Features
Performance
- The Cat® C4.4 ACERT™ U.S. EPA Tier 4 Final engine provides equivalent power (129.3 kW/173 hp) and optimized performance compared to C Series while minimizing overall fluid consumption
- Advanced controls manage pump and engine interface to optimize performance and fuel efficiency
- Leading hydraulic multi-functioning capability enables operator to lift, swing, and rotate grapple simultaneously without impairing performance
Efficiency
- Auto idle minimizes fuel consumption when machine is on and not actively working
- High capacity cooling system only pulls in cool external air to maximize efficiency
- Electrically controlled variable speed fan is modulated to provide cooling only as required, reducing fluid consumption
Comfort
- Smooth hydraulic controls and superior balance provide market leading comfort and controllability
- High capacity HVAC system provides dependable cooling and heating for maximum comfort
- Improved stabilizer controls to equalize stabilizer actuation resulting in optimized uniformity of footing in varying ground conditions
Safety
- Stabilizer movement alarm alerts bystanders of stabilizer movement
- Pilot enable alarm alerts bystanders when pilot function is engaged
- Ground level access of engine, fuel, pilot, and case drain filters as well as electrical service box
Durability
- Reinforced fabricated booms with optimized cross sections designed to withstand heavy side-to-side delimbing applications and maximize lift capability
- Field proven cooling system keeps engine and robust hydraulic system cool, extending component life
- Larger diameter pins feature heavy-duty plating for improved durability and excluder seals to retain grease and keep free of SP contaminant
Serviceability
- Single cylinder main boom has fewer parts to service than traditional dual cylinder lift system
- Standard electric fill pump for hydraulic oil is at ground level for safe, easy service
- Hinged doors provide industry-leading access to core components, daily check points, and service locations
Cat Work Tools
- Optimized Cat XT™-6 ToughGuard™ hose routings on GLK Series grapple designed to minimize loosening of fittings and improve hose life
- Larger GLK Series cylinder pins and bushings reduce bearing stress by 25 percent
- Available now in both a TW “Tapered Wide” and SN “Straight Narrow,” the GLK Series grapple is suitable for additional applications
- Standard hold valves on GLK Series log grapples improve log retention
- GLK Series grapples feature optional three port swivel which allows mounting of grapple saw
- DLK426 delimber knives now have larger diameter pins that reduce bearing stress by 12 percent
