Water weights are water filled bags which are designed as a safe, practical and economical method of non-destructive testing and checking the structural integrity of cranes, davits, lifeboats, link spans, ramps and lifts, floors and bridges.
The Shannon launch and recovery system (SLARS) was developed to launch and recover the 18-tonne Shannon-class RNLI lifeboat. [3] [4] SLARS SC-T08 with the St Ives lifeboat Nora Stachura. The lifeboat is launched, and recovered, bow-first. The carriage, mounted on tracked wheels, is used to transport a lifeboat from boathouse to sea.
Off-load This release mechanism requires the weight (load) of the lifeboat to not be on the hook when it is released. This includes the Titanic-era Monomony hook design that requires someone to remove the hook from the lifeboat by hand. But this type also includes the hydrostatic system many lifeboats use now.
The mechanical advantage is 2, requiring a force of only 50 N to lift the load. A block and tackle is characterized by the use of a single continuous rope to transmit a tension force around one or more pulleys to lift or move a load. Its mechanical advantage is the number of parts of the rope that act on the load. The mechanical advantage of a ...
The RNLI engineering department in Poole worked with the tractor company New Holland to design a small launch tractor for stations which operate D-class inflatable lifeboats. The powerful small diesel engine gives out 45 hp (34 kW). [1] The tractor is undersealed to resist a saline environment. The tractor is fitted with turf tyres, which ...
RNLI inshore rescue boat during Falmouth Lifeboat Day, August 2006. A rigid inflatable boat (RIB), also rigid-hull inflatable boat or rigid-hulled inflatable boat (RHIB), is a lightweight but high-performance and high-capacity boat constructed with a rigid hull bottom joined to side-forming air tubes that are inflated with air to a high pressure so as to give the sides resilient rigidity along ...
TEMPSC Lifeboat in Bristol harbour, England TEMPSC is an acronym for "Totally Enclosed Motor Propelled Survival Craft", which was originally designed for offshore oil and gas platforms in 1968. The first-ever TEMPSC was spherical in shape, had a flat bottom, a single hook, with a total passenger capacity of 28 passengers and a fire-retardant ...
Talus MB-H is a continuous track launch tractor which was specifically designed for the Royal National Lifeboat Institution (RNLI), to launch and recover carriage mounted lifeboats, particularly the Mersey-class lifeboat, from beach-launched lifeboat stations. [1] In total, 31 tractors were manufactured by Clayton Engineering Limited of ...
