Machines for mining and tunnelling: 360° continuously rotary, telescopic boom with an additional degree of motionng:
At the BAUMA 2019 TML will be showing one of its mining machines, the UNIDACHS 740 „Scaler“. The machine has a high specifation. „Mining Package“ which is a special concept for the mining and tunnelling applications. The UNIDACHS“ 360° rotary, telescopic boom offers a high range of flexibility as well as a long reach while the height of the machine is relatively low, allowing quite large sections to be profiled in a very safe manner.
The „Mining Package“ adapts the UNIDACHS 740 „Scaler“ to the extreme conditions underground: In addition to the unique kinematics of the telescopic boom, the package offers comprehensive protection for the machine operators.
The operators cabin has a Falling Objects Protection System (FOPS) installed on the roof and on the front screen which is made of armoured safety glass; the cabin is tiltable so that the operator has an optimal upward view.
Above that the machine itself is protected for the typical underground mining and tunneling environment: i.e. TML hides the hydraulic hoses away in a guide system inside the telescopic boom.
This ensures that the hoses are protected against any damage, in the case that loose rocks or debris falls onto the boom while working. This measure not only increases the availability of the machine, it also reduces the risk of hydraulic oil leakages to almost zero. A robust steel housing closes off the inside of the machine to prevent the ingress of any foreign objects.
In addition there are particularly high-intensity xenon working lights, bumper protection rails for the superstructure, armoured glass in the front area of the cabin roof, protective covers for the boom guide rollers, deflector plates in the front area of the main boom, dirt deflectors brushes between the main and telescopic booms, as well as a camera system that allows you to see to the rear and to the side areas.
Volker Bongardt, International Sales Manager at TML Technik GmbH, knows the rough conditions under which his machines have to work: „Our design is very cost-conscious, but there are two aspects where no costs are spared: the safety of the operators and the availability of our machine. All structures of the machine are made of steel and not of plastic.“
In mining and tunnelling, the UNIDACHS 740 „Scaler“ is suitable, among other things, for scaling with a breaker, a ripper or a rotary drum cutter, as well as different types of buckets for clearing of debris, profiling of tunnel sections, or breaking through cross galleries.
In addition, it can be used as a carrier machine for i.e. drilling rigs, setting tools for bows and anchors. TML Technik is also setting a new benchmark with the combination of the 360-degree rotating boom with swash-spray nozzles for concrete.
The technology in detail:
TML supplies the machines with either diesel with 180 KW or with an electro motor drive with 132 KW which among other things reduces the demands for ventilation extremely.
The 360° rotary telescopic boom covers a working angle range of +33° and -74°. With a telescopic stroke of 4.000 mm and a 2,5 m long attachment a total reach of up to 14 m is possible.
The „Scaler“ achieves a boom rotation torque of 32 kN m and telescopic push and pull forces of 150 kN.
