INSTALLATION AND OPERATING
INSTRUCTIONS
PRE-INSTALLATION
On arrival of the equipment it is advisable to check that all packages listed on
the consignment note have been received.
The equipment must be offloaded using certified lifting gear of suitable
capacity, by a com petent person.
When unloading the mixer, care must be taken to ensure the discharge chute
remains clear of obstructions as the chute and door hang below the chassis.
An outline drawing and bolt hold plan is normally sent prior to the despatch of
the machine and will enable preparations to be ma de for the installation. With
the `picture` of what the machine will look like when it is assembled, the
ancillary equipment dismantled for transport can easily be identified.
INSTALLATION
Please refer to contract arrangement and site instructions as applicable.
It is recommended that a concrete foundation (to take foundation bolts – not
supplied) of at least 0.6m
2
by 0.3m thick to take M20 bolts should be provided
for each leg of the support structure and runway when fitted. When the machine
is supplied without a support structure it should be mounted on supports of
sufficient strength and rigidity to prevent undue vibration when the machine is
working. When making provision for a loading hopper pit it is strongly
recommended that the pit is concreted out so that it can easily be kept clean and
free from any build up which could prevent the bottom limit switch from
operating correctly.
Before completing the installation, check that the main mixer frame is level
with a spirit level. Packings should be inserted as required under the structure
legs or main frame. The packings under the mixing pan roller brackets are set
during manufacturing and must not be disturbed under any circumstances.
Check that the pan is seated and that the pan rack and drive gear are in mesh..
Also check that all the blade clearances are in line with the maintenance
instructions.
On connecting to the power supply, the wiring diagram must be referred to.
A check that the wiring is correct is the rotation of the following:-
• The mixing pan and mixing star rotate anti-clockwise when looking from
the top.
• The loader winch rotates anti-clockwise looking from the rope drum end
when the raise button is pressed.
• The whirler unit rotates clockwise when looking from the top.
It is advisable to mount the starters away from the machine on supports free
from vibration. Ensure that the starters are fitted with suitable overloads – see
technical specification – power units.
Note:- it is recommended that the
mains electrical supply is taken via an earth leakage circuit breaker.
A simple Water Flow Meter is available as an option to the water tank, this has
a range of 0-100 litres and features an adjustable flow indicator with a reset
facility allowing very accurate measurement of water flow irrespective of the
pressure. The Flow Meter is normally fitted with a manual ‘on/off’ valve and is
protected by a washable in line strainer.
A supply of compressed air at 5.5 bars is required. The inlet for the connection
from the air line is tapped ½” B.S.P. A drop in pressure will cause incorrect
operation of the pneumatic system.
OPERATING THE MACHINE
Before starting production the following points should checked:-
(1) That there is oil in (a) the Star Drive Gearbox
(b) the Pan Drive Gearbox
(c) the Loader Winch Gearbox (when fitted)
(d) the Air Line lubricator
(2) The Mixing pan should be clear of loose nuts, bolts, spanners etc., as
these will damage the fingers and blades.
(3) Check that the Discharge Door and Discharge Blade are operating
correctly.
(4) Check that the blade clearances are correct and if necessary adjust, in line
with the maintenance instructions.
(5) Check that the limit switches on the loader stop the Loading Hopper in
the required positions at the top and bottom of the runway.
(6) Check that the Water tank is set to the required amount and is filling up
to this level. (See later page for further information on Water Ta nk
operation).
(7) When Weigh Gear is fitted check that the setting arrangements and
lubrication requirements have been carried out.
(8) If a Flow Meter is fitted check that the pointer is reset to zero and the
strainer is clean and free from debris.
IMPORTANT:
The CUMFLOW is a high performance Mixer.
The following precautions are necessary to obtain the best results and to avoid
damage to the Mixing Star and Drive.
AGGREGATES:
Strict control of graded aggregates must be maintained. Maximum Size 38mm.
Oversize lumps of aggregate or rogue material must be prevented from entering
the Pan.
