DUST AND DEBRIS COLLECTION SYSTEM
DUST AND DEBRIS COLLECTION SYSTEM
DESCRIPTION
The dust and debris collection system consists of:
Suction fan
Dust and debris suction fi lter
Hopper
Suction hose
Suction inlet
Skirt
Gasket between suction inlet and hopper
Hopper lid
Hopper suction hole
Open lid support rod
Lifted hopper locking pins
Lifted hopper locking pins housing
Lifted hopper locking pins holes
Air breather fi lter
Hopper lid suction sealing gasket
The suction fan (A), activated by an hydraulic motor, creates vacuum inside the hopper (C). The vacuum determines the suction
capacity of the suction inlet (E) through the suction hose (D).
The hopper (C) is made of steel.
It is fastened with two pins to a mechanic/hydraulic lifting system (O) (for hopper lifting) and to a dumping system (P) (for hopper
tilting). The lid (H), which can be opened with an hydraulic control system, allows for debris discharging.
Both the lid (H) and the suction hole (I) are equipped with gaskets, which allow the suction inlet (E) to reach the maximum suction
capacity.
Inside the hopper there are two stainless steel fi lters having the following functions:
The suction fi lter (B) retains dust and debris during fan suction phase, and makes them settle in the hopper;
The breather fi lter (N) retains dust and debris escaped from the suction fi lter, and does not allow them to be discharged
externally.
Both fi lters can be easily removed and cleaned.
To perform checks and maintenance procedure safely with the hopper lifted and the lid opened, perform the following procedures:
Turn the rod (J) to lock the lid (H) in open position.
Remove the pins (K) from the housings (L) and place them into the holes (M) to lock the hopper (C) in lifted and dumped
position.
The suction inlet is made of sheet steel.
It is equipped with three wheels, which allow it to follow the pattern of the surface to be cleaned.
On its front side there is a skirt (F) that must be lifted to collect bulky debris.
