Hyundai 120t excavator on major European demolition projectPublished 15/9 at 12:23
Démolition et terrassement XL Sàrl from Nidderkuer, Luxembourg, has been using the largest 120t Hyundai excavator, the R1200-9, on a major demolition project in Luxembourg City.
Fitted with a 7t hydraulic breaker the Hyundai excavator, the first one in Europe, is breaking out concrete foundations to make way for a 35m deep, six storey underground car park
The excavator was sold by Hyundai dealer for Belgium and Luxembourg, HMB. “The owner of Démolition et terrassement XL Sàrl, Carlos Alberto Rodrigues de Sousa, came to see us at Bauma in 2016, where we concluded the deal,” said HMB joint owners Paul Verbiest and Tom Haesevoets. “He was already familiar with the Hyundai range and has 12 Hyundai machines in his fleet. For this special project he was looking for a machine of substantial size to complete the task. What really convinced him was the combination of the quality and efficiency of the Hyundai machines, a good price and our excellent service and good relationship with his company. We are very proud to contribute to this project.”
The 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 of 710mm, 800mm and 900 mm in width. For this demolition job, the client was looking for narrow shoes, which will also be used for the excavator’s next assignment at a quarry near Luxembourg City.
The excavator has a computer aided power optimization system ensuring optimum performance from the engine and the two hydraulic pumps. The different power modes serve specific working loads. The system also has auto deceleration and a power boost. The LCD display monitors engine speed, coolant and hydraulic oil temperatures and the diagnostic error codes. At the push of a button, the operator can select boom/swing priority and power mode settings.
The operator has the option of selecting the power mode appropriate to the job, materials or attachment. The three power modes ensure maximum engine performance, high speed and optimum fuel efficiency. Power mode ensures maximum machine speed and power for maximum productivity. Standard mode provides reduced engine speed for optimum performance and improved fuel economy. Economy mode adapts flow and engine power to specific load conditions for maximum fuel efficiency and controllability.
