The Liebherr standard mobile crane LTM 1055-3.1 is de-
signed for high performance. The in-house fabricated and
field-proven components such as Diesel engine, winch,
slewing gear and slewing ring are especially laid out for the
application on a mobile crane.
High load capacities, quick working cycles and sensitive op-
erating motions permit perfect load handling. The telescopic
boom of inherent stability is extended by the convenient sin-
gle-ram telescoping system Telematik to the desired boom
length. A multitude of telescoping variants permit optimal
utilization of the telescopic boom’s capacity.
Thanks to the high output of the Diesel engine and the pump
as well as to the regulated load-sensing control, four working
motions can be performed independently of one another.
The LTM 1055-3.1 offers a variable supporting basis and is
leveled automatically. The „key-hole method“ permits con-
venient control of ballasting the crane from the crane cab.
4,7 t or 7 t partial ballast and 12 t maximum ballast allow vari-
able and economic performance of the crane interventions.
Even at a failure of the Diesel engine or of the hydraulic
pump, the interrupted crane operation can be finalized by
means of the hydraulic emergency set and the crane can be
derigged into driving position.
