The NED-DECK MARINE hydraulic pivoting davits have been designed for long time operation under adverse and extreme conditions in a highly corrosive marine environment. The hydraulic pivoting davits of the PRH series are so-called “plug-in and play units” all guaranteeing easy installation on board. The PRH davit is a freestanding deck mounted davit consisting of a base frame, davit arm, cylinders, winch and hydraulic power pack unit. The system has been designed to meet the latest IMO requirements and is suitable for safe and efficient launching and recovery of a fully manned fast rescue boat even under severe and adverse weather conditions (wind force 6 on the Beaufort-scale, in association with a significant wave height of at least 3 m). The PRH series are all provided with a constant wire tensioning system and hydro-pneumatic shock absorber.
