Using the DEVELON Fleet Management, you can monitor your equipment and check on machine status from a user-friendly mobile app and website.
A variety of fuel efficiency technologies optimize machine performance while reducing fuel consumption, including the exclusive D-ECOPOWER system, Smart Power Control (SPC) and Electronic Power Optimizing System (EPOS). The dependable DEVELON diesel engine delivers more power output with reduced fuel consumption.
The optional 360-degree all-around view monitoring (AVM) camera system gives you greater confidence when operating the machine in tight work areas. Simplified Maintenance. Proven Durability.
SIMPLIFIED MAINTENANCE. PROVEN DURABILITY.
Enjoy reduced maintenance costs and extended machine life with the durable X-Chassis undercarriage, strengthened boom and arm assembly, and extended greasing intervals. A new Y-shaped seal at the end of the excavator arm provides better sealing to the bucket connection, and improved hydraulic line routing also helps protect your investment.
To make maintenance convenient, access panels are easy to find and open from the top, bottom and sides of the excavator. The centralized boom and arm grease points are grouped for easy maintenance.
