Liebherr LTC 1050–3.1 Crane Now Available With Telematik or Rope Boom

LTC 1050-3.1 available with either Telematik or rope boom:
A new alternative for crane contractors who chiefly use the compact crane inside buildings.The customer has the choice – power, and length, or familiarity and speed. Liebherr has developed another option for its successful LTC 1050-3.1 compact crane – in the future crane contractors will have the choice between the existing 36-meter telescopic boom with the Telematik fast cycle telescoping system and a new 31meter boom featuring rope extension technology. The first machines with the new telescopic boom will be delivered in the second half of 2021.

The development of the Telematik single-cylinder fast cycle telescoping system at the end of the 90s not only won Liebherr a series of innovation awards but also revolutionized the crane market.

Telematik provided the basis for the development of multi-section and therefore ever longer telescopic booms with increased performance. The system operates using just one hydraulic cylinder and an internal locking system for the individual telescoping sections. The telescoping sections are extended easily and automatically to the required lengths using the hydraulic cylinder and are then pinned.

Lightweight single-cylinder extension system: powerful and long

This lightweight single-cylinder extension system delivers high lifting capacities with long
booms and large radii. But even with the booms not fully extended, Telematik delivers
higher lifting capacities as the individual telescoping sections can be extended in any
sequence and independently of each other.
As a result of its many benefits, Liebherr used Telematik on the LTC 1045-3.1, which was
launched in 2010, and its successor, the LTC 1050-3.1, which replaced it from 2015.

Boom with rope extension mechanism – familiar and fast

Crane contractors who chiefly use the Liebherr compact crane inside buildings and mostly do not need the full length of the 36-meter telescopic boom to see also benefits of a boom with rope pull technology – the telescoping process is faster and many operators of mobile cranes in the lifting capacity class, up to 50 tonnes are familiar with rope pull technology.

Liebherr uses a hydro-mechanical telescoping system on LTM mobile cranes whose telescopic boom consists of the pivot section and a maximum of three telescoping sections.
The integral rope pull technology enables the telescopic boom to be extended to the required length particularly easily and quickly.

After in-depth discussions with customers, Liebherr decided to develop a boom with a rope extension mechanism as an alternative for the LTC 1050-3.1. This is 31 meters long and consists of a pivot section and 4 telescoping sections – one less than the Telematik boom.
The telescoping sections are extended and retracted using a dual-action 2-stage hydraulic
cylinder. Stage 1 extends telescoping section 1. Stage 2 extends telescoping sections 2 to 4 synchronously using a 2-way pulley block. The new boom also delivers high telescoping lifting capacities, an important feature for use inside buildings.
