Doosan Infracore Construction Equipment will take the covers off five new wheeled loaders at INTERMAT. The DL300-3, DL350-3, DL420-3, DL450-3 and DL550-3 large wheel loaders – with bucket capacities from 3.0 to 5.5cubic metres - get Scania SCR diesel engines that meet stage IIIB emissions regulations.
Doosan's DL420-3 Large wheeled loader live at INTERMAT
The DL300-3, DL350-3, DL420-3, DL450-3 and DL550-3 large wheel loaders – with bucket capacities from 3.0 to 5.5cubic metres - get
The DL300-3 and DL350-3 wheel loaders will use Scania’s nine litre DC09 five-cylinder engine giving a maximum rating of 202kW at 1,800rpm. The larger three models will get Scania’s 13-litre DC13 six-cylinder diesel engine. Maximum power outputs are 264, 264 and 283kW respectively, all at a leisurely 1,800rpm.
All models get a new five-speed ZF transmission with closer ratios, which prevent a high variation in engine speed with every gear change.
Models also get a torque-converter-cut-off (TCCO) system, which provides a direct mechanical connection between the engine and transmission.
This torque converter lock-up works from gears 2-5, and has the potential to deliver increased traction with lower fuel consumption.
