Hydraulic System

The power train consists of one main drive. One gearbox drives four identical pumps which draw hydraulic oil from an unpressurised hydraulic tank. Open circuit hydraulics provide maximum cooling and filtering efficiency.

Rated flow (total output) 4140 ltr/min 1,096 U.S. gpm
Relief valve setting 310 bar 4,495 psi
Swing flow rate 1590 ltr/min 420 U.S. gpm
High pressure in line filters
one per pump located at the valve blocks
200 microns
Full flow return line filters (5 double)
at head of hydraulic tank
10 microns
Case drain return line filters (one double element) 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 prioritizes 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.

Automatic Centralized Lubrication

Two hydraulically powered Lincoln single line automatic lubrication systems are provided as standard, complete with time and volume variable controls. The central lube grease system is supplied from a refillable 200 litre (53 gal.) barrel. A second, identical system supplies open gear lubricant to the swing ring teeth through a lube pinion. Replenishment of the containers is through the Wiggins connections on the service arm.
