A new 120-tonner fills the gap between the 100 and 200-tonne classes at Servet Coşkun Vinç
Turkish rental company Servet Coşkun Vinç has taken a new Liebherr LTM 1120-4.1, choosing the four-axle 120-tonner for tower crane erection, steelwork and refinery jobs where access is tight but the boom still has to be long.
Four axles, 66 metres of boom
Servet Coşkun Vinç has put a new Liebherr LTM 1120-4.1 into its Istanbul fleet, slotting a four-axle machine in between the 100 and 200-tonne cranes it already runs. The attraction is the combination the class is known for: 120 tonnes of capacity on a compact carrier, and nine tonnes still available on the fully extended 66-metre telescopic boom.
“We spent a long time looking for a mobile crane with four axles and finally decided on the 120 tonne Liebherr unit since it is not only the most powerful crane in its class, but also has the longest boom. Apart from the high quality of their products, we have had very good experiences with Liebherr in Turkey for many years and are extremely satisfied with their level of service.”

Support base and driveline
The crane is specified with VarioBase, which allows the outriggers to be extended to different lengths and releases additional capacity in particular over the sliding beams — the configuration that matters most when the machine is boxed in on an industrial site. Hillstart Aid handles pull-away on gradients without rollback.
On the driveline side, ECOdrive lowers engine speed on the road for a quieter, more comfortable ride and quicker gearshifts off-road, while making better use of the Liebherr diesel’s torque to hold down fuel burn. ECOmode does the equivalent job in crane operation: the operator sets the required working speed on the control lever and the LICCON control system works out the engine rpm needed to deliver it, cutting both fuel consumption and noise.
Where it will work
Planned duties include erecting tower cranes, steel construction, refinery work and lifting inside buildings. Coşkun points to the capacity available on the long boom, the strong rope pull and the small support base as the decisive features for that mix, adding that the crane’s compact dimensions and turning circle suit narrow streets and confined working areas.
The company has rented out industrial machinery for around 40 years and employs 55 people. Its fleet covers cranes, access platforms and forklifts, with 25 cranes of various types in total; of the five all-terrains, three are Liebherr. An LTM 1450-8.1 and an LTM 1230-5.1 were due to follow in early 2024.
