3.4 SHEAVE/GUIDE YOKE INSTALLATION
The sheave/guide yoke must be installed after the Jack Unit and Upstand Post are assembled
and while the scaffolding is still in the hoistway. This is a heavy piece. Make sure you have
sufficient help to assist in placing the yoke in position. Use a safety line.

NOTE
To facilitate the mounting of the yoke assembly onto the jack, it is easier to pre-assemble the
guide shoes on the yoke before climbing the scaffold.
To install the yoke assembly proceed as follows:
1) Install the two (2) guide shoes, one on each side of the yoke and insert the nuts but do not
tighten (Figure 29).
2) Loosen the eight (8) nuts and bolts on either end of the yoke to make it easier to “squeeze”
the yoke assembly between the rails.
3) While standing on the scaffold, install the Jack Platen Plate on top of the jack and tighten
(Figures 30 and 31). Note the difference when a Car Top Prop is used.
