Hyundai Heavy Industries Europe has launched a brand new midi excavator in the 6 tonne weight range. The 5.9 tonne new R60CR-9A short tail swing (STS) model replaces the previous R60CR-9.
The R60CR-9A is powered by the fuel efficient; Stage IIIB certified Yanmar 4TNV98C engine which provides proven, reliable power. This engine is electronically controlled for optimum fuel to air ratio and clean, efficient combustion and provides low noise, anti-restart features. The Yanmar 4TNV98C Tier 4 final / Stage IIIB compliant diesel engine provides 48.3 kW of power, a maximum torque of 24 kgf .m and offers a 10% increase in power over the previous model. The new excavator offers higher fuel efficiency with a 14% reduction in fuel consumption.
A larger and more efficient radiator and oil cooler provides increased cooling capacity by higher air flow rate. The cooling capacity in the –9A is 30% higher than the -9 Series.
The R60CR-9A ‘s advanced hydraulic system includes optimized matching between the joystick and main control valve which improves fine control and smoothness of operation. An arm flow summation system provides energy savings, reduced cavitation and increased speed. To improve safety and avoid boom drift the R60CR-9A is equipped with an integrated boom holding system.
The R60CR-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 when working on a slope.
The R60CR-9A’s short tail swing radius allows the operator work in confined areas such as close to buildings on roadways, and in urban areas. This compact radius design provides
easy and efficient operation in any limited space working environment.
The new midi excavator offers arm digging force to 26.5kN and a bucket digging force of 40.9 kN in the short arm version. The machine has an operating weight of 5. 900kg’s and a maximum digging depth of 3,570mm. The R60CR-9A cabin structure has been fitted with stronger but slimmer tubing for added safety and improved visibility. Low-stress, high strength steel is integrally welded to form a stronger, more durable upper and lower frame.
All control devices are arranged for higher productivity and improved operator comfort. Efficient and ergonomic controls allow an operator to control the machine in any working environment. A safety lever on the left-side console is provided to prevent exiting the cabin while hydraulic controls are live.
The advanced new LED cluster allows the operator to select his personal machine preferences. The monitor displays engine rpm, engine oil temperature, water temperature and information for all electronic devices. 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 the password.
The R60CR-9A features the legendary Hyundai -9A cab, which has been well received by operators around the world. Noise reduction in this cab is of particular note and is 3dB(A) lower than the -9 Series. Cab comfort doesn’t get much better than this, starting with the fully adjustable suspension seat and armrests which can accommodate operators of all sizes. New joystick consoles are adjustable in height at the push of a button, ensuring they are always in the right position for the operator and ensuring less fatigue during long working days.
The fully automatic high capacity air-conditioning system maintains a comfortable working environment throughout the day. Other cab amenities include a transparent polycarbonate glass sun roof, with integrated easy to control sun visor, and an advanced audio system with USB player, AM/FM stereo and MP3 capabilities, plus remotely located controls, that make it so much easier for the operator to control. In addition, operators can talk using a built-in Bluetooth hands-free mobile phone system.
