Hoist Installation - BRADEN PD12C Series Installation Maintenance And Service Manual

HOIST INSTALLATION

1. The hoist 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 hoist, use all eight (8) mounting
holes and grade 8 capscrews and nuts. Tighten to
recommended torque.
It is important that the hoist is mounted on a surface
that will not fl ex when 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 hoist
is mounted on a fl at surface. If necessary, use shim
stock to insure the mounting surface is fl at within
0.020 in. (0.5 mm). Use stainless steel shim stock
as required.

4. The vent plug must always be located above the
horizontal centerline. If the hoist is mounted on a
pivoting surface, be sure vent plug remains above
the centerline in all positions. If necessary, reposi-
tion bearing support and vent plug as follows:
5. Hydraulic lines and components that operate the
hoist must be of suffi cient size to assure minimum
back-pressure at the hoist motor ports. The hydrau-
lic back-pressure measured at the motor work ports
must be less than 100 PSI (690 kPa) at full operating
fl ow. Back-pressure in excess of 100 PSI (690 kPa)
will shorten motor shaft seal life and partially release
the load holding brake. The standard hoist is sup-
plied with the gear motor internally drained and con-
nected the drain by-pass port on the Braden brake
valve. If high back-pressures are encountered, the
motor should be externally drained directly to the
reservoir and the "DRAIN" port on the brake valve
capped. All piston motors MUST be drained directly
to the reservoir. The piston motor case drain port
must NEVER be exposed to more than 42 PSI (290
kPa); shaft seal damage will occur.
6. The hoist should be mounted perpendicular to an
imaginary line from the center of the drum to the fi rst
sheave to insure even spooling. Make certain the
fl eet angle does not exceed 1-1/2 degrees.
