1.5 Hopper
The hopper is made out of stainless steel (optional Aluminium) and is mounted onto the
base framework using robust bearing blocks.
The hopper capacity is approx. 2,2 m
3
.
Observation flaps has been set into each side of the hopper, so that the fill volume can
be controlled and to allow that bulky objects, which cannot be picked up by the suction
hood, can be manually thrown into the hopper.
A wear-resistant elastic spiral hose, 220 mm in diameter, connects the suction hood to
the hopper.
A rubber-lined baffle plate is installed above the suction air inlet of the hopper. The
sucked air then flows via the filter plates fitted on the upper right and left-hand sides of
the hopper through the air duct into the suction fan and then is dispersed over the
exhaust-air duct.
The contents of the hopper are emptied through a large flap that covers the entire rear
side of the hopper. The flap is closed by hand, the flap is opened kept in the opened
position using gas filled spring cylinders.
The locking mechanism for the closed flap is operated using an electric motor.
The hopper is tipped by using 2 hydraulic cylinders; through the high position of the
bearing blocks a tipping height of approx. 1,450 mm is obtained. The tipped hopper can
be secured using the supplied safety support bar.

1.7 Suction Fan Unit
The suction fan unit is mounted, elastically supported, at the front end of the base
framework.
The suction fan unit is fitted with high-performance suction fan blade which has been
designed to obtain an optional suction efficiency for the sweepings.
The suction fan is driven by a hydraulic axial piston motor which is flange-mounted onto
the suction fan unit. The hydraulic motor is driven by the hydraulic oil supplied by the
hydraulic system of the Multicar chassis.
The exhaust air of the suction fan is so dispersed underneath the sweeper body, that
there is no annoyance from the air flow, even in the immediate vicinity of the sweeper.
1.8 Sweeping and Suction Unit
The sweeping and suction gear is mounted onto a swivelling frame on the rear side of
the base framework and consists of:
•Swivelling arm (allows sweeping and suction unit to be swivelled to the side of the
vehicle when the hopper is emptied)
•Lifting arm (lifts and lowers the sweeping and suction unit)
•Floating arm (automatically adjusts so the sweeping and suction units are parallel to
the road surface even when the road slopes)
•Suction hood with suction hose
•Bulky debris pick-up flap
•2 disk brush units
The suction hood with suction hose is mounted in the middle of the floating arm.
The bulky debris pick-up flap is located in front of the suction hood.
The disk brush units are mounted onto the right and left sides of the floating arm and
their height can be adjusted by hand; the brushes can also be swivelled outwards.
While sweeping, the floating arm is trailed behind the vehicle on two robust large
support wheels (∅250mm). The sweeping and suction unit on the floating arm are
raised from the road surface by a hydraulic cylinder on the lifting arm.
When the hopper is to be emptied, the complete sweeping and suction unit is swivelled
to the side of the vehicle using the swivelling arm.
To reduce the quantity of dust raised while sweeping, all sweeping and suction units are
fitted with a spray water nozzles.

* Optional equipment Page 10
1.12 Spray Water System
The spray water system is fitted to reduce the quantity of dust raised during the
sweeping operation and helps to separate the dust from the sucked debris in the
hopper.
The standard delivered hand spray pistol and hose are used to clean the discharge flap
sealing and the interior of the hopper after dumping.
The water is separately supplied via solenoid valves, to the suction hood, disk brushes
and front brush*.
The spray water system consists of:
•Water tank, 370 l (250 l with low-height models)
•Water filling equipment
•Water drainage equipment
•Water filter
•Water pump, electrically powered
•Overpressure valve
•Solenoid valves, to actuate the spray nozzles
•Spray nozzles:
Disk brushes 2 nozzles each brush
Suction hood 5 nozzles
Front brush* 4 nozzles
•Water filling hose with C-coupling and hydrant key
•Water hose with spray pistol
The water tank is filled using a pressureless none return flow system, which conforms
to the requirements of the “protection of drinking water from contamination in water
supply systems“.
The water level in the water tank can be controlled using the water level gauge.
The electrical water pump (dry running safe) is designed so that it will not be damaged
when running without water. The pump delivers a volume of approx. 15 l/min. While
sweeping, the water pressure of the spray water system is adjusted to max. 2 bar. The
water hose and spray pistol can be connected to the sweeper unit using the quick
release coupling for the water to the suction hood.

Gebrüder TRILETY Ges.m.b.H. MCK-M31 1.02 09/ 2018
* Optional equipment Page 11
1.13 Operation Principle
As the vehicle drives, the disk brushes sweep the debris in front of the suction hood.
The swept width can be increased by actuating the front brush* (optional equipment).
The front brush also facilitates the sweeping of road bays and between parked cars.
To reduce the quantity of dust raised while sweeping, the debris is sprayed with water
by means of spray nozzles fitted onto the sweeping and suction units.
The suction fan generates a vacuum in the hopper, this vacuum then sucks the
sweeping through the suction hood and the flexible suction hose into the hopper.
Due to the much larger cross-section in the hopper, the speed of the sucked air is
considerably reduced and the debris then settles in the hopper. A rubber-lined baffle
plate, fitted above the suction connection piece in the hopper, protects the hopper roof
from damage.
The suction fan then sucks the air, free from the sweeping through the filter screens
and then blows it into the exhaust air duct. The filter screens prevent that bulky but light
debris (paper, leaves etc.) are not sucked into the suction fan.
