Having created a “scaling kit” to convert
the model 852TSL underground utility
vehicle to a scaler last year,
Hermann Paus Maschinenfabrik has now
launched a scaler series. The German
niche product manufacturer says its TSL-S
scaler series offers the latest, most flexible
and highest performance solution for securing
hanging walls in underground mining
and tunneling. The Paus TSL-S scalers
combine maneuverability and flexibility
through small machine dimensions, hydrostatic
four-wheel drive with power-limiting
control unit, the articulated joint design
and a telescopic boom swiveling by +/- 45°.
These machines provide a “quick task
force” at the face, Paus says. After having
finished work in one area, the machine can
move to the next site quickly: there are no
special transportation requirements.
Another advantage of the new units is
their ability to apply impact force to the
rock in a precise manner. The use of a
comparatively small hammer (the 200-kg
NPK GH 203) protects the hanging roof
from further damage caused by over-penetration.
The TSL-S ensures loose rock fracture
on the spot without causing further
unwanted spalling. By using the hydraulic
feed of the telescopic boom together with
the impact force of the hammer, the breaking
action can be restricted to the minimum
required for effective scaling. These
features ensure that the TSL-S7 (7.8-m
reach) and new TSL-S12 (11.5-m reach)
are able to achieve efficient strata control
and to cope with hard, solid rock as well as
with brittle, soft and fragmented rock.
