2012 Caterpillar 320EL LR

Features
Cat® C6.6 ACERT™ Engine

The Cat C6.6 ACERT engine delivers more horsepower using significantly less fuel than the previous series engine.

Biodiesel-Ready Fuel System

The C6.6 ACERT engine is equipped with an electroniccontrolled high-pressure fuel system that includes an electric priming pump and three-layer fuel hoses to allow the use of biodiesel (meeting ASTM 6751 or EN 14214) up to B20 (biodiesel 20% mixture).

Cooling System

The cooling system features an air-to-air aftercooler and A/C condenser that tilt up and swing out of the way for easy servicing; the viscous fan automatically adjusts to ambient temperatures to help reduce fuel consumption and noise.

Main Control and Auxiliary Valves

The 320E uses a high-pressure hydraulic system to tackle the toughest of work in short order. A highly efficient and simple back-to-back main control valve improves fuel consumption and allows for greater tool versatility.

Heavy Lift

The 320E features a heavy lift mode, which increases machine system pressure to improve lift over the front of the machine – a nice benefit in challenging situations. The system’s pressure increase combined with a reduction in engine speed and heavier counterweight option give operators better control when lifting robust objects like concrete pipe and road construction barriers.

Service Doors

Wide service doors and a one-piece hood provide easy access to the engine and cooling compartments. Both doors and hood feature enhanced hardware and a new screen design to help minimize debris entry.
