DOOSAN has forecast that the company will produce 50 to 60 100-tonne excavators in 2023.
This follows the news that the first Doosan DX1000LC-7 100-tonne crawler excavator sold in Europe has gone to Estonia-based Kiviõli Keemiatöötus (KKT), part of the Alexela Group.
Supplied by INTRAC Group, the digger has joined the existing Doosan DX800LC-7 80-tonne and DX490LC-7 50-tonne models already working at KKT’s oil shale mine at North Kiviõli.
Doosan revealed the purchase decision was based on the performance of the DX800LC-7, with which KKT is said to be burning 10 litres per hour less fuel than competitor machines for the same production output.
Powered by the new stage V version of the Perkins 2806J diesel engine, the model provides a high power output of 469 kW (629 HP). This is combined with a Virtual Bleed Off (VBO) hydraulic system (D-ECOPOWER+), providing what Doosan said is a ‘best-in-class’ hydraulic flow of (3 x 523) – 1569 l/min and a high system pressure of 360 bar.
The DX1000LC machine category has already proved popular in other markets, with the largest volumes in south east Asia, China and Latin America. Doosan has delivered 35 units so far and now builds both the 80 and 100-tonne models on the same production line. The capacity has been increased to ten units a month to meet demand for both machines.
