A85 DO-DO Carriage
This "Drive On - Drive Off" - (DO-DO) Lifeboat launch and recovery carriage was designed and production engineered in conjunction with the RNLI to support the introduction of the A85 inshore lifeboat. This boat is 8.3m in length and has a maximum ballasted weight of 2.4 tonnes. Special versions are fitted with a hydraulic power pack to enable the boat to be angled for optimum launch and recovery parallel with the water from inclined beaches and slipways.
The carriage is a development of the original “DO-DO” trolley that has been in service for many years, catering for the A21 and A75 inshore lifeboats. The development programme for the new A85 carriage incorporated changes identified from manufacture, operation and re-furbishment of the original trolley.
The A85 carriage design incorporates a family of three variants: a standard carriage, an angled carriage that can elevate the main bed through 10 degrees, and an angled carriage bed mounted on a railway carriage system.
