Installing the Top Trough
The Top Trough holds the Hydraulic Cylinder and the Lifting Cables. It also supports the Trip Stop
Tube underneath it.
CAUTION Watch out for the already-installed cabling. Make sure they do not get in the way as
you move the Top Trough into position.
Important: The Top Trough must be installed in a specific orientation: the end with the Hydraulic
Cylinder
must
go over the Powerside Post; the end with the sheave assemblies
must
go over the Offside Post.
To install the Top Trough:
1. Using a Lifting device, raise the Top Trough into position on top of the two posts.
Check the orientation of the Top Trough: the end with the Hydraulic Cylinder must go over the
Powerside Post; the end with the four-groove sheave assemblies must go over the Offside Post.
2. Align the holes on the top of the Powerside Post with the holes on the bottom of the Top Trough,
then connect the two using the supplied 10 mm hex bolts, nuts, and the two pipe straps.
The pipe straps will be used later to hold in place the Hydraulic Lines that run from the Power Unit
to the Hydraulic Cylinder.
3. Align the holes on the top of the Offside Post with the holes on the bottom of the Top Trough, then
connect the two using the supplied 10 mm hex bolts, washers, and nuts.
The Offside Post connection to the Top Trough uses washers,
not
pipe straps.
