2.3 Description of Product Functions
2.3.1 Mechanical parts
All the door drives operate according to the same function principle. The doors are activated by a d.c. mo-
tor using toothed belts and two or more pusher dogs.
The d.c. motor drives a toothed belt, which runs over double toothed belt pulleys. The pusher dogs are fas-
tened to the toothed belts by means of a catch. The cab doors are firmly interconnected with the pusher
dogs. The height of the toothed belts can be adjusted by adjusting the double toothed belt pulleys (eccen-
tric).
