• A semi-trailer landing gear which is claimed to be lighter than traditional equipment but to have much stronger support legs has been developed by Lamross Transport Engineering Ltd., of Renfrew, Scotland. The Lamross legs are said to be able to withstand a shock loading of up to 52,5001b.
Two basic types are available—a heavyduty pattern for use with trailers of up to 27 tons gross and the other up to 16 tons gross. Both have steel outer casings, ribbed and with lap-welded joints. The bottom brace bracket of the outer casing is a steel casting to British Standards Specification. The legs have an 18in. outrun, and the 8.5in. overlap within the casing provides stability and added strength.
The heavy-duty leg is available with a choice of two gearboxes. In standard form gear ratios of 8 to 1 and 37 to 1 are provided. Alternatively, by permutation, ratios from 2.8 tol to 66 to 1 can be provided.
The light-duty leg has similar characteristics with the exception that the gear ratios are restricted to single speed 8 to 1, or two-speed with the 37 to 1 gearing added.
