Doosan Construction Equipment has launched the new DX19 1.9-tonne mini-excavator. Providing a unique combination of high performance and compactness, it is designed to offer increased productivity, excellent operator comfort in a large and easily accessed cab, and maximum durability and serviceability.
The optimized hydraulic system in the DX19 mini-excavator makes the best possible use of the engine power available from the Kubota D722 diesel engine, providing an output of 9.9kW at 2500rpm (ISO 9249). This results in fast cycle times, which are combined with smooth control of class-leading breakout forces, including a digging force over the bucket (ISO) of 20.8 kN.
Equipped with a cab, rubber tracks, long blade and bucket, the DX19 has an operating weight of 1894kg. With the long arm, the maximum digging depth of the DX19 is 2565mm, the maximum dump height is 2693mm and the maximum reach at ground level is 4214mm. This working range provides maximum performance and versatility in operating a wide range of attachments, and the overall smoothness of the hydraulic system is further enhanced by boom and arm cylinder cushioning.
The high lifting capacity and superior dumping height offered by the DX19 ensure that loading trucks is an easy process, while the reach at ground level reduces the need to keep repositioning when digging. An optional certified ‘object handling package’, which consists of a safety valve for the boom and for the arm, a hooking device and an overload warning device, is also available for the DX19. The new model is towable on trailers with a capacity up to 2000kg, with transportability further enhanced by new tie-down points.
When fully retracted, the retractable undercarriage on the DX19 allows the machine to go through narrow spaces; and, when fully expanded, it provides optimum stability for the excavator, especially when working over the side. Expansion and retraction are simple and easy via a switch on the control panel. In addition, to help dustpanning on the front, the long dozer blade significantly enhances stability at the front of the excavator, allowing the operator to make full use of the breakout forces that the machine can deliver.
The DX19 is built around the operator and provides optimal ergonomics. The cab features large windows and narrow pillars to maximise all-around visibility, operator comfort and safety. The large door width offers convenient access, which is made even easier as the control console rises completely out of the way when the operator takes their seat. There is ample space for the feet with a flat floor for easy cleaning, with floor panels that can be easily removed for service purposes, ergonomic pedals and easy access to all controls, the storage box and to cup holders. In addition, when not in use, the foot pedals can be folded back to further increase room for the operator’s feet.
The control panel permits an easy check of the main parameters (including auto engine shut-down, auto glow plugs countdown, auto cab lights switch-off and RPM meter). Other features include an easy-to-operate gas spring-assisted light and rigid frame front window, keyless ignition for optimal safety, a battery kill switch for storage and to prevent theft, and an automatic slew brake for safe parking and transportation.
The use of highly durable materials ensures that the DX19 offers hard-wearing and robust performance. All components and design features are tested under extreme conditions, and the heavy steel gauge tailgate ensures extra durability and peace of mind while working.
The tailgate and side cover can be quickly opened to provide immediate access to conveniently located components such as easily cleaned side-by-side coolers and other daily maintenance and service points, reducing downtime to a minimum. Maintenance and service work is further simplified by the diagnostics on the new excavator, including the error codes displayed on the control panel and service tool connection.
