This film features a range of products made by Thos Smiths of Rodley focussing on diesel cranes. The film gives details of the following: Smith 8 popular with contractors and many large firms have fleets. It has low first cost and medium output and is shown trenching and skimming. Super 10 has 2 speed gearbox, enclosed mechanism and oil pump system. It has a higher cost offset by low maintenance and is very mobile due to precision gears.

This film features a range of products made by Thos Smiths of Rodley focussing on diesel cranes. The film gives details of the following: Smith 8 popular with contractors and many large firms have fleets. It has low first cost and medium output and is shown trenching and skimming. Super 10 has 2 speed gearbox, enclosed mechanism and oil pump system. It has a higher cost offset by low maintenance and is very mobile due to precision gears. The crane is shown on trenching, dragline work and grab at NE Gas Board, and open cast coal mining at Leeds. MkI:21 is a development of 5-20 wartime machine and has 3/4 yard bucket capacity and high output. Power clutches prevent operator fatigue and allow longer working. Mk3:21 has 72hp 6 cylinder diesel engine and is only British machine with a 37ft dragline radius - ideal for latter and digging and high grab work. It has 2 power operated cable drums for twin lines. This company recently began producing goose necked trenchers - US development made by Smiths for overseas markets. This particular machine has a kinked boom which allows deep digging. Smiths export electric cranes, i.e. grabbing, gantry, level ploughing etc. The first overhead crane was supplied to John Fowlers in 1894, and in the 1950s building electric motor cranes through subsidiary John Smith (Keighley) Ltd., Gantry cranes supplied to ports and naval dockyards. Seen here is the five ton level ploughing at London Docks. Demand for diesel cranes increasing due to better running costs, design improvements, low maintenance and performance. There were also recently introduced fluid couplings and toggle clutches for hoists, which increased operator speed. Smiths also have service engineer backup. The film shows van taking parcel to BKS Air Services plane, most likely at Yeadon airport.
