Rock and ‘roll’: Doosan unveils new wheeled excavator

A new 5t Stage V compliant wheeled excavator – dubbed the  DX57W-7 –  has just been launched by Doosan.

In addition to a new Doosan Stage V engine, the DX57W-7 has other new features, which the Korean company says allow for “increased comfort, convenience and connectivity, whilst maintaining optimum performance, durability and fuel efficiency”.

The DX57W-7 has Doosan’s latest DoosanCONNECT system installed, which provides a telematics management system for the excavator, by collecting data from sensors on the machine.

Other standard features include a stereo system integrated in the gauge panel, with a Bluetooth streaming function, together with a USB charger in the cab.

The DX57W-7 also offers options of a new all-round view camera providing 360° views around the machine and ultrasonic detection of obstacles for increased safety in operation.

The DX57W-7 is powered by the 42.5 kW (57hp) Doosan D24 Stage V engine.

Equipped as standard in the single tyre configuration, the operating weight of the DX57W-7 equipped with a 0.175m³ bucket is 5.88t. A dual tyre configuration is available as an option.

The DX57W-7 offers two travel speed ranges, with a maximum travel speed of 30kph.

In terms of applications, in addition to the normal trenching and groundwork jobs, Doosan says that the stability and lifting capacity of the DX57W-7 allow the excavator to be used for applications such as truck loading and unloading and moving pipes and materials in the working area.

For operations involving lifting work, the DX57W-7 is equipped with an overload warning device as well as safety valves in the boom and dozer blade hydraulic systems.

The undercarriage consists of a rigid, welded frame, while the routing of hydraulic lines, protection for the transmission and heavy duty axles “make the undercarriage ideal for wheeled excavator applications”, the Korean manufacturer claims.
