The DL280-5 is the latest unit in the high-performance 12-model wheeled loader range of operating weights from 12-35 tonnes. It also comes as the company celebrates a milestone – 400,000 units sold in Doosan’s 40-year history.
The front lift arm of the DL280-5 is powered by a closed centre hydraulic system with a 210 litre/min axial piston pump for maximum hydraulic performance without producing excess capacity. This saves fuel and extends the lifetime and reliability of vital components, says the company.
The DL280-5 features Z-bar kinematics with a simple lifting piston system designed for heavy-duty applications. The breakout force of 145kN is combined with a constant bucket angle that is maintained throughout the range of movement. Bucket angles are also optimised in the travelling position and at ground level.
The lift arm benefits from an automatic Load Isolation System (LIS) - often called ride control - a standard feature to improve ride quality and operator comfort. The speed for automatic activation of the LIS system is fully adjustable by operators.
The DL280-5 is powered by the 5.9 litre Doosan DL06 diesel engine which provides high torque, performance and durability in this and other models in the Doosan range. The engine power is managed by three working modes - ECO, Normal and Power - to ensure the best torque and power for the toughest work conditions with the best fuel efficiency.
As standard, an auto shut-down reduces the idle time of the engine, to prevent the over-consumption of fuel and wasted operating time. Operators can easily set the timing for this function on the LCD display in the cab.
In common with the five larger Doosan wheeled loaders - the DL300-5, DL350-5, DL420-5, DL450-5 and DL550-5 - the DL280-5 has a wide range of new safety and ergonomic features as standard.
