Doosan claims high versatility for its latest wheeled excavator

According to the firm, the DX100W-7 offers a high performance solution for customers looking for a wheeled excavator for urban and road maintenance applications. The DX100W-7 offers productivity and can operate in very restricted areas, with the option of four wheel steering and a crabbing mode, with two wheel steering as standard.

Doosan says that the machine offers safety and performance, with an integral 1.35tonne counterweight ensuring stability for lifting work. In combination with the articulated boom and long arm, this provides a greater working range than other machines in this class. The counterweight also has a novel design, offering good maintenance access from the rear of the machine and from ground level.

The articulated boom ensures that the operator is able to position the machine as close as possible to trucks during loading. In addition, the DX100W-7 offers high lifting capacities and digging forces, as well as satisfying a requirement in some markets for a wheeled excavator with a travelling height of under 4m.

Other safety features can be found in the state-of-the-art ROPS cab on the DX100W-7, where the operator can use the touch screen to browse machine settings, including the view from the standard side and rear view cameras. The machine is available with an optional 360° all-around view camera, linked with an optional ultrasonic detection system.

With 75kW of power at 2000rpm provided by a Doosan D34 G2 Stage V engine, the DX100W-7 offers high output, hydraulic flow and traction force for this class. The high flow from the smooth and precise hydraulic system can be used to drive all kinds of attachments. In addition, the DX100W-7 has two different pumps providing independent hydraulic flows for the transmission and to power hydraulic tools on the front end.  

The D34 engine offers a new solution to exceed Stage V regulations without exhaust gas recirculation (EGR), that boosts the quantity of air available during combustion, increasing the temperature of the process and greatly reducing the amount of particulates produced. This is combined with efficient DOC/DPF+SCR after-treatment technology to ensure minimal emissions. An enhanced cooling system offers many advantages such as higher fuel efficiency, less noise and increased durability.

An improved and robust chassis is used in the DX100W-7, featuring a new type of pinning system, compatible with both front and rear undercarriage attachments and designed for mounting the optional four wheel steering system. The new chassis design ensures that attachments can be added and exchanged without modifying the frame.   

The new DX100W-7 model is factory-installed as standard with Doosan’s state-of-the-art DoosanCONNECT TMS 3.0 wireless fleet monitoring system. The DoosanCONNECT system offers a web-based fleet management solution which monitors the performance and security of machines and promoting preventative maintenance.
