Description
Develon DX140LC-7K
Powerful Performance in Tight Work Areas
The Develon DX140LC-7K is built to deliver exceptional performance in confined jobsites where maneuverability is essential. Ideal for work near bridges, along roadways, and in congested urban environments, this crawler excavator features four selectable power modes, a standard arm configuration, and an available dozer blade for added stability and efficient backfilling. Powerful hydraulics provide impressive digging and lifting performance, while the standard one-touch power boost temporarily increases hydraulic force for demanding excavation conditions. Boom cylinder holding valves, mounted on the rear of the hydraulic cylinders, enhance safety during lifting and digging while helping reduce the risk of machine damage.
Operator Comfort and Outstanding Visibility
Designed to maximize operator comfort throughout long workdays, the DX140LC-7K features a quiet cab with sound-isolating seals, automotive-style heating and air conditioning, and a standard heated air-suspension seat. An available heated and cooled air-suspension seat provides even greater comfort in extreme weather conditions. A large tablet-style display offers intuitive machine controls and easy access to operating information, while low-effort joystick controls reduce fatigue when operating hydraulic attachments. Standard rearview cameras, excellent right-side visibility, and an available 360-degree Around View Monitor (AVM) camera system help improve operator awareness and jobsite safety.
Advanced Machine Functionality
The DX140LC-7K incorporates advanced technologies that improve productivity and versatility across a wide range of applications. An available boom float function allows the boom to follow ground contours for more efficient finish grading, while the automatic downshift feature increases traction and drawbar pull during uphill travel. A hydraulic quick coupler enables fast attachment changes without leaving the cab, and an electric two-way foot pedal simplifies hydraulic attachment operation, allowing operators to complete more work with greater efficiency.
Simplified Maintenance and Fuel Efficiency
Routine maintenance is fast and convenient thanks to ground-level access to the diesel exhaust fluid (DEF) tank and fuel refill point, along with safe access to the upper structure through strategically placed handrails and anti-slip steps. The exclusive Smart Power Control (SPC) and Mechatronics Design systems automatically optimize hydraulic and engine performance to improve fuel efficiency without sacrificing productivity. Standard auto idle and auto shutdown functions further reduce fuel consumption, helping lower operating costs while ensuring compliance with current North American emissions standards.
