Remotely controlled machine with 360° rotary telescopic arm for working in confined spaces
17.10.2022For the first time TML will present at bauma the new, fully remotely controlled mobile machine UNIDACHS 430RK.

Thanks to the special kinematics of its 360° endlessly rotating telescopic boom and its compact dimensions, the machine makes it possible to work in confined spaces or in areas with difficult access. The operator works at a safe distance using the radio remote control. TML developed the new UNIDACHS 430RK for job sites where the available space, surrounding structures or dangerous conditions make work difficult. The "RK" in the product name stands for "Remote" and "Knickgelenk" (articulated joint): all the machine's functions are remotely controlled, the additional cradle mount for the telescopic boom makes it possible to work over a particularly large working area even in a confined space.
This new degree of freedom makes the UNIDACHS 430RK combined with the proven, 360° rotary telescopic arm into a machine of universal application for the removal or application of material, or for machining surfaces. The attachments – for example pneumatic or hydraulic hammers, ripper tips, rotary drum cutters as well as various types of excavator bucket – can be moved in up to five axes simultaneously. They can be used, for instance, in the roof and side wall areas, underneath the machine or in confined spaces, at almost any angle – and that from only one location.
The boom on the UNIDACHS 110 has a reach of up to 5000 mm. As such the UNIDACHS can reach the complete profile of a service passage, adit or tunnel

Typical applications are profiling tunnel cross-sections, the excavation of caverns and galleries, the precise linear scaling of roofs and walls in mines and tunnels. The telescopic arm can also be fitted, for instance, with spray nozzles for liquid concrete as well as drilling attachments and tools for setting arches and anchors. Thorsten Bolender, Sales Manager Tunnel & Mining at TML, emphasises: "With the compact design and its unique kinematics, the new UNIDACHS 430RK makes it possible to work safely in places that standard hydraulic excavators cannot reach. The telescopic arm covers a vertical slewing range of +45° to -108°; with a telescopic stroke of 3000 mm the attachment reaches heights of more than 10 m. At the same time, the telescopic arm provides a torque of 14.8 kNm as well as a maximum breakout force of 73 kN."

The compact UNIDACHS 110
At bauma 2022, TML will exhibit the particularly compact machine UNIDACHS 110 also with the 360° endlessly rotating boom arm. Application areas and configuration variants are similar to those of the UNIDACHS 430RK, however, the machine is significantly more compact.
With its small dimensions – the chassis is only 1315 mm wide, 1644 mm high – it is suitable for work in particularly confined spaces. Nevertheless, the machine has a large working area: the boom has a reach of up to 5000 mm, depending on the length of the attachment. As such the UNIDACHS can reach the complete profile of a service passage, adit or tunnel from one location and therefore all areas in which material is to be removed, worked or applied. Thorsten Bolender sees not only technical but also commercial advantages: "The UNIDACHS 110 is the only machine for mining and tunnelling available on the market that is extremely compact and at the same time offers all the advantages of the rotating boom arm. These features open up completely new optimisation potential in mining and tunnelling for our customers: they can now work cost-effectively even in extremely confined spaces."
