All ROSTA Motorbases MB 70 will be supplied with
motor plate installed in
“centered”
configuration on
top of the element axis. According to the final positioning
of the base, the operating angle of the belts and the re-
quired tensioning travel, the motor plate can be altered in
“off-set”
position. Relevant threaded fixation holes are
existent in plate.
For possibly required additional tensioning travel of the
motor plate, the fork head of the pretensioning device
can be set in one of the eleven hole positions of the fric-
tion plate (3).
