DEVELON -9 Series crawler excavators deliver the powerful arm and bucket forces needed on rugged construction and infrastructure projects for digging into tough materials or lifting and loading heavy materials. The counterweight adds stability when using heavier attachments. Select the one-touch power boost to amplify hydraulic power for more difficult digging tasks. A strong, productive swing torque allows the excavator to swing uphill with ease — improving backfilling performance. Fast cycle times help you complete work quickly and efficiently so you can move on to the next challenge.
Selectable power modes help you balance fuel consumption and machine power based on your working conditions. Choose from:
A fine swing function provides greater control and accuracy in certain lifting conditions, minimizing the shaking of a lifted object.
The intelligent floating boom offers two settings that allow the boom to move freely with the contours of the ground. In full float setting, the boom is allowed to rise and fall as required while the bucket moves across the ground — ideal for finishing work and truck loading. With the hydraulic breaker setting, the boom moves down freely under its own weight to reduce shock and vibration to extend breaker service life, and improve operator comfort.
Long arm configurations are available, depending on the model. Select models are available with super-long reach. All include a heavy-duty front design with additional reinforcement on key stress points.
This feature is beneficial for straight forward and backward travel, which is ideal in trenching applications and for transporting the machine. A single foot pedal controls both tracks.
DEVELON crawler excavators include full coverage for 36 months or 3,000 hours, whichever comes first, with parts and service support from your local authorized DEVELON dealer. Learn more here.
The optional smart around view monitor (SAVM) camera system and human detection system (HDS) on the -9 Series crawler excavators are market-leading systems that use six cameras, radar sensors and AI-powered human detection to provide a 360-degree view around the machine. They give you greater confidence when operating or positioning the machine in tight work areas or busy job sites.
SPC is implemented through two systems that work together to improve efficiency while maintaining productivity and is controlled by the engine control unit (ECU). SPC is activated by default and can be disengaged.
Variable speed control enhances fuel efficiency by reducing engine speed in the low load range to an appropriate level. It does this by detecting both the actual engine load and the operator’s activity during heavy-load operations.
Smart pump torque control reduces smoke and increases fuel efficiency by reducing unnecessary engine load through optimized control of pump torque in accordance with the engine torque.
Our factory-equipped 2D machine guidance and machine control systems are designed to make your job easier. These factory-designed smart technologies provide precise guidance and grade control, helping you work with more accuracy and efficiency. By simplifying complex tasks, the -9 Series excavators allow you to get more done in less time, improving performance and reducing costs on the job site.
MY DEVELON fleet management (telematics) is a standard feature on all -9 Series crawler excavators, making it easy to remotely monitor and maintain your machine.
This powerful equipment diagnostic tool monitors the health, location and productivity of your DEVELON equipment from a user-friendly mobile app and website.
With MY DEVELON fleet management, you can help prevent theft with a geofencing feature, avoid unauthorized use of your machine, see when maintenance is due, customize alerts to your schedule, track oil pressure, operating temperature and more, and use data to train your team for maximum productivity.
The exclusive D-ECOPOWER system on select models, improves productivity and saves fuel.
The full electric over hydraulic (FEH) system — featuring electronic pumps, main control valves (MCV) and relief control valves (RCV) — controls the precise amount of hydraulic oil required to perform a task. It results in up to 8% greater fuel efficiency and up to 20% increased engine output.
Improved feedback through the controls results in an outstanding level of operator comfort and much smoother machine management.
We prioritized operator comfort and productivity when designing the -9 Series excavator cabs. Updated features include a larger monitor and fully programmable joysticks with stick steer and thumbwheel steer. A digital key lets you unlock the cabin, start the engine and adjust the air conditioning from any distance.
Automotive-style heat and air conditioning include high-capacity vents and convenient control from the larger 12-inch Smart Touch display. Noise and vibration levels are low, while heating and air conditioning vents are repositioned to improve overall comfort and window defrosting performance.
The optional deluxe air-suspension seat in gray faux leather resists stains and delivers heating or cooling to provide a more comfortable temperature throughout the work seasons.