MIXING STAR BLADES:
They are of a special shape and material to prolong wear life. They should not
be modified in any way and only replaced by genuine ‘WINGET CROKER’
spares.
Daily check is advised to ensure that the Blades/Wearing Pieces are securely
bolted and undamaged.
PAN RIM & BASE WEARING PLATES:
They must be replaced before excessive wear causes distortion.
MAXIMUM BATCH LOADS:
Under no circumstances should the Maximum Batch Loads quoted be
exceeded nor should the Mixer be stopped and re-started when there is a mix in
the Pan.
After each mix the contents of the pan must be completely discharged
before attempting to close the discharge door. At the end of each period of
operation the mixing pan, mixing blades, discharge blade and fingers,
discharge chute, discharge door and seating must be washed down to
prevent concrete setting on them and so impairing the efficiency of the
machine.
WARNING:
THE MAUFACTURER ACCEPTS NO RESPONSIBILITY FOR ANY
DAMAGE OR FAILURE RESULTING FROM OPERATIONAL MISUSE OR MALPRACTICE.
OPERATING INSTRUCTIONS FOR WEIGH GEAR MECHANISM
HYDROSTATIC LOADCELL & GAUGE
The Hydrostatic Load Cell is connected by a flexible capillary tube (approx 9.7
metres long) to a 300mm (12”) diameter weigh gauge.
The whole system is assembled and filled with fluid under vacuum and under
no circumstances should any of the components be disconnected, in the event
of component damage the complete assembly should be returned to Winget
Limited for repair.
The system is factory calibrated and any variation between the calculated tare
and the actual tare recorded can be corrected by means of the tare adjustment
knob on the side of the gauge.
With no load acting on the loadcell the pointer will be below zero, this is to
accommodate the weight of the hopper. When the hopper is placed on to the
loadcell the pointer will register zero. Final zero adjustment can be made via
the zero adjustment knob on the side of the gauge housing.
ELECTRONIC LOADCELL & GAUGE
The electronic Loadcell & Gauge consists of an electrically operated loadcell
mounted on the weigher fram e and connected to a remote mounted digital
readout control box. The connecting lead should be protected from damage
and the readout box mounted such that it is not affected by vibrations etc. T he
mounting instructions detailed within Section 9 of this m anual should be
followed to avoid excess vibrations damaging the control box. Section 9 also
contains detailed advice on setting up, obtaining zero and operation of the
loadcell and readout box and should be referred to before the equipment is
operated.

OPERATING INSTRUCTIONS FOR 0-100 LITRE
The simple manually operated 0-100 litre Water Flow Meter is available as an
option to the water tank and is normally mounted on the side of the mixer
feeding directly into the pan. The me ter is normally fitted with 1” hose tail
connectors but different sizes of water inlet connections to suit various hose
diameters are also available. The meter is normally provided with a simple
‘on/off’ valve and inline filter/strainer mounted next to but down stream of the
flowmeter.
WATER FLOWMETER
OPERATION
On a daily basis before use the strainer should be removed and checked for
debris and obstructions, cleaned and refitted. Ensure the on/off valve is in the
‘off ‘ position and turn on the main water supply. Set the adjustable pointer on
the dial face via the central knob to the required amount of water. Check the
indicator reads zero, if not operate the reset lever on the side of the meter which
will reset the indicator. Turn the on/off valve slowly to the ‘on’ position
watching the movement of the indicator around the dial, when the indicator
reaches the pointer sharply turn valve to the ‘off ‘ position. The indicator will
register the amount of water delivered. Operate the reset lever to bring the
indicator back to zero and repeat the operation for each batch of material
mixed.
When shutting down the mixer either at night or at the end of each shift it is
recommended that the main water supply to the flow meter and ‘on/off’ valve is
shut off.
If it is expected that the overnight temperatures will drop to or close to freezing
it is recommended that the Flow Meter, Valve, Filter and Pipework are drained
to prevent damage.
