New Factory-Installed SVAB/Steelwrist Options for Doosan Wheeled Excavator Range
4 May 2018
At Intermat 2018, Doosan DX165W-5 16.5 t and DX170W-5 17 t wheeled excavators are being demonstrated, both fully equipped with new factory-fitted SVAB control system/joystick and Steelwrist quick coupler/tiltrotator options. The DX165W-5 is being shown in the Steelwrist demonstration area (E5 L 041). The DX170W-5 is working in the Doosan demonstration area (E2 D 047) outside Hall 5b, inside which the company’s static display can also be seen.
The focus on the Doosan wheeled excavators is to launch the new factory-installed SVAB/Steelwrist options now available for the first time on the Doosan wheeled excavator range through Doosan Smart Solutions. Doosan is introducing the following factory-fitted options and attachments from SVAB/Steelwrist not only on the DX165W-5 and DX170W-5, but also on the company’s DX140W-5 14 t and DX160W-5 16 t wheeled excavators:
SVAB control system
Automatic digging brake
Gateway to MSC control system
Steelwrist quick coupler and tiltrotators
S60 quick coupler with front pin lock
Direct fit X18 with S60 coupler
Direct fit X18 with S60 coupler with gripper
Sandwich X18 S60/S60
Sandwich X18 S60/S60 with gripper
Direct fit X20 with S60 coupler
Direct fit X20 with S60 coupler with gripper
Sandwich X20 S60/S60
Sandwich X20 S60/S60 with gripper
The SVAB/Steelwrist installation on the four wheeled excavator models enhances field support for Doosan dealers and customers, providing a complete CE-marked excavator that fully meets the customer’s requirements, saving on the time and costs required for installation normally carried out at the dealer’s facilities, with the additional advantage of integrated machine control systems for 3D work.
Tiltrotators are an increasingly popular attachment for excavators. Although the tiltrotator was first invented in the late 1980s, the technical development pace is still extremely high today. The market penetration varies a lot between the most advanced markets where above 90% of excavators between 3 and 30 t have a tiltrotator, to start-up markets where only the true first movers looking for increased efficiency are active.
Experienced operators estimate the productivity improvement to be between 20 and 35%, depending on the type of job involved. Existing jobs can be done faster; new types of work can be undertaken with the tiltrotator in place and there is less need for support staff on the ground.
Doosan Wheeled Excavators
The 16.5 t DX165W-5 Stage IV compliant wheeled excavator from Doosan is a short tail machine that is perfect for jobs in tight spaces, particularly in urban areas or on narrow roads with heavy traffic. Tailored to meet specific customer demands, the new DX165W-5 has been designed to ensure it offers the same high performance as the market-leading conventional Doosan wheeled excavator models.
The DX165W-5 is built with the same undercarriage as the Doosan DX160W-5 Stage IV model, providing an optimal centre of gravity thanks to the long wheel base and the ideal weight distribution. The DX165W-5 also features a new generation of heavy duty ZF axles offering the best possible dynamic and static axle load. From the standpoint of performance, the DX165W-5 has the same forces and lifting capacities depending on the application as the DX160W-5 model. The DX165W-5 can therefore lift 5.87 t at 4.5 m reach over the front (at 3 m high) and 4.28 t over the side. This is a better performance than any other short tail wheeled excavator in its class.
The 17 t DX170W-5 Stage IV compliant wheeled excavator provides high performance in every area, combining enhanced comfort and controllability together with new features to boost fuel efficiency, uptime and return on investment, with a focus on increased power, robustness and agility.
From the standpoint of performance, the DX170W-5 has 10% more engine power, 5% more engine torque and 5% more traction force compared to the previous generation model. The swing speed can now reach 10.8 rpm/minute and swing torque has been increased by 4%. Main pump capacity has increased by 9% and thanks to the increased pressure in the new Negacon hydraulic system, there is a significant increase of 10% in the bucket force and 3% in the arm force.
The extra 220 kg in the weight of the counterweight in the DX170W-5, coupled with increases of 4 and 5 cm in the machine width and wheel base, respectively, have drastically increased lifting capacities while improving stability and comfort when driving. The over the front lifting capacity has increased by 10%, whilst the lifting capacity over the side has gone up by 6%. Other important aspects include the new ‘CabSus’ cab suspension system which reduces vibration by 20% and a massive 4 dBA reduction in cab noise, further increasing safety and comfort for the operator.
