SPECIFICATIONS

Diesel Drive

Tier 2 engine:

Model ………………………………… 2 x Komatsu SDA16V160E-2

Type ………………………… 4-cycle, water-cooled, direct injection

Aspiration …………………………… Turbocharged and aftercooled

Number of cylinders …………………………………………… 16

Rated power ……………………2 x 1500 kW 2010 HP @ 1800 rpm

(SAE J1995)

Governor ……………………………………… All-speed, electronic

The integrated engine oil and filter system combining the oil stabilising

systems, Reserve and Centinel, with Eliminator oil filter extends the oil

change interval up to 4.000 hours based on oil analysis. The high capacity

Mesabi engine radiators are cooled by a hydraulically driven fan for

superior cooling efficiency.

 

Swing System

Hydraulic motors and drives ……………………………………… 3

Swing brake, service …………………………………Hydraulic brake

Swing brake, parking………………………………Wet, multiple-disc

Swing ring teeth ………………………………………… External

Swing speed (maximum) ………………………………… 2,7 rpm

 

Hydraulic System

The power train consists of two main drives. Each of the two gearboxes

drives four identical main pumps which draw hydraulic oil from an

unpressurised hydraulic tank. Open circuit hydraulics provide maximum

cooling and filtering efficiency.

Rated flow (total output)……………………8.280 ltr/min / 2,190 gpm

Relief valve setting……………………………… 310 bar / 4,495 psi

Swing flow rate …………………………… 2.070 ltr/min / 547 gpm

High pressure in line filters………………………………200 microns

one per pump located at the valve blocks

Full flow return line filters (7 elements) ………………… 10 microns

at head of hydraulic tank

Case drain/by-pass return line filters …………………… 3 microns

The four-circuit system features a load-limiting governor with oil delivery

summation to the working circuits and incorporates pressure cut-off

control. Hydropilot prioritises hydraulic flow giving smooth hydraulic

response, simple hydraulic system layout, and a reduced number of

components. The hydraulic system includes large swing-out vertical airto-oil hydraulic coolers with temperature-regulated hydraulically driven

fans.

 

Electric Drive

Type ……………………………… 2 x Squirrel cage induction motor

Power Output……………………………………………2 x 1450 kW

Voltage …………………………………………… 6.000 – 7.200 V*

Amperage (approximate) …………………… 2 x 155 A - 2 x 128 A

Frequency option ……………………………… 50 Hz @ 1500 rpm

* Other voltages available on request

 

Automatic Centralised Lubrication

Three hydraulically powered Lincoln single line automatic lubrication

systems are provided as standard, complete with time and volume

variable controls. The two central lubrication circuits and open gear

grease circuit are supplied by identical pump assemblies from refillable

containers which have a capacity of 3 x 300 litres (3 x 80 gal).

Replenishment of the containers is through the Wiggins connections on

the service arm.
