Develon has officially launched the DX300LC-9, a 33-metric-ton excavator designed for large-scale earthmoving and utility projects. The model replaces previous dash-7 versions in the company's lineup.
Why it matters
This release updates heavy-duty construction equipment by integrating smart technology for precision grading and enhanced operator safety. These improvements aim to boost operational productivity while addressing the demand for more automated site machinery.
The DX300LC-9 operates at 33 metric tons and features a 12-inch touchscreen display for operator control. It incorporates a safety system that automatically stops the machine when personnel are detected within 6.5 feet.
The players
Develon
Develon is a global manufacturer of construction equipment, including excavators and wheel loaders, formerly known as Doosan Infracore.
The details
The excavator utilizes electro-hydraulic controls to improve fuel efficiency and includes a factory-integrated 2D system for grading and digging. Operators can monitor the machine's surroundings via a 360-degree view generated by six cameras, radar sensors, and artificial intelligence.
Timeline
September 28, 2026: The DX300LC-9 excavator was officially released.
July 1, 2025 to June 30, 2026: Nearly 15,000 new financed excavators were sold in the U.S.
Roadmap
The DX300LC-9 significantly exceeds the 10-metric-ton weight threshold for mini excavators, signaling its role in production-heavy earthmoving rather than light residential work. This transition highlights a broader industry shift toward integrating advanced AI sensors into large-scale construction fleets to enhance safety and efficiency.
Construction companies and contractors can expect improved fuel efficiency and modernized control interfaces when upgrading to this new model. The integration of remote smartphone start via the My Develon app also allows operators to manage pre-start systems with greater convenience.
The takeaway
Operators should utilize the new 360-degree camera and radar sensors to standardize safety protocols on job sites. Ensuring staff remain outside the 6.5-foot automated stop zone is critical for leveraging the machine's safety features.
