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
