ANCHOR WOOD PAD / WINCH TO WALL
3.
Before installing wood pad/winch assembly to
wall, verify exact location of winch with
owner or architect. In determining the exact
winch location, the following must be
considered:

The operator must have a clear view of
the equipment he/she is operating.

Anticipate path of cable between winch
and pulley(s). Structural members, lights,
ducts, drain pipes, etc. are potential
obstacles.

The path of the cable cannot cause it to
contact any part of the backstop mast
during the folding cycles.

Extensive cable travel will require
additional idler pulleys to support the
cable run.
Refer to separate installation manual supplied
with backstops, etc. for supplemental
information on winch location, cable routing,
etc.
4. Anchor wood pad/winch assembly (from Step
No. 2) to wall, using one of three suggested
anchor detail methods shown in Detail "C".
See Detail "B" for anchor spacing on wood
pad. Consult with architect or engineer to
verify wall capacity and to select appropriate
connections.
5. As an alternate, the winch can be mounted to
the face of a steel column (not shown).
