First carry out the
weekly and 6-weekly maintenance
• Attachment points
Tighten all the bin lift's attachment points, such as:
-
Mounting bolts of the bin lift system to the
refuse collection vehicle or adaptation frame
(assembly frame).
The tightening torque is 200 Nm.
-
Bin lift footboards (if applicable).
-
Check all bolt and nut connections.
• Check the pick-up teeth for wear.
• Bearing play
Check the bin lift for excessive bearing play.
-
Press the two lifting chairs axially towards each
other and measure the opening (see fig. 4.4a).
Then pull the lifting chairs axially apart and
measure the opening again.
The difference between these two measurements
may be no more than
10 mm
.
-
Grip the lifting chair with two hands and try to
turn it vertically to the left (see fig. 4.4b) and
determine distance
X1
. Then rotate the chair
to the right and determine distance
X2
.
The sum of these two measurements may be no
more than
5 mm
.
Do the same with the other lifting chair.
• Pick-up comb tipping angle
The tipping angle has been set ex-factory. If the
pick-up combs do not make the same angle
when in the highest position, this can be
corrected by means of nuts
A
(see fig. 4.4c).
-
The nominal distance between the axles,
centre to centre, must be 730 mm.
• Cycle time
Check the bin lift cycle time.
The cycle time is calculated without the tipping
position time (dwell time) and depends on the body
height, bin/container weight and oil temperature.
-
For the measurements, use a 240 litre or a
1100 litre container. Start the measurement
when the wheels leave the ground and stop
the measurement when the wheels touch the
ground again. The tipping position time must
be subtracted from the measurement.
-
The cycle time may be no shorter than:
5 seconds for 2-wheel bins,
10 seconds for 4-wheel containers.
