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. In total, 31 tractors were manufactured by Clayton Engineering Limited of Knighton, Powys.

Mersey-class lifeboats are All-weather lifeboats operated by the Royal National Lifeboat Institution (RNLI) from stations around the coasts of Great Britain and Ireland, with three former RNLI boats operated by ADES Uruguay, and one by Bote Salvavidas de Valparaiso, Chile. They are capable of operating at up to 17 knots (31 km/h) and can be launched from a carriage or by slipway.
