Develon DA30-7 Articulated Dump Truck

Built to Perform in Challenging Terrain

The Develon DA30-7 articulated dump truck is engineered to maximize productivity in demanding off-road applications, moving more material efficiently across rough terrain and challenging jobsites. Its innovative chassis design features a front-mounted turning ring, sloped rear frame, and free-swinging rear tandem bogie to maintain continuous six-wheel ground contact for superior traction and stability. A limited-slip differential automatically directs torque to the wheels with the best grip, delivering confident performance in difficult conditions, while the Auto Hold brake system reduces operator fatigue and minimizes transmission wear by automatically holding the truck in position when stopped.

Smooth Ride and Easy Transport

The DA30-7 is designed to provide exceptional ride quality and operator confidence. A hydro-gas, self-leveling front suspension system absorbs shocks and maintains stability over uneven terrain, delivering a smoother ride whether the truck is fully loaded or empty. Operators can also manually adjust suspension pressure to suit changing jobsite conditions. With an overall width of less than 10 feet, the DA30-7 is easy to transport between jobsites, reducing logistics challenges and increasing fleet flexibility.

Simplified Maintenance for Maximum Uptime

Routine maintenance is faster and more convenient thanks to ground-level access to fuel and diesel exhaust fluid (DEF) fill points, an easily accessible power module, and a centralized service panel. Common oil is shared between the wheel hubs, tandem rear bogie, and limited-slip differential to simplify servicing, while a larger 20-liter automatic grease system extends lubrication intervals and reduces maintenance time. Standard MY DEVELON fleet management allows owners to remotely monitor machine health, productivity, location, and maintenance information through lifetime cellular connectivity.

Premium Operator Comfort and Control

The redesigned automotive-style cab creates a comfortable and intuitive operating environment that helps operators stay productive throughout long workdays. Fully automatic climate control, a heated air-suspension seat, low interior noise levels, and responsive steering reduce fatigue while improving overall comfort. A high-performance vehicle control unit with a faster processor powers the intuitive 12-inch display, providing clear access to machine information, operating data, warnings, and multiple camera views. Standard electrically adjustable mirrors and convenient USB charging ports further enhance operator convenience.

Efficient Tier 4 Performance

The DA30-7 meets Tier 4 emissions requirements using a high-pressure common-rail (HPCR) fuel system combined with cooled exhaust gas recirculation (CEGR), a diesel oxidation catalyst (DOC), and selective catalytic reduction (SCR). This advanced emissions technology delivers dependable power, improved fuel efficiency, and environmentally compliant performance for demanding hauling applications.
