Steel Mill Loader
Liebherr has developed a specialist crawler loader in its
fully hydrostatic range, specifically designed and built
for slag handling in steel mill applications. The Steel Mill
Loaders incorporate numerous safety and operating
features for the efficient handling and loading of hot slag
in extreme temperatures.
The LR 624 STM Litronic and LR 634 STM Litronic have
an operating weight of around 19/23 tonnes, with a tip-
ping load in the region of 12/14 tonnes. The engine is a
Liebherr made D934 (emission regulations according to
97/68/EC, 2004/26/EC, Stage IIIA and EPA/CARB Tier 3),
which develops 105/129 kW at 1800 rpm.
The special wide heat-resistant bucket on this machine
has a capacity of 1,5/2 m³ and is constructed from Har-
dox 400 for optimum wear resistance. The somewhat
unusually arduous application for which this machine is
designed requires highly specialised features – not only
to withstand direct heat radiation but also high tempera-
tures from heat transfer by direct contact through both
the bucket and the undercarriage. Additionally, the safety
and comfort of the operator is also a priority. Liebherr
has equipped the LR 624 STM Litronic and LR 634 STM
Litronic with a complete package for heat and abrasive
dust resistance.
