Hyundai's a R60CR-9A crawler excavator on road duty in Cittareale, Italy
Hyundai Heavy Industries, in collaboration with the construction machinery manufacturers Italian dealer Hitex, recently supplied two machines for Earthquake clean-up duties in Italy.
The machines - a R60CR-9A crawler excavator and a HL757-9A wheeled loader were handed over to the Il Corpo Nazionale dei Vigile del Fuoco for four months at no cost.
It was August 24, 2016, when an early morning violent 6.2 magnitude earthquake shook central Italy and claimed 297 lives. The epicentre was located near Accumoli, 75km southeast of Perugia and 45km north of L'Aquila. Since then several earthquakes have followed, resulting in even more casualties and damage.
The machines were delivered to the headquarters of the Fire Brigade of the medieval town Cittareale in late October 2016. The town’s many historic buildings were almost completely destroyed or seriously damaged by the earthquake.
The HL757-9A wheeled loader is one of six models in the Hyundai's 9 series of machines with operating weight from 9-33.5tonnes, with bucket capacities of 1.8-6m³. The HL757-9A has a weight capacity of 14,700kg and a bucket capacity of 2.8m³. The operator can adjust the engine power and the timing of the automatic transmission and clutch disengagement based on the application and preference.
The engine benefits from three power modes - Power for heavy work – “standard” for general work and “economy” mode for light work.
The fully automatic transmission is equipped with self-diagnosis and low temperature protection – which is especially important for the machine working in areas such as Cittareale where winter temperatures regularly drop below freezing.
The Hyundai R60CR-9A compact excavator, like all machines in the A series, helps to maximise profitability by improving fuel economy and by delivering advanced maintenance functions and highly resistant components.
The machine has been designed for maximum precision and offers the operator the very best in handling and maneuverability. The flow rate of the pump decreases the hydraulic flow, when the controls are not in use, to reduce fuel consumption.
The fuel-efficient, Yanmar 4TNV98 engine 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.
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 hydraulic system includes an arm flow summation system, boom holding system and a swing parking brake for smooth and fine control. Other valuable features include a hydraulic damper in the travel pedal and a hydraulically lubricated swing reducer with a leak-free grease chamber.
