Hydraulics
Power to move more dirt, rock, and debris with speed and precision
Hydraulic Horsepower
Hydraulic horsepower is the actual machine power available
to do work through implements and work tools. It’s much
more than just the engine power under the hood – it’s a core
strength that differentiates Cat machines from other brands.
Hydraulic Pumps
The 320ELRR uses a two-pump, high-pressure hydraulic
system to tackle the toughest work in short order. A highly
efcient and simple back-to-back main control valve improves
fuel consumption and allows for greater tool versatility.
Heavy Lift
The 320ELRR features a heavy lift function to give more lift
capacity over the front. With a touch of a button, pressure
increases and engine speed reduces to give better control in
lifting those extra-tough-to-move materials like concrete pipe
and road construction barriers.
Swing Priority Circuit
The swing priority circuit on the 320ELRR uses an electric
valve that’s operated by the machine’s Electronic Control
Module (ECM). Compared to using a hydraulic valve, an
electric valve allows for more nely tuned control, which
iscritical during material loading.
Electric Boom Regeneration Valve
This valve minimizes pump ow when the boom lowers
down, which helps improve fuel efciency. It is optimized
for any dial speed setting being used by the operator,
which results in enhanced boom lowering speed for greater
controllability.
