Pick-up Hood
The pick-up hood is towed by 4 chains positioned at the front and rear. This allows the machine to
sweep forwards and backwards, as the pick-up hood will be guided during the travel mode. The
pick-up hood is lifted by two hydraulic cylinders, one either side that connect directly to the head.
The positive hydraulic check valve system will support the nozzle in the stowed position during
transit. Additional chains are located at the lift point and anchored to the chains support to prevent
excess sideways movement during sweeping.
Pick-up Hood Skate System
The pick-up hood runs on adjustable side skates that are carbide faced to improve wear. The water
system provides for front under skate lubrication on dry days for the carbide faces. These skates
are non handed and are mounted to the hood side plates by three locking nuts and one bolt that
locates into the rear side assembly skate.
The initial setting of the skate is on
the centre line of the skate side slots
and the skate can be lowered as it
wears by moving the skate down into
the slots. Re-tighten firmly the three
locating nuts and the locating bolt. The
skate adjustment is mainly for wear, but
you can set the front of the pick-up hood
higher to allow for a larger opening when
sweeping bulky items such as leaves.
The rear of the side skate should retain
the rear setting of the internal rubber so
as to maintain a close contact to the road
surface.
Pick-up Hood Suspension
The pick-up hood is suspended on eight
springs, four each side, two at the front
and two at the rear. These are set to
reduce the weight of the pick-up hood
on the ground and will reduce marking
of the ground surface. The initial setting
ex-factory should suit most conditions
and provides for a light (downward) force
to seal the hood via its internal flaps whilst
working under the suction pressure.
