4 Description
4.1 General information
The Aebi Schmidt automatic vacuum sweeper,
Model AS 990 is a machine mounted on an HGV
chassis. The HGV can be fitted with a single-circuit
hydraulic system to control the front-mounted
machines. The pick-up unit consists of vacuum unit
with two suction nozzles steered by guide rollers.
The sweeper liquid is picked up pneumatically, i.e.
a vacuum is created within the hopper by a high-
powered blower. This produces airflow within the
pick-up unit, which sucks up the dirt/liquid from the
sweeping surface and deposits it in the hopper.
Outgoing air is either routed upwards and out of
the unit or is blown out through the blast nozzles.
The machine can be fitted with the following
additional (optional) equipment:
Liquid pick-up system
Blowing equipment (Blowing direction right or left)
Raise/lower blowing direction
Channel brushes (right/left disc brushes)
Spray beam above leaf filter
Exhaust diffuser
Path marking with foam peaks
High-pressure spray equipment
Water tank heater
Aircraft stand cleaning system
Side suction unit
Front spray beam
Set/adjust speed of cylindrical brushes

4.4 Lashing and mounting points
4.4.1 Lashing points
Loading personnel must adhere to the regulations on
loading and handling and be experienced in properly
securing loads. The load surface must be free of dirt
(non-slip). The machine is to be parked securely on
the load surface. The machine is to be fastened and
lashed down in such a way that it cannot move on
the loading surface during braking, acceleration, and
when driving through curves. Particular care should
be taken to ensure that the machine is well secured
in the direction of travel (for braking manoeuvres).
Make sure that lashing materials used to secure
the machine do not cause damage to it. The stability
should be re-tested after it has been secured.
A subsequent check of the load, and rectification
if necessary (for example retensioning the lashing
material) is to be made after approximately 10 km
of transit.
4.4.2 Lashing points on the AS 990
The lashing points on the vehicle are to be used
to lash the machine. These points are described in
the operating manual or can be requested from
the manufacturer.
