If a hoist exhibits any sign of erratic operation or load control difficulties (i.e., load creeping or chattering), appropriate
troubleshooting tests and repairs should be performed immediately. Continued operation in this manner may result in
property damage, serious personal injury, or death.
TROUBLESHOOTING
TROUBLE
PROBABLE CAUSE
REMEDY
A
The hoist will not lower the load or
does not lower the load smoothly.
1. The problem could be a plugged or
loose pilot orifice. The pilot orifice is
a small pipe plug with a hole drilled
through it, located behind the pilot port
fitting on the brake valve. If it becomes
plugged, it will prevent the pilot pres-
sure, from the manifold, from opening
the brake valve. If it becomes loose, it
will allow an unregulated amount of
oil in to operate the brake valve which
cause erratic brake valve operation.
2. The friction brake may not be releas-
ing as a result of a defective brake cyl-
inder seal.
NOTE:
If the brake cylinder seal is de-
fective you will usually find oil leaking
from the hoist vent plug.
1. Remove pilot hose and fitting from
brake valve, then use a 5/32-inch Al-
len wrench to remove pilot orifice. The
diameter of the orifice is approximately
.020 inch. Clean and install pilot orifice
tightly in the brake valve.
2. Check brake cylinder seal as follows:
a. Disconnect the swivel tee from the
brake-release port. Connect a hand
pump with accurate 0-2,000 PSI gauge
and shut-off valve to the –4 JIC fitting
in the brake-relea
se
port.
b. Apply 1,000 PSI (6,900 kPa) to the
brake. Close shut-off valve and let stand
for five minutes.
c. If there is any loss of pressure in five
minutes, the brake cylinder should be
disassembled for inspection of the seal-
ing surfaces and replacement of the
seals. Refer to “Motor Support — Brake
Cylinder Service.”
