Remote controlled mini-format demolishing machine with unique kinematics

Published 7/3 at 17:10

At bauma 2019 German manufacturer TML will be showing its new Unidachs 110 demolishing machine, which has been developed especially as a manipulator for a diverse range of attachments.

This is an unusually small and compact machine designed for working in very tight spaces and where working space and height are restricted, with a radio remote control that allows the operator to work at a safe distance.

The new Unidachs 110 has a compact design and a unique 360° endlessly rotatable boom, high manoeuvrability and hydraulic drive. The width of the undercarriage is only 1,315 mm and the height is 1,635mm. This allows access to working areas in tunnels or buildings that are not easily accessible for other machines and due to the remote operation the operator is always at a safe distance. When compared with mini excavators with an articulated arm, it has a further degree of motion. The 360° boom rotation, combined with the double articulated cantilever boom, offers a very high level of flexibility for attachments such as rotary drum cutters, hydraulic hammers, ripper buckets, ripper hooks, shears, pulverisers or buckets.

The machine is designed for applications in tunnels, mines, the demolition or dismantling of buildings, as well as for de-bricking rotary cement kilns. Despite its compact size, depending on the attachment, and in combination with the kinematics of the boom, a working radius of up to 5,000mm can be reached. Every point of a cross gallery profile from which material needs to be removed can be more or less reached without repositioning. The machines are available with a choice of diesel-hydraulic or electro-hydraulic drives. Diesel engines have either 26kW (EU Stage 3a) or 18.5kW (EPA Tier 4), with the electro-hydraulic unit being 25kW.

Volker Bongardt, international sales manager of TML Technik GmbH, sees great advantages for his customers: "The machine users appreciate the combination of the cantilever boom and the boom rotation, especially the fact that they are able to work from a single position and at the same time reach areas that was not possible in the past. 

Demolition robots and mini excavators with articulated booms do not offer this kind of kinematics. Our customers are now able to profit through the multi functionality known from other machines that we build.”

 

Applications

The new Unidachs 110 is suitable, among other things, for applications in mining and tunnelling for penetrating cross galleries, profiling tunnel cross sections, scaling with a hammer, a rotary drum cutter and clearing with a choice of buckets. In addition, it can be used as a carrier machine for drilling rigs, setting tools for bows and anchors. Thanks to its compact design and manoeuvrability, the Unidachs 110 can also work in hard to reach areas during demolition work. This makes it particularly suited to dismantling or demolishing in hazardous areas, where the remote control is of use. It offers maximum safety for the employees on site and minimises potential dangers arising, for example, from collapsing walls or falling material. In addition, optional cameras can be installed on the machine. In the cement industry for example, when milling or reworking the inner surfaces of the rotary kilns, the 360° rotatable boom reaches every point of its working area without repositioning, and provides the necessary force to break the often heavily sintered refractory lining.

TML Technik will exhibit in Hall C5, booth C5.324 at bauma 2019.
