- 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
