Product Feature
Efficiency
Engine, hydraulics, and work tool integration are optimized to minimize power losses and increase overall machine efficiency
Steady state high idle speed and U.S. EPA Tier 4 Final technology reduces fuel consumption
Larger hydraulic pump allows engine to operate at lower rpm with increased performance to maximize efficiency
Component layout and back-to-back main hydraulic control valve reduces oil flow restrictions and aids in greater fuel economy
Machine designed for integration and optimization with SATCO® work tools and Cat® grapples
Powerful, multi-functioning hydraulics, combined with strong machine performance ensure work tools function quickly and fluidly to complete work faster
Performance
Cat C7.1 ACERT™ Tier 4 Final engine with increased horsepower maintains maximum performance under load
Strong hydraulic horsepower for efficient implement performance and greater productivity
An increase in swing torque of 18 percent, provides added power to move trees, which enables more efficiency and productivity
Heavy lift mode features increased lift capacity to handle larger payloads with improved control
Stability
Wider undercarriage, by 203 mm (8 in), improves stability for increased lift and swing capabilities
Heavy duty counterweight as standard equipment ensures machine platform is stable in varied applications
Application Versatility
Boom arrangements and hydraulic systems for specific applications enable more effective road building, loading, processing, shoveling, or millyard stacking
New track options meet shovel logging and low ground pressure application requirements
Ground saw hydraulics are available for log loader applications
Purpose built processor cab that includes 19 mm (0.75 in) front windows
Reliability and Durability
Variable pitch, reversing cooling fan maintains optimum fluid temperatures in heavy duty forestry applications
Cooling capability increased 12 percent for trouble-free operation
High-wide carbody features double-supported carrier rollers, reinforced idler mounts, heavy-duty top hat, extra gussets, and thick doubler plates for structural integrity in severe applications
Larger 203 mm (8 in) pitch Positive Pin Retention 2 links (329 HEX) provide greater life in variable forestry working conditions
Purpose-built upper frames provide increased life with box section members, thick doubler plates, reinforced swing drive mounts, rugged door components, and 5 mm (0.2 in) sheet metal
Linkage configurations incorporate internal baffle plates, large box sections, and thicker plating to increase service life
Validated and proven excavator technologies ensure overall machine reliability
Serviceability
One-piece engine hood design, with two opening angles, allows easy access to engine and cooling compartments
Side-by-side engine and hydraulic coolers provide easy access for cleaning, while reduced cooling fins per inch allows better debris flow-through to reduce clogging potential
0.28 m3 (10 ft3) of storage space at ground level, gives ready access to tools, equipment, and supplies that operators use daily
Operator Comfort and Technology
Fully adjustable, air ride cab seat that includes heating and cooling capability for comfort and reduced operator fatigue
LED lights increase visibility
Cat Product Link™ allows for remote location of a machine and enables tracking of fuel consumption and other events
Work Tools
Both machine models are optimized for a wide variety of processing and harvesting heads, grapples, heels, quick couplers, and thumbs
