By combining ACERT Technology with the new Economy Mode and Power Management, customers can balance the performance and fuel economy to suit their requirements and applications.
Maximum Versatility
A variety of work tools, including buckets, hammers, rippers are available for applications such as demolition, site clean-up, scrap processing, breaking up road surfaces and bedrock through Cat Work Tools.
Operation Station
Superior cab comfort and visibility provide an excellent working environment enabling productive day-long operation. The full-color monitor with graphic display features enhanced functionality to provide a simple, comprehensive machine interface.
Performance
The Cat C9 engine with ACERT Technology offers more engine power, and runs at lower speeds for better fuel efficiency and reduced wear.
Power Management
Flexible power modes allow an operator to balance productivity and fuel consumption needs to suite a wide range of applications.
Automatic Engine Speed Control
The two-stage, one-touch control maximizes fuel efficiency and reduces sound levels.
Engine Controller
ADEM™ A4 (Advanced Diesel Engine Management) electronic control module manages fuel delivery to get the best performance per liter of fuel. It tracks engine and machine conditions while keeping the engine operating at peak efficiency.
Cooling System
To reduce fan noise, the cooling fan is hydraulically driven with a variable speed control that manages fan speed to provide optimized cooling.
Air Cleaner
The radial seal air filter features a double-layered filter core for more efficient filtration and is located in a compartment behind the cab.
Fuel Delivery
The Cat C9 features electronic controls that govern the mechanically actuated unit fuel injection system. Multiple injection fuel delivery involves a high degree of precision; such high precision would translate into more work output for your fuel cost.

Robotic Welding
Up to 95% of the structural welds on a Cat Excavator are completed by robots. Robotic welds achieve over three times the penetration of manual welds.
Heavy-duty High Wide Carbody Design and Dedicated Track Roller Frames
X-shaped, box-section carbody provides excellent resistance to torsional bending. Robot-welded track roller frames are press-formed, pentagonal units to deliver exceptional strength and service life.
HDHW Undercarriage
The wide and durable Cat undercarriage absorbs stresses and provides excellent stability. Additionally, the high ground clearance is ideal in rocky environments, bringing the upper frame in a safer high position.
Rollers and Idlers
Sealed and lubricated track rollers, carrier rollers, and idlers provide excellent service life, to keep the machine in the field longer.
Long Undercarriage
The long undercarriage (L) maximizes stability and lift capacity. This long, wide and sturdy undercarriage offers a very stable work platform.
Tracks
The 340D L track links are assembled and sealed with grease to decrease internal bushing wear, reduce travel noise and extend service life lowering operating costs.
