Evaluation of the driver's cab in the Rc5 engine

The opinion of engine drivers concerning the design of the cab in a new engine (Rc5, ASEA, Sweden) is surveyed in the present study, which is aimed at recommendations for further improvements of the new cab. Fifty engine drivers from the northern part of Sweden (Ange, Vannas and Boden), who had been driving the new engine, were selected at random to answer a specially designed questionnaire. Most of the drivers considered the new cab as better than the old one (Rc4) in several respects. Particularly appreciated was an adjustable footrest, on which the safety regulator pedal was fitted, which enabled an individually adjusted position for driving. They also preferred the automatic brake valve located close to the driver and with its movements in a sagittal direction. A number of proposals for further improvement of the cab are presented in order to attain an optimally designed driver's cab.
