Talus MB-H is a continuous track launch tractor which was specifically designed for the Royal National Lifeboat Institution (RNLI), to launch and recover lifeboats from beach-launched lifeboat stations. The tractor was built by Clayton Engineering Limited in Knighton, Powys. The tractor is now largely being discontinued because the RNLI have now replaced the Mersey class all-weather lifeboat with the new Shannon Class Lifeboat which uses the new Launch and Recovery System from Supacat.
