DX400LC-9 | Develon

Smarter Solutions for Safer Job Sites

The Develon DX400LC-9 brings advanced safety technology to the 40-ton excavator class, helping operators work more confidently on demanding jobsites. Virtual Walls (e-fencing) allow you to establish machine movement limits, improving safety by preventing operation beyond preset boundaries. Optional Smart Around View Monitor (SAVM) and Human Detection System (HDS) technologies combine six cameras, radar sensors, and artificial intelligence to provide a complete 360-degree view around the machine. The integrated E-Stop system automatically slows the excavator when a person is detected within 13 feet and brings it to a complete stop if someone enters within 6.5 feet.

Advanced Technology for Greater Productivity

The DX400LC-9 is equipped with intelligent technologies that help maximize efficiency and jobsite performance. An onboard weighing system enables operators to accurately monitor material volumes and optimize truck loading, while Lift Assist and Advanced Lift Assist provide real-time lifting capacity information and alert operators to potential tipping hazards. Breaker Assist helps prevent blank firing, reducing attachment wear while improving operator comfort and extending machine life. Factory-installed 2D machine guidance and machine control systems provide accurate grade guidance and excavation assistance, helping improve productivity while minimizing rework.

Redesigned Cab for Operator Comfort

The redesigned operator station delivers exceptional comfort, visibility, and control throughout the workday. A customizable joystick allows operators to personalize controls, including stick steer and thumbwheel steer functions, while the large 12-inch high-resolution touchscreen display provides quick access to machine settings and operating information. Automotive-style heating and air conditioning, high-capacity air vents, and improved windshield defrosting create a comfortable working environment in all weather conditions.

Built to Maximize Uptime

The DX400LC-9 is engineered to reduce operating costs while maximizing machine availability. Four selectable power modes allow operators to optimize fuel efficiency and performance for changing jobsite conditions, while the exclusive D-ECOPOWER™ hydraulic system improves productivity and reduces fuel consumption. Ground-level access to routine service points simplifies daily maintenance, and Advanced Prognostics and Health Management (PHM) technology continuously monitors critical components such as hydraulic oil, engine oil, and main pumps to help predict maintenance needs, minimize downtime, and lower long-term service costs.
