Trolley Retrieval Tool
ADRLSTBL100 and ADRLEST
The trolley retrieval tool (also called the end
stop/strap tool) enables a technician to pull the
trolley back without removing the cowling when the
trolley does not return to the start end of the rail.
1. At both ends of the rail, remove the stop screw
and slide out the spring and old stop block.
2. At the end of the rail, insert the new service
block.
3. Remove the camera trolley.
4. Fold the end of the strapping tape ¾ inch back
on itself. Then use a soldering iron to make a
hole in the folded tape.
5. Attach the strapping tape to the new service
block using an M3 screw.
6. With the strap facing the start end of the rail,
slide the block by hand into the stop groove for
about 50cm (20in).
7. Slide the trolley into the rail as far as it will go.
The strap should also slide.
8. At the start end of the rail, insert the slit of the
second service block into the stop groove to
hold the tape above it.

9. Let the roll of strap uncoil to the floor, and very
carefully, power up the rail. As the trolley
homes, it will pull some of the strap into the rail.
10. After the trolley homes, use AD SensorRail
Control software to set the maximum speed to
1m/s (3.3ft/s) so the trolley slowly pulls the
block and strap to the end of the rail. When
done, return the speed to 3m/s (9.8ft/s).
11. Once the trolley reaches the end of the rail,
remove the service block holding the tape at the
start end of the rail, turn the block around and
reinsert it into the stop groove, followed by the
spring and stop screw. Once this assembly is
installed, tighten the stop screw.
12. If the trolley requires service and does not
return to the start end of the rail, remove the
stop screw and spring at the start end and pull
the strap to move the trolley to the start of the
rail. Then, follow the steps above to reinstall the
strap.
