Constant tension system
The winch is fitted with a constant tension system acting as wave compensator, allowing the rescue boat to follow the wave movements and holding the boat steady along the ship’s side once connected to the davit wire, ready for hoisting onboard. This system avoids critical dynamic forces to the rescue boat and crew in splash zone.
Recover with constant tension
Pictures illustrates a recovery operation using the constant tension winch system. The wire is lowered to the boat with slack wire; the boatman attaches it to the boat. The davit operator activates the constant tension on the winch to pick up the slack. As the boat rises and falls on the waves, the davit winch drum will automatically pay in and out in unison with the wave and ship motion, maintaining tension on the wire until the davit operator is ready to hoist the boat. As the boat approaches the crest of a wave, the operator de-activates the constant tension and lifts the boat clear of the waves.
Shock absorbing cylinder
Hydraulic cylinder mounted in davit jib acting as shock absorber for smooth handling of the boat. The shock absorber reduces dynamic forces acting on the boat and crew to a minimum during launching and retrieving of the boat. The shock absorber reduces dynamic forces acting on the boat and crew to a minimum during launching and retrieving of the boat.
Mechanical cradle supporting the rescue boat in parked position by two supporting arms pushing the boat from outside into the davit to secure safe parking. This system allows davit wire to be disconnected from release hook for maintenance and inspection while boat is in parked position.
Anti-pendulum arms secure safe handling of the boat when swinging in/out over the ship’s side. The arms prevent larger movements/pendulum in the critical phase during boat handling from parked position to launching position and vice versa.
Equipment mounted on davit allowing the davit to be operated in extreme low temperatures and in areas where icing occurs on equipment mounted on open deck. Depending of de-ice requirement, davit can be equipped with:
● Protection for operator handles
● Steel grade for low temperature
● Heater in oil tank
Docking head mounted in davit jib end acting as compensator for movements supporting the boat when swinging in/out over the ships side. The docking head secure safe handling of the boat by preventing larger movements in critical phase during launching and retrieval.
Painter line boom (towing boom)
Boom for operating painter line to secure boat in a safe position before launching and retrieval. Painter line boom can be fitted with winch and be of horizontal, vertical, or telescopic type.
Shot blasted to SA 2.5 and zinc metallized for increased protection.
Hatch opening system
Yard can deliver an opening hatch in front of the davit recess to completely give you an indoor environment with the best protection for davit and boat in harsh weather conditions. Red Rock can deliver the the opening arrangement for this, which needs to be SOLAS approved for Rescue Boats.
