Liebherr LTR 1220

Launched with an eye towards enhancing versatility and reducing logistical costs in heavy crane operations, the Liebherr LTR 1220 is a substantial player in the heavy lifting industry. It features a 60-metre telescopic boom identical to that on the LTM 1220-5.2 all-terrain crane, which is pivotal for projects requiring high reach and strong load capacities. The crane’s functionality is expandable with a 12.2 to 22.2-metre bi-fold swing-away jib, and further with two 7-metre lattice jib extensions, allowing for flexible adaptations to various project requirements.

Innovative Use as Derrick Ballast A significant development in November 2014 revealed that the LTR 1220 could be used as a derrick ballast for the Liebherr LR 1600/2 crawler crane. This adaptation was primarily aimed at the construction of tall wind power systems, showcasing a novel approach to managing the heavy counterweights typically necessary for such tasks. By utilizing the LTR 1220 in conjunction with just 70 tonnes of counterweight, the system greatly reduces the usual requirement of 350 tonnes. This innovation not only cuts down on transportation costs of heavy counterweights but also streamlines the setup process for long boom configurations.

Configuration and Adaptability During a demonstration at the Liebherr-Werk Ehingen factory, the LTR 1220 was shown configured in an SL10DFB setup with a 153-metre main boom and a 12-metre fixed jib. This configuration reduces the need for conventional counterweight systems and is adaptable for both new and existing boom systems (SL10, SL13, and SL4), proving the crane’s versatility in handling various industrial requirements.

Economic and Operational Benefits The strategic use of the LTR 1220 as derrick ballast exemplifies a forward-thinking approach to crane design and usage, aligning with the industry’s needs for more economically and logistically feasible lifting solutions. By minimizing the need for extensive counterweights, projects can achieve significant savings and efficiencies, particularly beneficial in the erection of large-scale wind turbines and other tall structures.

Conclusion The Liebherr LTR 1220 not only stands out for its high capacity and extendable reach but also for its innovative role in reducing operational costs in heavy lifting operations. Its debut and subsequent developments highlight Liebherr’s commitment to advancing crane technology and meeting the complex demands of modern construction environments. This crane remains a pivotal asset for challenging projects, enhancing efficiency and adaptability across varied applications.

Milestones

Albert Regel gets the first LTR1220 in Germany – The first unit of Liebherr LTR1220 in Germany was delivered to a German local crane and heavy transport contractor, Albert Regel GmbH based in Baunatal near Kassel, Germany. The 220-tonne telescopic crawler crane displayed its capabilities during the construction of a building in Villingen-Schwenningen and proved an immediate hit with its functionality and flexibility for handling prefabricated concrete components. With its chassis excel with off-road capability and superb manoeuvrability, the telescopic crawler crane is ideal for the site. Additionally, the crane can move with lifting a full load. At the same time, the Liebherr telescopic crawler crane feature short setup time, well-designed transportation and high variability of the boom systems.

Transportation Partners & Logistics gets the first LTR1220 in the USA – Heavy lift and haulage company Transportation Partners & Logistics LLC (TP&L) has taken delivery of the first LTR1220 telescopic crawler crane in America during August 2013. The crane went straight to work, unloading wind turbine mast section. The company mentioned that the 220-tonne telescopic crawler is an ideal crane for the job due to its ability to drive on narrow wind farm roads with a track width of just 4.5 metres, which extend to 7.25 metres for lifting operations.

Guindastes Tatuape gets the first LTR1220 in Brazil – Brazilian heavy lift and haulage company Guindastes Tatuape has taken the delivery of the first LTR1220 in Brazil. They have decided to purchase the Liebherr LTR1220 after having a good working experience with the smaller capacity LTR1100.
