The Powerscreen Powertrack is a high capacity heavy duty mobile scalping and conveying
unit.
Built to withstand the rigours of handling materials like rock or demolition concrete, this
machine is equally at home when fine screening down to 1/4 product size.
The product design allows the machine to operate in very confined spaces and the high
mobility factor eliminates set up time.
This means: Drive onto a level site, switch on the machine and produce graded material in
under 2 minutes.
The Powerscreen Powertrack machine is a specially adapted Powergrid fitted with crawler
tracks which can be moved along on site by the operator via remote radio control signal from
a hand held remote radio control unit. Road transport is by low-loading trailer only. To meet
transport regulations on low-loading trailer the overall height of the machine has been
reduced to 3.4m (11 2) and overall width is 2.93m (9 7). Legal limit is 3.0m (9 10).
The Powertrack chassis frame is reinforced and tracks are bolted in place using special
mounting brackets. The upper part of the chassis / framework is standard. Specially designed
mudguards along the tracks and tapered guard doors either end give the Powertrack a
streamlined shape.
Scalping Unit:
The scalping unit is constructed from heavy duty plate and box sections having
two screening surfaces 10 x 7 long each.
Scalping action is provided by flywheels and an eccentric screenshaft in a
conventional 2 bearing screen arrangement.
A fixed loading plate is standard equipment. A range of mesh sizes from 4 to
1/4 are available and are end tension design to facilitate replacement. A bofor
steel grizzly bar reject grid is fitted to the top deck.
The screening angle may be adjusted from 12 to 27 degrees by means of two
hydraulic rams.
Wear plates for screenbox wing plates sides and loading plate are optionally
available.

Powerunit:
Power is provided by a 97 Hp turbo diesel hydraulic unit. The Powerunit
including engine, hydraulic tank, pump, control valves, starter panel; battery is
enclosed in a cabinet mounted directly on top of the front chassis assembly. This
allows much easier access for operation and maintenance purposes.
Hopper and Conveyor:

A steel plate hopper mounted under the screen directs the material onto the
conveyor and rubber skirting eliminates spillage. The conveyor is 1500mm (5)
wide and discharges at a height of 2.55m (8 - 4). The belt is a 3 ply heavy duty
with vulcanised joint and fitted with self adjusting belt cleaner. The conveyor is
fully skirted to prevent material spillage.
Mobility & Transport:

The Powertrack is fitted with heavy duty excavator type crawler tracks to
facilitate mobility. For road transport the Powertrack is carried on a flat bed low
loader
Operation:
Output of 600 tonnes + per hour are achievable with a competent shovel operator
loading material evenly onto the screen.
There are many different applications and the variables within these can affect
tonnages achieved
Remote Control:
The radio control system consists of a receiver, a hand held battery powered radio
control unit and a remote hand help control unit with cable. The remote backup /
control unit by-passes the radio system completely and is a purely 12 volt electric
system. It would only be used in an emergency for example if remote control unit
was lost or damaged. The hand held remote control unit has two toggle switches
to operate each track forward and back independently, a button to operate the 12
volt diverter valve and an emergency stop button which stops the engine in an
emergency situation.
Page 5
Remote Control Cont'd:

The control unit has two rocker switches work as follows:(i)
Push both buttons forward - Powergrid moves forward in a straight line.
(ii)
Push both buttons backwards - Powergrid moves backwards in a straight
line.
(iii)
Push one button forward and one button back - Powergrid turns right
or left.
The radio control system also controls the operation of the conveyor and the
screenbox. These can be started and stopped using the hand held unit. When using the
hand remote unit to operate the machine, if the signal is broken due to interference the
machine will shut down. This is a safety feature and meets CE regulations.
OPTIONS
Top deck Screens:
The Powergrid screenbox has a number of different screen types apart from
conventional wire meshes. A Heavy Duty Bofor grid is available featuring a
tapered opening from 90mm to 110mm (3.5 to 4.3) nominal aperture. Punched
plate screens are available with a range of opening sizes up to 150mm
(hexagonal). A heavy duty solid steel plate finger screen is available with a range
of apertures.
Bottom deck Screens:

The Powergrid also has the option of finger screens on the bottom deck instead of
conventional wire meshes.
Hydraulics:
Variable speed control of main belt is available.
Remote Control Tipping:

The screenbox can be tipped from its screening position to its maximum screen
angle via the track unit radio control.

The screen and conveyor control valves operate the screen and conveyor as normal but two 12
volt diverter valves are fitted (one on each control valve outlet port). When the diverter valves
are activated (by one button on hand-held radio control unit) the screen and conveyor belt
stop and hydraulic oil is diverted through two 12 volt double acting solenoid valves, one used
to control each track. In other words, screen circuit drives the LH track and conveyor circuit
drives RH track.
The solenoid valves are operated by radio signal from a hand held remote control unit.
