New DX235RTF-7 Tunnelling Excavator from DEVELON Revolutionizes Underground Construction

Introduction to the DX235RTF-7 Tunnelling Excavator

DEVELON, formerly known as Doosan Construction Equipment, proudly introduces the DX235RTF-7 Tunnelling Excavator, an innovative addition to its line-up of Special Application machines. This cutting-edge excavator is engineered to excel in challenging underground environments, providing exceptional power and precision for tunnelling projects.

Advanced Features and Robust Design

The DX235RTF-7 Tunnelling Excavator builds on the proven design of the DX235LCR-7 reduced radius crawler excavator. Powered by a DL06V Stage V engine, it delivers 141 kW (189 HP), ensuring robust performance. The machine’s compact design and minimum swing radius are ideal for navigating tight spaces, a crucial feature in tunnelling applications.

Enhanced Performance with Tunnelling Front

The standout feature of the DX235RTF-7 is its heavy-duty Tunnelling Front, which includes a newly designed arm and boom with special kinematics and a tilting function. This design allows for a 45°/45° tilt in two directions, controlled via a pedal in the operator’s cab, optimizing horizontal reach and precision.

Jan Breburda, Special Applications Product Manager for Develon Europe, states, “The new DX235RTF-7 tunnelling machine is designed for superior performance in challenging underground environments. Complementing the safety and comfort of its operation, the advanced hydraulics and robust construction of the DX235RTF-7 ensure optimal power and durability, while its compact design allows for easy navigation in tight spaces.”

Specifications and Protective Features

The DX235RTF-7 boasts a total operating weight of 25,689 kg and a maximum reach of 9260 mm. Its design prioritizes operation in narrow areas without the need for extensive swing movement. Protective equipment, including a level 2 FOG system, heavy-duty covers, and hydraulic piping protection, ensures safe operation in confined spaces.

Additional features include six LED work lights, AVM cameras, PERO rotating piping, centralized greasing points, and an optional dozer blade. The excavator’s specifications are designed for easy transportation and maneuverability in areas with limited access.
