ALL-ROUND VERSATILITY AND IMPROVED FUEL EFFICIENCY

- Developed with the concept of providing optimum value to the end-user. The DX89R-7 (reduced tail swing) hydraulic excavator offers additional value to the operator. Namely:
- Increased production and improved fuel economy achieved with an electronic control for the hydraulic system and for the engine.
- Improved ergonomics, increased comfort and excellent all-round visibility, ensuring a safe and pleasant working environment.
- High-performance materials, combined with new methods of structural stress analysis, improve reliability and increase component life expectancy, thus reducing running costs.
- Reduced maintenance increases the excavator's availability and lowers the operating costs.
- The advanced hydraulic system, combined with the powerful engine, provides the biggest digging and tractive forces for efficient operation. As a result, the DX89R-7 provides outstanding performance, work efficiency
and the ability to adapt to any work environment.
- The DX89R-7 has a powerful and eco-friendly heart, always providing high operating efficiency and pleasant working conditions. Thanks to the turbo charger, the engine output and torque power are much stronger. This engine is also well-known for excellent fuel efficiency and reliability with long service life.
- The boom swing function allows you to work in very narrow areas.
- With its power, efficiency, and increased digging force, this machine can handle every job site condition.
- Welded, unitized blade provides durability even under harsh working conditions.
- The travel motors automatically return to high speed after downshifting under load. This allows smoother turns and easier dozing work.
- Reinforced castings, forged steel pivot points, and reinforced heavy-duty arm and boom withstand high-impact materials. Large, robust boom and arm cylinders for smooth, powerful operation. Advanced pin & bushing technology.

THE IDEAL WORKSPACE FOR OPERATING IN HIGH COMFORT

- The DX89R-7 is designed to provide you with the best possible working conditions. The sophisticated state-of-theart ROPS cab is pressurized and ISO-certified for your safety. Standard LED cab and boom lights, large side mirrors, rear-view and AVM 360° cameras, as options, give you full visibility of the machine’s surroundings. Other standard safety features include: automatic overheating alarm warning, low oil pressure sensor, and engine emergency cut-off switch.
- Comfortably seated thanks to a high-quality heated seat with air suspension, you benefit from a clear all-round view of the work site and have easy access to several storage compartments. Pedals, joysticks and armrests have all been designed for operator comfort and efficiency. Noise and vibration levels are remarkably low, and the effectiveness of the air conditioning and automatic climate control has been increased significantly. These features allow you to continue working for hours on end without feeling tired and maximize your productivity and return on investment. Finally, thanks to the hands-free system, you won’t miss any important call, and you'll stay available to your customers as you operate the machine.
- Highly sensitive & low-effort joysticks and clear convenient controls enable you to work safely, smoothly & confidently with minimum effort. Proportional auxiliary flow means precision control, smoothness & efficiency when using attachments.
- The wide 8" touchscreen provides easy scrolling through the different menus, including power settings and auxiliary hydraulics settings. It also allows you to connect a Bluetooth device or listen to your favorite radio station.

SIMPLE MAINTENANCE FOR MAXIMUM UPTIME

- Top quality materials, the most advanced computer-aided design, and endurance testing under the most demanding conditions ensure your excavator keeps on performing. The DX89R-7 has been designed for low maintenance with longer intervals – resulting in more machine availability – while skilled Develon-trained technicians are available to provide extra support when needed.
- Using finite elements and 3-dimensional computer simulation, the shape of the boom has been optimally designed for better load distribution throughout the structure. This enhancement, combined with increased material thickness, limit element fatigue for improved durability and reliability.
- A battery cut-off switch makes it easy to disconnect the battery during long-term storage.
- The hour meter display can be easily checked from ground level.
- For extra accessibility and servicing convenience, all filters (engine oil filter, fuel pre-filter, fuel filter and pilot filter) are accessible from ground level.
- Placing MCV in the middle of the machine improves its maintainability and work visibility.
- Fine mesh on the side doors and on the cooler itself filters the intake air going to the cooler for better cooling performance and reduced maintenance.
- The rubber tracks offer greater non-slip and grip capabilities and are less harmful to sidewalks and road surfaces in urban environments. These rubber shoes can be easily installed or removed with the idler, sprocket and other main parts. The reinforced seal type upper rollers make our traveling system even more durable. The result: longer traveling time and distance, especially in harsher environments. Because the Lower Roller Steel/Rubber shoes are dual flange type, they can be replaced without needing to replace components . ensuring increased lateral lifting force.
- The engine compartment is designed for easier service, and the sturdy sound-proofing inside the engine cover reduces the noise to provide a more comfortable environment for the operator and those working around the machine. The clips make disassemblingeasy and convenient.
- Hydraulic oil level can be easily checked through the gauge on the right side of the hydraulic tank.
- Integrated grease piping is designed for easy maintenance of the swing bearing and boom swing cylinder.
