Develon has launched the DX235RTF-7 tunnelling excavator, a brand new extension to the corporate’s lineup of particular utility machines.
The DX235RTF-7 is predicated on Develon’s well-established DX235LCR-7 lowered radius crawler excavator and is powered by a DL06V Stage V engine, offering 141 kW (189 HP) of energy.
The DX235RTF-7 utilises the profitable compact design and minimal swing radius of the DX235LCR-7, however the important thing a part of the machine is the heavy-duty tunnelling entrance, providing a brand new arm and increase design with particular kinematics and a tilting operate.
Jan Breburda, particular purposes product supervisor for Develon Europe, commented: “The brand new DX235RTF-7 tunnelling machine is designed for superior efficiency in difficult underground environments. Complementing the protection and luxury of its operation, the superior hydraulics and sturdy building of the DX235RTF-7 guarantee optimum energy and sturdiness, whereas its compact design permits for simple navigation in tight areas.”
The DX235RTF-7 has a complete working weight of 25,689 kg and affords a most attain of 9260 mm. The kinematics of the tunnelling entrance on the DX235RTF-7 excavator are designed to prioritise horizontal attain and precision over vertical motion. The particular kinematics are based mostly round a increase tilting operate, offering a forty five°/45° tilt in two instructions, the motion of which will be operated through a pedal within the operator’s cab.
The increase and arm configuration is particularly designed for operation in slim areas, with ranges of motion barely restricted in comparison with the usual entrance on the DX235LCR-7. The DX235RTF-7 is particularly suited to work in restricted environments, with out utilizing the swing motion in slim areas. This permits the DX235RTF-7 to work effectively in slim tunnels with the flexibility to achieve the tunnel face and partitions, whereas sustaining a low profile to navigate tight areas.
For work in confined areas, the DX235RTF-7 options protecting tools to safeguard in opposition to falling particles or contact of the arm with the tunnel ceiling and partitions. In consequence, the DX235RTF-7 has a degree 2 FOG system mixed with extra heavy responsibility covers and hydraulic piping safety.
The safety additionally contains covers over hydraulic hoses and arm work lights, in addition to enclosing the bucket cylinder and hyperlinks in a devoted protecting compartment and hiding the arm cylinder beneath the arm.
In comparison with the usual DX235LCR-7 mannequin, the DX235RTF-7 has six LED work lights, 4 on the entrance and two on the again, in addition to AVM cameras as normal. Different options embrace PERO rotating piping, centralized greasing factors and a dozer blade as an choice. The specs additionally embrace a 6.4 tonne counterweight and 600 mm vast triple grouser observe footwear.
Tunnelling purposes typically require the transportation of the machine to areas with restricted entry, so the DX235RTF-7 is designed to be easy to raise and manoeuvre into place.
