The Cat 336F L XE hybrid excavator features an integrated design that conserves fuel, optimises performance, and captures and reuses energy.

The machine delivers an estimated fuel savings of up to 20% compared with its standard 336 counterpart with no compromise in performance and no added maintenance costs. The new Cat Production Measurement system adds even more value by enabling operators to load trucks with just the right weight while allowing managers to remotely monitor the machine’s productivity.

The 308 HP (230 kW) C9.3 engine meets U.S. EPA Tier 4 Final emissions regulations without interrupting the operator or the job.

Proven electronic, fuel, air, and after treatment components ensure customer expectations for productivity, fuel efficiency, reliability, and service life are met.

Fuel efficiency of the C9.3 is further enhanced with automatic engine speed control, a programmable engine idle shutdown feature, and an ECO mode that allows operators to tailor machine performance to the application.

The engine also runs efficiently on biodiesel blends up to B20.

The 336F XE uses three building block technologies to deliver outstanding fuel savings and performance. The Cat Electronic Standardised Programmable (ESP) pump smoothly transitions between the hydraulic hybrid power sources, the engine, and the accumulator to conserve fuel. The Adaptive Control System (ACS) valve optimises performance by intelligently managing restrictions and flows to control machine motion.

Instead of wasting kinetic energy during swing braking, the Cat Hydraulic Hybrid Swing System pressurises the accumulator to stop the machine and then uses that pressure when needed to accelerate the machine later.

According to Cat, the key ingredient is the ACS valve, which can be found only on the Cat brand. It is the “brain” of the system – one that independently controls machine functions and directs hydraulic energy where operators need it precisely when they need it.

Because the ACS valve is fully integrated with the pump and hybrid system, operators will experience the same extraordinary control, hydraulic power, and lift capacity they get from traditional Cat machines with the added benefit of dramatically reduced fuel consumption.