The seat includes two fans to cool the seat: one for the back and one for the bottom of the seat. Additional rear air nozzles move cool air to the back of the seat for improved temperature control and comfort.
The larger 12-inch high-resolution display in -9 Series model cabs offers you an easy-to-use interface to access machine information and manage various functions, including heating and cooling, selectable power modes and hydraulic flow for attachments.
Customizable to suit your personal preferences, the split screen helps improve multitasking. For enhanced efficiency, a dual monitor option is also available, enabling up to four screen splits to streamline workflow and boost operational performance.
The large cab provides an excellent viewing area through the front and side windows. When loading trucks or working overhead, the overhead window gives you great visibility above the machine. Narrow corner pillars, small window joints and a wiper mounted on the pillar — instead of on the glass surface — give you a better view of the work area.
A standard rear and sideview camera provides an additional means to view the machine’s surroundings, helping increase productivity.
A crawler excavator is a type of heavy construction equipment designed with a set of tracks instead of wheels, which enables it to move on rough and uneven terrain. The excavator tracks also provide excellent stability and traction when traveling across and working in soft soil conditions. Crawler excavator uses include trench digging, excavating, demolition and lifting.
Choosing a crawler excavator involves considering a variety of factors. These factors include project requirements (digging depth, reach and lifting capacity), excavator size, attachments, operating environment and ground conditions.
Crawler excavator prices and rental costs vary based on the local market, machine class and options. DEVELON suggests that you identify your required equipment specs and consider the available space at the job site. This will help you narrow down the options and choose an excavator that provides the performance and capabilities for you to work efficiently.
The maximum digging depth of a crawler excavator varies based on the model and size of the excavator. The digging depth depends on factors like boom length, arm length and whether there is a bucket or other attachment. DEVELON crawler excavators offer dig depths from approximately 20 to 30 feet, depending on the machine configuration. You can typically find these equipment specifications on the manufacturer's website, on the excavator model pages.
The maximum weight a crawler excavator can lift, also known as lifting capacity, varies based on the model and size of the excavator. Add-ons, such as an excavator counterweight, can increase the machine’s lifting capacity. DEVELON recommends reviewing the excavator lifting capacity chart in the Operation & Maintenance Manual before lifting any objects.
Maintenance requirements for a crawler excavator include the following: inspecting daily, checking fluids, replacing filters, greasing lubrication points, maintaining proper track tension, cleaning the cooling system and checking the electrical and hydraulic systems. An excavator maintenance checklist is a good method for tracking machine upkeep. Make excavator repairs immediately to avoid machine downtime. Use MY DEVELON fleet management (telematics) to stay on top of machine maintenance.
DEVELON crawler excavators feature hydraulic systems designed for peak performance and efficiency across various applications. These systems respond to the operator’s demand by controlling the auxiliary hydraulic pump’s flow output based on load sensing. As a result, the correct amount of flow is delivered to each function, ensuring efficient completion of the job.
A wide range of attachments is available for crawler excavators. Among the most common attachments are buckets for everyday excavating tasks. A hydraulic quick coupler is a popular option for changing attachments. Thumbs are regularly paired with buckets to grab, lift and discard materials.
Safety features for crawler excavators include a standard rear and sideview camera and optional features, such as a side view camera, LED lights and smart around view monitor (SAVM) camera system. Operating a crawler excavator safely requires proper training, adhering to safety guidelines and using the machine responsibly. Basic safety measures include conducting a thorough pre-operation inspection to identify any issues before starting work. Always wearing a seat belt. Positioning the excavator on stable and level ground. Clearing the work area of any debris and hazards that could interfere with the excavator’s movement. And finally, keeping a safe distance from the edge of the trenches.
While the -7 and -9 Series excavators share many features in common, the -9 Series models include more advanced safety and productivity features, including smart around view monitor (SAVM) camera system and human detection system, Virtual Walls (e-fencing), Lift Assist, Breaker Assist and redesigned cabs, just to name a few.
