New DX17Z Mini-Excavator Launched By Doosan. The new DX17Z mini-excavator from Doosan is ideal for rental and urban construction sites with limited space. It is designed for all types of applications that require frequent mobility, compact size, powerful performance and a comfortable working environment for continuous work on confined space sites.
The 1.7 tonne DX17Z is a Zero House Swing (ZHS) mini-excavator offering easy transportability and more functionality than a Zero Tail Swing (ZTS) mini-excavator, in that ZHS fully protects the front upper structure corners within the swing circle. As a result, ZHS functionality provides 320° of free rotation while working close to any object.
Best-in-Class Stability
The stability of the Doosan DX17Z is best-in-class compared to all other ZTS machines on the market as it is based on the following features:
• A retractable undercarriage – when fully retracted, the undercarriage allows the excavator 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 an electric switch on the control panel.
• Long dozer blade (optional) – as well as helping to perform dustpan operations, the optional long dozer blade also significantly improves front stability, enabling the operator to make full use of the breakout forces the DX17Z can deliver.
• Easy-to-operate durable blade extensions.
The extra stability is essential for making maximum use of the exceptional digging forces and lifting capacities available in the DX17Z. Optimum stability is achieved by fully expanding the retractable undercarriage and using the long dozer blade. With the firm foundation of optimised stability and lifting capacity, the DX17Z offers the highest versatility in operating a wide range of attachments.
With best-in-class stability, the DX17Z is ideally suited to picking up and placing heavy items with safety. In addition, the DX17Z can be supplied with an optional certified ‘object handling device’, which consists of:a boom load holding valve, arm load holding valve, hooking device and overload warning device.
The superior dumping height of the DX17Z makes loading trucks an easy process, while the reach at ground level means the operator does not have to reposition the excavator as often as other machines when digging.
Incorporating the architecture of a 2 tonne class hydraulic system, with a combination of variable piston pumps and a gear pump, the DX17Z’s unique hydraulic system makes the best possible use of the engine’s power. Fast cycle times, combined with smooth control of class-leading breakout forces, provide maximum productivity. Boom and arm cylinder cushioning – also unique in this machine class – enhance the overall smoothness of the workgroup.
Superior Operator Comfort
Comparing favourably with larger excavators, the DX17Z provides superior operator comfort for working hours at a time with protection, cover and excellent visibility provided by a large and spacious canopy; easy entry and exit; convenient space for the operator’s feet with ergonomic fold-away pedals; a flat floor for easy cleaning; smooth joysticks; access to all controls and cup holders.
The premium control panel makes it easy for the operator to access all vital information: auto engine shut-down, auto glow plugs countdown, auto cab lights switch-off, audible alarm (in case of malfunction) and the RPM meter. A battery kill switch helps prevent battery drain when storing, and is an effective way to prevent theft. An automatic slew brake ensures safe parking and transportation.
The DX17Z has a standard operating weight of 1749 kg and a maximum digging depth of 2249 mm. In accordance with European transport regulations, the maximum towable weight for a BE license is 3500 kg. With a transport weight of less than 1.65 tonne, the DX17Z is towable on trailers for 2200 kg of total weight. Transportability is made even easier with the integrated upper-structure tie-down points. An automatic slew brake helps facilitate safe parking and transportation.
Highly Robust and Easy to Repair
The use of highly durable materials ensures the DX17Z is highly robust and easy to repair. The design features are tested under extreme conditions – the heavy steel gauge covers and tailgate provide class-leading durability and peace of mind while working. Features include two-piece blade cylinder hoses to simplify replacement in case of damage; wrenchless hydraulic hose technology to help prevent leakage; proven boom and dipper-stick design; protected top-mounted boom cylinder; oversized cylinders for long lifetime performance; a new paint and surface treatment process for durability and extra residual value and a reinforced expandable undercarriage to maximise rigidity.
Thanks to the large steel tailgate and openable side cover, all components for daily maintenance are easy to access, keeping downtime to a minimum. Daily maintenance and service points are conveniently located for easy and immediate access. The side-by-side coolers are easy to clean. Simple diagnostics are used on the DX17Z, with error codes displayed on the control panel and service tool connection. The floor panels can also be removed rapidly for service purposes.
