Démolition et Terrassement XL from Luxembourg has been using the largest capacity Hyundai excavator, the R1200-9, on a major demolition site in the financial heart of the city.
This is the first Hyundai machine of this size to be sold in Europe. The gigantic site, once complete, will host offices for the Bank of China.
The 120-tonne excavator, powered by a 567kW turbocharged diesel engine, was designed for heavy earthmoving, stationary digging and long-reach demolition duties.
The standard equipment includes double grouser shoes measuring 710, 800 and 900mm in width. But for this particular demolition job, the client was looking for narrow shoes. Its engine power is 567kW/760hp (1,800rpm) and bucket capacity is 6.7cu m.
A computer-aided power optimisation system ensures optimum performance from the engine and the two hydraulic pumps. Different power modes serve specific working loads, and the system also features auto deceleration and a power boost.
The operator can select the power mode appropriate to the job, materials or attachment to ensure maximum engine performance, high speed and fuel efficiency.
It has a smart function for auto boom/swing priority, which adapts the ideal hydraulic flow balance for boom and swing operation to the application at hand.
