Application
(refer to drawing)

1. After hoist ropes have been installed, take fully assembled RTG and loop rope hook  1  around one of the hoist ropes. Position RTG approximately 3 feet or more above counterweight shackles.
2. Place pivot arm
 2  against the rope. Tighten pivot arm clamp lever  3 .
3. Adjust position of the scale
 4  with stretch and attach scale hook to hoist rope. Tighten scale clamp lever  5 .
4. Take readings. Preferred range for proper tensioning is between 26 and 30 lbs. Tighten ropes to achieve this reading.
5. Repeat procedures 1-4 two more times, once below deflector sheave and once above car top fittings.

NOTE:
A and B dimensions will vary depend of cable diameter and load on cables.
At no time should the variance between ropes exceed 4 lbs.
