- Improved comfort with low operator sound levels.
- Improved spectator sound levels and optional low sound packages.
TOP-TIER SERVICE AND SUPPORT
- Easier access and in a controlled environment; electronics bay is located inside the cab.
- Focused on safety with ground level or platform access to most major components.
- Ground level: emergency shutdown, battery disconnect, and jump start.
- Quick visual inspection and minimize fluid contamination with sight gauges for coolant, transmission, and hydraulic oil.
- Electronic air inlet restriction indicator.
- Designed for ease of service and inspection.
– Hydraulic oil cooler, fuel cooler, and condenser grouped together
– Centralized grease points - Operators and technicians can resolve any problems before failure using Vital Information Management System (VIMS).
POWERFUL EFFICIENCY
- Powerful, responsive Cat® 7.1 engine is designed for maximum fuel economy and increased power density.
- Reliable performance and low emissions.
- High productivity with optional four-way tilting blade.
- Two engine options available that meet U.S. EPA Tier 4 Final and EU Stage V emission standards or U.S. EPA Tier 3 and EU Stage IIIA equivalent.
- For the Tier 4 Final and Stage V option, the Cat Clean Emissions Module contains a diesel oxidation catalyst, diesel particulate filter, and Cat Regeneration System, utilizing SCR technology.
- Regeneration is completely automatic and does not interrupt the machine’s work cycle.
- Experience maximum responsiveness and control with Steering and Transmission Integrated Control System (STIC™).
- Conserve more fuel with the automatic engine and electrical system shutdown.
- Achieve greater momentum on grades and fuel savings by carrying that momentum through the shift points with the all new Advanced Productivity Electronic Control System (APECS) transmission controls.
- Operators experience less fatigue with throttle lock to maintain engine speed and reduce fuel burn.
PRODUCTIVITY WITH TECHNOLOGY
- Optional Cat Compact 3D mapping technology combines advanced compaction measurement, in-cab guidance, and reporting capabilities to help you consistently meet compaction targets fast, uniformly, and in fewer passes – saving on fuel and the cost of unnecessary rework.
- Cat Compaction Control with Machine Drive Power (MDP) is an energy-based measurement system that correlates compaction with rolling resistance to provide an indication of soil stiffness.
- Link technology (standard) provides access to machine location, hours, fuel consumption, idle time, events, and diagnostic codes through the online VisionLink® interface.
OPTIMIZE COMPACTION
- Chevron tamping tip design provides greater ground pressure, more compaction, excellent traction, and a smooth ride.
- Symmetrical tamping tip pattern results in equal compaction in forward or reverse. Tips are full perimeter and replaceable. The tip is welded to a base assembly, then welded directly to the drum.
- Each wheel has two cleaner bars to keep the drums free of carryover dirt, regardless of rolling direction so efficiency is maximized.
- The adjustable cleaner bar tips (standard or abrasive type) are heat-treated and direct-hardened cutting edge steel to increase wear life, which translates into lower operating costs.
