YANMAR TIER 4 FINAL ENGINE
R55-9A fetures a tier 4 final Yanmar 4TNV98C Water-cooled, 4-cycle, 4 cylinders in line, direct injection, low emission diesel engine with 65.1 HP (48.5 kW) at 2,400 rpm.
BOOM SWING
The R55-9A’s boom swing function is designed for efficient work in congested residential and urban areas. The boom can be offset left or right within an operating range. Plus, increased swing torque provides enhanced operating capability on
the slope.
DOZER BLADE
All 9A series excavators feature as standard equipment a large dozer blade that provides added versatility, efficiency and stability.
STANDARD TAIL SWING
The R55-9A is equipped with a standard tail swing which provides greater stability and lifting capacity than a traditional zero tail swing excavator. This provides additional versatility on the jobsite, especially when using auxiliary attachments.
Reliability
RELIABILITY & DURABILITY
Reliability
Hyundai construction equipment is precision designed with trusted and proven components and systems from leading OEM’s. The R55-9A is designed to be rugged and reliable for longer up time, reduced operating cost and improved productivity.
Durability
Hyundai construction equipment is manufactured with the highest grade of steel due to Hyundai’s dominance in the steel and shipbuilding industries. Rigid cycle testing, heat testing, vibration testing and shock load testing is conducted in the design and manufacturing process of all new models insuring optimum durability and reliability.
Convenience
Convenience
Monitor
The advanced new LCD cluster allows the operator to select his personal machine preferences. Button selections are provided for auto idle mode, max power mode, and travel speed. A security feature is also provided to prevent the machine from starting without a proper password.
SUSPENSION SEAT
The R55-9A operator’s cab is designed for a comfortable operating experience. An ergonomically designed suspension seat, adjustable arm rests and a spacious environment helps to minimize operator fatigue.

CENTRALIZED LUBRICATION
Centralized lubrication bank for faster, easier service and maintenance.
LONG-LIFE COMPONENTS
9A series excavators were designed with bushings designed for extended lube intervals (250 hrs) & polymer shims (wear resistant, noise reducing), extended-life hydraulic filters (1,000hrs), long-life hydraulic oil (5,000hrs), more efficient cooling systems and integrated preheating systems which extend service intervals, minimize operating costs and reduce machine down time.
EASY ACCESS
The R55-9A was built with accessibility in mind. All covers and hoods were built for complete open access. Regular service and maintenance is easy and convenient with the R55-9A.
DURABLE COOLER
Radiator and oil cooler with square wave and corrugated wave fin design reduce clogging and improved clean out and durability.
