5.2 Cleaning
The machine should be cleaned with a low-pressure water jet, a microfiber cloth and a mild
cleaning solution. Cleaning should only be carried out with the cradle lowered.
Do not clean the machine with a high-pressure water jet, such as a waterblaster.
For IP ratings of the machine and various subcomponents refer to Section 2.9 .
If it is required that the cradle be raised during cleaning, the control system may be
modified to permit this while maintaining operator safety
– contact your agent for details.
5.3 Cradle jams
Occasionally the bin cradle may become jammed at some point in the tipping cycle. This is
usually a minor issue which may be easily rectified.
The cradle is not powered down – it is lowered by gravity alone.
Refer to Section 5.7 for details and schematics of the hydraulic system.
5.3.1 Cradle jams while raising
If the cradle jams while raising the cause may be either an overweight bin, or a mechanical
fault, such as a bent tipping guide or misaligned roller.
5.3.1.1 Overweight bin
1. Lower the cradle to ground level, open the door and remove the bin.
2. Manually remove some material from the bin, then try again.
If the pressure-relief valve is adjusted incorrectly, the cradle may stall even when lifting
bins that are within the rated capacity of the machine. Adjustment of the pressure-relief
valve should only be carried out by a suitably qualified technician, with prior
authorization from Simpro.
5.3.1.2 Mechanical fault
1. If possible, lower the cradle to ground level, open the door and remove the bin.
2. Attempt to visually identify the cause of the jamming. The most likely causes are:
a. The lifting chain may have derailed from the plastic guide at the top of the
mast, on the side opposite the lift ram.
b. A mast may have been bent or damaged, jamming one of the mast rollers.
c. On machines with a single ‘tipping track’ in the middle, the top part o f the
track may have been bent, interfering with the correct geometry of the
‘follower roller’.
d. Lack of lubrication on the follower roller, or the main cradle axle.
e. The cradle may be sitting out of level, due to poor adjustment of the lifting
chains or to a breakage.
f. The ‘roller arm(s)’ may be pressing against the ‘tipping track’, due to the
cradle sitting out of level, or not being properly centred between the masts.
