Lubrication:
apply grease to chain and cables, particularly where they contact
the wheels. Apply grease and oil/ WD 40 lubricant to the inside of the column
where the carriage will ride.
21.
Check all oil fittings
for a tight seal. There should be no oil leakage from
joints.
22.
Fill the oil container
with 10L of ISO grade 46 oil. Shell Telus 46 or an
equivalent 46 grade oil should be used.
The lift is now installed and ready for commissioning.
Hoist operation
The hoist is now fully installed and ready for its first test operation. This is where we
fine tune the installation and fix any problems.
These tests should be repeated monthly.
1.
Pump - Motor operation
:
a. Check all fittings to pump assembly are tight (they are typically loose as
fittings may need to be swapped from side to side for some hoists and
other hoists have different fittings to standard.)
b. The
qualified electrician will check that the wiring
to the pump is
correct
c. There are two connectors from the motor assembly one for power (3
wires), the other is a limit switch connector (white connector), on hoists
that do not have a limit switch this connector should be bridged (wires
connected) . If this connector is not bridged the motor will not start.
d. Check the oil container is full of oil – oil grad ISO grade 46
e. Push the green button on motor
f. The hydraulic oil should pressurize in the rams and lift the hoist
carriages.
g. Raise the hoist 300 mm and lower with the release lever just below the
pump motor
If you raise the hoist above the safety you will hear a clicking sound of
the safeties engaging in which case you will need to release the safety
latches as described below before lowering.
Test
•
Check each oil line connection for leaks and tighten gently and retest.
•
If arms do not lower automatically you may have:
o
Some binding in the column, place some weight on the columns
and try lowering
o
The oil release valve on the pump needs adjusting;; a small allen
key with the lock nut in the center of the pump assembly is used
to adjust this. This is a rare problem and should not be adjusted
immediately.
2. Safety release operation Safety latches engagement -1
a. Raise the hoist until you hear the safety latches engaging, a definite
clicking sound will be audible.
