Doosan Infracore (UK) has announced the introduction of the DL350 wheeled loader which extends the current range to a total of eight models from 1.5 to 5 cu m with an emphasis on performance, reliability, comfort and ease of maintenance.
The new 3.5 cu m model is powered by a Doosan DL08 7.6 litre common-rail turbocharged diesel engine with an exhaust gas recirculation system developing 173 kW (235 hp). This powerful engine also provides an impressive maximum torque of 1100 Nm at just 1200 rpm for optimum traction and loading force. In fact, the DL350 offers an excavation force of almost 17 tonne, the highest in its category, making it ideal for stripping the hardest materials.
Like all Doosan wheeled loaders, this new model is equipped with a ZF Powershift transmission and limited slip differentials as standard as well as hydraulically controlled, multi-disc oil-immersed brakes.
Doosan has always taken great care to provide a comfortable working environment for the operators of its equipment and the DL350 is no exception. With an internal noise level of only 69 dB(A), electronic heating and air conditioning and a roomy interior with plenty of storage space the new model's cab ensures a perfect environment for a full day's productive work.
Anti-pitch control and a third hydraulic control valve are fitted as standard and the machine has a choice of two working modes - one standard and one economic - which allow the operator to adapt the machine to the work in hand and optimise the fuel consumption/productivity ratio.
Another fuel reducing feature is an electronically controlled cooling fan which is speed dependent on coolant/transmission temperature. This fan, which also helps to reduce noise, is reversible and tilts to facilitate easy maintenance when operating in dusty conditions.
The new model has extended intervals between oil and filter changes plus a monitoring system that can be accessed via a portable computer to enable transmission status to be verified and various other adjustments to be made including, for example, compensation for clutch disc wear without requiring disassembly.
