OSI’s SECURE SALES ORDER CART - PRODUCT PAGE   Hydraulic Pivoting Davit: PFH 100 CT (Hydraulic Pivoting) 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 PFH 100 CT davit is a freestanding deck mounted davit consisting of two davit arms each supported by a base frame, hydraulic power pack unit and two hydraulically operated winches (one per davit arm). The system has been designed especially for safe and efficient launching/recovery of a fully manned workboat even under severe and adverse weather conditions (wind force 6 on the Beaufort-scale, Sea state 5). The PFH 100 CT series are all provided with a constant wire tensioning system and hydro-pneumatic shock absorbers. All system functions are hydraulically controlled and actuated from the davit’s operating console which is placed on deck near the railing. Lowering and recovery of the workboat is realised by means of two independent hydraulic driven winches. These winches are actuated by means of a hand control valve (joy stick). In case this valve is not operated, it will automatically return into ‘0’ position and the multi-disc brakes of the winches become activated and the hoisting or lowering motion stops immediately (dead man’s brake). In case of a power failure or malfunctioning of the electric system, hoisting can also be done manually by means of ratchet handles.
