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.

The Mersey-class has been replaced mostly with the new Shannon-class All-weather lifeboat, which uses the new Shannon Launch and Recovery System (SLARS) from Supacat and Clayton Engineering, or in some locations, with a B-class (Atlantic 85) Inshore lifeboat. As of September 2025, only two Mersey-class All-weather lifeboats remain in service with the RNLI, and only one is carriage launched, with the aid of the Talus MB-H. Newcastle Lifeboat Station will receive a B-class (Atlantic 85) and Talus MB-4H in late 2025.

Some of the surplus Talus MB-H tractors will be transferred for use at stations using the Inshore Atlantic 85, with a few retained in the relief fleet, whilst the rest are likely to be sold out of service. The following list will include those tractors now in use with Independent rescue services where known.
