1. The winch should be mounted with the centerline
of the drum in a horizontal position. The mounting
plane of the base may be rotated in any position
around this centerline.
2. Because of the design of the mounting base, the
direction of line pull should only be as shown in the
above illustration. Line pulls in any other direction
must be approved by BRADEN Engineering.
3. When mounting the winch, use all four (4) mount-
ing holes and grade 5 (8.8) or better bolts and nuts.
Tighten to recommended torque.
It is important that the winch is mounted on a surface
that will not flex when the winch is in use, and cause
binding of the gear train. Binding in the gear train will
result in accelerated wear and heat. Also, be sure
the winch is mounted on a flat surface. If necessary,
use shim stock to insure the mounting surface is flat
within 0.020 inch (0.5 mm).
4. The vent plug must always be located above the
horizontal centerline. If the winch is mounted on a
pivoting surface, be sure vent plug remains above
the centerline in all positions. If necessary, reposition
bearing support and vent plug as follows:
A. Remove bearing support bolts.
B. Rotate bearing support until vent plug is
positioned correctly and bolt holes are
aligned.
C. Evenly tighten bolts to recommended
torque.
5. Hydraulic lines and components that operate the
winch should be of sufficient size to assure minimum
back pressure at the winch. The motor manufacturer
recommends that the back pressure not to exceed
100 PSI (690 kPa) for optimum motor seal life. 150
PSI (1,030 kPa) is the maximum allowable back
pressure. The standard winch is supplied with the
motor internally drained. If high back pressures are
encountered, the motor may be externally drained
directly to tank to improve motor seal life. For back
pressures exceeding 150 PSI (1,030 kPa) consult
BRADEN Service Department.
6. The winch should be mounted perpendicular to an
imaginary line from the center of the drum to the first
sheave to insure even spooling. Make certain the
fleet angle does not exceed 1-1/2 degrees.
