Pneumatic unloading: Total flexibility
The pneumatic ship unloader only requires a pipeline
connection to handle the entire conveying process from
ship to store. This enables it to work in practically any
type of dock environment. The pipeline may run below,
at or above ground level. The unloader also functions
with removable pipeline sections.
The large pneumatic unloader can reach the entire ship’s
hold without repositioning. This unique feature allows
dock-mobile, barge-mounted and rail-mounted configurations, all offering a very high average through-the-ship
capacity. The easily manoeuvrable vacuum suction arm
combines high efficiency with superior environmental
characteristics.
Vacuum unloading provides
excellent cleaning capability.

Sized to fit
180 TPH
Pneumatic unloaders are available in
various capacity ranges depending on
the size of the terminal in question. The
180 tph Kovako Road-Mobile Unloader
is an excellent solution for small vessels.
300 TPH
For medium sized terminals the 300 tph
pneumatic unloader offers a competitive
solution for rail-mounted, dock-mobile
or barge-mounted configurations.
425 TPH
Terminals with a high throughput require
a high capacity shipunloader. The 425
tph pneumatic unloader caters for this
need and various configurations are
available.
600 TPH
The top of the line pneumatic unloader
has a throughput of 600 tph. To make
optimum use of this large unloader,
the railmounted version is the preferred
solution.

The unloading process
The highly manoeuvrable vacuum arm can access
any part of the hold without repositioning the
unloader. The cargo can be unloaded in a level way
without creating dust emission.
1
Using a remote control unit, the operator directs
the movements of the suction arm.
2
The material is mixed with air at the suction
nozzle and vacuumed into the suction pipeline.
3
The 360 degrees rotation of the 3rd arm section
enables it to reach into all corners of the hold.
4
The mixture of material and air is vacuumed
through the suction air pipeline to the filter tank.
5
Air and material are separated inside the filter
tank. The material then drops down into one of
the two transfer tanks.
6
The transfer tanks alternate between being filled
with material and being blown empty.
7
The air used for the vacuum conveying process is
cleaned by high efficiency filters in the filter tank.
8
The vacuum pumps that provide the air for the
vacuum conveying process are located in a
machine room on the unloader.
9
The compressors for the conveying process are
located in a machine room on the unloader or
on the quay as shown.
10
The compressed air passes via a pipeline and a
rubber hose connection to the ship unloader.
11
The compressed air is mixed with the material in
the transfer tank.
12
The material is conveyed to the storage through
the rubber hose connection and the pipeline on
shore.
13
The whole unloading process is fully automatic
and interfaced with the control system of the
storage facility.

Made to match
Rail-mounted unloaders
Large pneumatic unloaders come in various configurations
to match specific unloading situations. A rail-mounted
unloader moves easily and quickly alongside the ship,
allowing a high through-the-ship unloading rate.
Dock-mobile unloaders
In cases where there are no rails available or the
unloader cannot be located permanently on the
quay, a dock-mobile unloader is an excellent
solution. Dock-mobile unloaders are either selfpropelled or pulled by a front-end loader.
Barge-mounted unloaders
In cases where no suitable dock facilities are
available or the unloader is to be used at several
terminals, a barge-mounted pneumatic unloader
is the ideal solution. Complete accessibility of the
entire hold without repositioning the barge and
an easy rubber hose onshore connection are
significant advantages offered by this type of
unloader.
