Develon, formerly Doosan Construction Equipment, has unveiled the Next Generation ‘-9’ Smart Crawler Excavator range at Bauma. Develon has revealed two new -9 excavators being presented for the first time in Europe at a special ceremony on the company’s stand. The 23 tonne DX230LC-9 crawler excavator is part of the static display and the 26 tonne DX260LC-9 model has shown its paces in the demonstration area throughout Bauma.
Develon has improved the new -9 models. The improvements can be categorized into four key areas:
- Safety & Smart Features
- Operator Convenience & Cab Comfort
- Increased Productivity & Efficiency
- New Product Design
Safety & Smart Features
The Smart All-Around Viewing Monitor (SAVM) is an AI-based Object Detection technology to effectively identify both moving and stationary individuals in close proximity to the machine. Upon detection, the system promptly alerts operators through a combination of visual signals and audible alarms on the monitor, ensuring a heightened awareness of the surrounding environment.
The Advanced Lift Assist system provides clear and immediate visibility of the machine’s tip-over possibility, serving to mitigate accident risks and keep the operator focused on driving.
The innovative E-Stop and Virtual Wall functions prevent accidents the operators are not aware of. To help ensure safety, the area surrounding the machine is clearly defined into specific zones: a yellow warning zone (Zone 2) and a red danger zone (Zone 1).
The SAVM and E-Stop system utilize 6 cameras and 3 radars and work in 3 stages with a detection range of 13 m and 330°:
- People detection from 13 m range
- Warning and slowing down the speed from 6 m
- Stopping the machine from 3 m (swing and reverse)
The E-Stop is an safety feature designed to control or halt a machine’s movement, such as driving or swinging, in cautionary or dangerous areas, thereby ensuring operator safety.
Operator Convenience & Cab Comfort
The -9 machines feature an ergonomically designed user interface that enhances ease of use. It includes a thoughtfully arranged keypad, a jog shuttle and a monitor that is easily accessible, among other features. One standout aspect is the wide and intuitive 12.8-inch monitor, available in dual configurations for diverse needs. Additionally, the machine comes with a comfortable seat that has a built-in cooling function, as well as a cab designed for improved visibility, providing operators with best-in-class convenience in the industry.
Develon provides customized solutions through its FEH (Full Electric Hydraulic) system on the -9 models.
Operators have tuning options and can customize joystick sensitivity and more to match their driving habits and job site needs.
One of the standout features of this service is the Digital Key, a sophisticated Bluetooth combined with high speed Ethernet network (5G) communication-based tool that empowers users to unlock the cab door, ignite the engine and adjust the air conditioning settings from the MY DEVELON app, all without the need for a physical key. This remote-control functionality allows for efficient management of the machine from a distance.
Furthermore, the platform enables users to view and analyze operational history, aiding efficient equipment management, especially in fleet or rental scenarios.
Productivity & Efficiency
Compared to the previous -7 models, the new -9 machines provide a 12% increase in productivity and an 8% reduction in fuel consumption.
The incorporation of a Full Electric Hydraulic (FEH) control system—featuring electronic pumps, electronic Main Control Valves (MCV), and electronic Relief Control Valves (RCV)—has resulted in fuel savings of between 1700 l (for the DX230LC-9) and 2700 l (for the DX260LC-9) for every 1500 hours of operation compared to earlier models.
The innovative Breaker Assist technology prevents blank firing, which helps protect the excavator and its components while minimizing operator fatigue, leading to increased productivity. Additionally, the Auto Breaker function allows operators to perform breaking seamlessly without the need for continuous button pressing, further reducing operator fatigue.
The new -9 models are equipped with Develon’s advanced Prognostics and Health Management (PHM) technology. This technology continuously monitors key components like hydraulic oil, engine oil, pumps and motors, enabling timely predictions and proactive maintenance.
New Product Design
The external design truly encapsulates Develon’s vision of SMART construction equipment. Notable features include the industry’s first welcome light, strategically placed horizontal beacon lamps at the four corners of the cab’s upper surface, and signature lighting that adapts to the work environment by changing colour.
