Description
DX300LC-9 | Develon
Smarter Solutions for Safer Job Sites
The DEVELON DX300LC-9 crawler excavator enhances jobsite safety with Virtual Walls (e-fencing) that limit machine movement within operator-defined boundaries. Optional Smart Around View Monitor (SAVM) and Human Detection System (HDS) technologies use six cameras, radar sensors, and AI for 360-degree visibility. Collision Avoidance Assist automatically slows the machine when a person is detected within 13 feet and stops it completely within 6.5 feet.
Advanced Technology for Greater Productivity
The DEVELON DX300LC-9 boosts productivity with advanced technology, including an onboard weighing system for optimized truck loading, Lift Assist and optional Advanced Lift Assist for safer lifting, and Breaker Assist to reduce wear and improve operator comfort. Factory-equipped 2D machine guidance and control systems enhance digging accuracy and efficiency.
Redesigned Cab for Operator Comfort
The DEVELON DX300LC-9 features a redesigned cab with customizable joystick controls, stick steer and thumbwheel steer options, and a 12-inch high-resolution display for easy machine management. Automotive-style heating and air conditioning, improved defrosting, and convenient touchscreen controls enhance operator comfort. The available digital key allows operators to unlock the cab, start the engine, and adjust climate settings through the MY DEVELON app.
Built to Maximize Uptime
The DEVELON DX300LC-9 maximizes uptime with four selectable power modes and D-ECOPOWER™ technology for improved fuel efficiency and productivity. Ground-level filter access simplifies routine maintenance, while advanced Prognostics and Health Management (PHM) monitors critical components to anticipate service needs, reduce downtime, and lower maintenance costs.
