A K.L.M. Servicing Innovation: Some Details of a Test Trolley for the Wright R‐2800 Engines of the DC‐6 Available to Purchase

THE general purpose of the test trolley is to replace the operating and control mechanics in the cockpit so that each engine can be tested before being mounted in position on the aircraft. The advantage as compared with the method previously employed is that if any auxiliary components are not working properly (or are wrongly connected) they can be found and adjusted before the engine is installed; this greatly reduces the risk of having to waste time on dismantling the engine again and makes sure that a properly functioning engine unit is installed.
