TIP
Time of unloading load box depends on the setting of the roof shield and covers placed in
load box and on the rotation speed of container auger conveyors.
In the final phase of unfolding the vertical conveyor the hydraulic ram speed should be
significantly reduced. Failing to reduce speed during unfolding causes the impact and
shakes the trailer.
Unloading with the use of channel chute
Position trailer so that the channel chute is directly above reception hopper
grating.
Immobilise tractor and trailer with parking brake.
Changes of lever setting (1) figure (4.5) set in position (B) or (C).
Open chute slide using tractor manifold lever
Start tractor PTO with the lowest rotation speed possible (auger conveyor
begins to rotate).
Wait until grain ceases to fall out of chute.
Using tractor manifold lever start hydraulic clutch for a few seconds (drive to
container auger is started).
Disconnect clutch. Operation of auger conveyors in container must be short
enough so that grain from the collecting shaft does not reach the vertical
conveyor.
During unloading monitor working pressure of hydraulic clutch.
During unloading using the channel chute there is no need to unfold the vertical conveyor.
The load from the container shall pour directly to the reception hopper grating. In the event of
overload, sudden increase in pressure at clutch or drive fault, immediately disconnect
hydraulic clutch and then the tractor PTO drive.
