1.2 Moving Mechanism
Improper handling.
Risk of injury!
Do not reach into the Perspex tank while the
moving mechanism is working.
Pay attention that hairs or cloths of the user and
other persons involved do not touch the rotating
spindle.
The moving mechanism is made of stainless steel
and is permanently installed on the tank. It consists
of three arms with the following designations:
A = horizontal arm, fixed,
B = moving vertical arm and
C = moving horizontal arm with slider.
The moving mechanism is suitable for both horizon-
tal and vertical radiation. Holding devices for detec-
tors to move in the field are screwed to the slider of
the C-arm. The slider and the arms are moved by
stepper motors that permit a minimum step width of
0.1 mm. The reproducibility of the geometric posi-
tioning is also ± 0.1 mm.
The moving range limits can be adjusted for each
axis and stored in the control unit to ensure that the
detector does not hit the Perspex walls.
The components of the moving mechanism, particu-
larly the guides and moving parts, are not adversely
affected by water. Bending or contortion due to
water absorption or corrosion are thus excluded.
