The standard mobile crane type LTM 1055-3.1
with optional equipment for special requirements
High load capacities, an extraordinary mobility, comprehensive convenience and safety equipment as well as a practice-oriented transport concept for crane accessories and
optional equipment characterize the standard mobile crane
LTM 1055-3.1 from Liebherr, modied for the army.
The 3-axle, 55-tonner, positioned on outriggers or free on
wheels, offers outstanding load capacities. The 32,5 m long,
torsion-resistant telescopic boom lifts loads to 32 m height
under hook at radii of up to 28 m. Supporting basis and
counterweights are variable for a comprehensive application spectrum. High working speeds even permit the quick
handling of loads. The safe load indicator LICCON guarantees fully automatic control of the crane performance in all
operative ranges.
Outstanding
performance
The LTM 1055-3.1 is compact and maneuverable, its operative weight is 36 tons with equal axle load distribution of 12 t
per axle and the control of relocating and setting on outriggers is even possible from the crane cab. The modern LIASDRIVE provides a crane-specic, intelligent travel strategy
for a smooth driving quality at economic fuel consumption.
High mobility and
efficiency
Driver’s cab and crane operator’s cab are modern, ergonomically designed working places. The standard cabs can
be interchanged with armoured versions within a few hours
if required. And instead of the standard tyre equipment, special tyres with emergency running capabilities provide for an
increased mobility.
Comprehensive
equipment for convenience and safety
Containers are provided for the transport of the crane accessories and the optional equipment. All accessories and
the optional equipment, required for everyday operation, are
stowed in containers, loaded on lorries by the crane and are
available for crane operation if required.

The Liebherr standard mobile crane LTM 1055-3.1 is designed for high performance. The in-house fabricated and
eld-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 operating motions permit perfect load handling. The telescopic
boom of inherent stability is extended by the convenient single-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 convenient control of ballasting the crane from the crane cab.
4,7 t or 7 t partial ballast and 12 t maximum ballast allow variable 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 nalized by
means of the hydraulic emergency set and the crane can be
derigged into driving position.
