11.8 Assemble the equalizing cables.
1. Remove sheave cover, Fig. 32.
2 Refer to Fig. 34 for the general cable
arrangement. First, run a cable end up through
the small hole in the lower tie-off plate, Fig. 35.
3 Push the cable up until the stud is out of the
carriage top opening.
4 Run a nylon insert lock nut onto the cable stud so
13mm of the stud extends out of the lock nut.
5 Pull the cable back down, Fig. 35.
6 Run cable around the lower sheave, then up and
around overhead sheave and across and down
to the opposite carriage, Fig. 34. Install sheave
cover, Fig. 32.
7 Fasten the cable end to the carriage upper tie-off
bracket. Tighten the lock nut enough to apply light
tension to the cable.
8 Repeat procedure for the second cable. Adjust
the tension of both cables during the nal
adjustments in Chapter 12 commissioning.

thickness steel pipe located at the
lower cable tie off. The lengths
required are as follows:
4" (102mm) Lower Height =
