The last LR 1600/2 Leaves Liebherr’s Ehingen Plant

A daily job for the LR 1600/2: installation of wind power components.

The end of an era after 220 models built – production of one of Liebherr’s most successful crawler cranes is being discontinued. The last LR 1600/2, which was primarily designed and used for wind power jobs, will be delivered at the end of October. Its successor is the LR 1700-1.0, which Liebherr launched in June 2021 and which has already become very popular all over the world as the new standard in the crawler crane segment for wind power.

The 600t LR 1600/2 crawler crane is being removed from the Liebherr crawler crane portfolio. 223 of them have been built and delivered to customers over a period of almost 13 years. Its successor has already been launched in the form of the LR 1700-1.0.

The LR 1600/2 was originally designed as a crane for wind power and the first one was delivered in summer 2008. In addition to the standard version, a version with narrow crawler track, known as the LR 1600/2-W, was also marketed successfully over a period of ten years. The main feature of this version was the fact that it could travel along narrow crawlers in wind farms considerably more easily than the standard version. The narrow track version accounted for around one-quarter of all these cranes in worldwide use.

Initially, the LR 1600/2 was delivered in its SL4DFB configuration, designed for wind turbines with a hub height of 130m to 135m. In this configuration, the crane had a main boom of 138m and a fixed jib of 12m. This was the benchmark for turbines with a hub height of 135m. Over the next few years, however, the size of wind turbines increased dramatically up to hub heights of 150m or more. This altered the requirements for the crane which the designers at Liebherr followed closely. The lifting capacities and hoisting heights of the boom systems were continuously modified with the SL10 and SL13 versions, which both became established on the market. These booms enabled the crane to handle wind turbines with hub heights of 150m.

However, the LR 1600/2 was not just used for wind power, it was also used in industry and for infrastructure projects shortly after the first one was delivered to its customer. Often equipped with a ballast wagon or suspended ballast, the 600t crane impressed users with its lifting capacity. Over the years, Liebherr unveiled more innovations for its crawler crane portfolio, such as the B2 guide and VarioTray for suspended ballast, which eliminates the complicated stacking and unstacking of ballast slabs by simply disconnecting a whole ballast pallet.

The final LR 1600/2 will be delivered to van Adrighem based in the Netherlands at the end of October. However, its successor is already on the market in the form of the LR 1700-1.0. The first of these was delivered in June 2021. The new 700t crane meets the new requirements which the LR 1600/2 could no longer satisfy. New wind turbines with hub heights of 165m, requiring loads of over 100t to be hoisted to this height, are challenges to which Liebherr has responded with its new LR 1700-1.0. It is significantly more powerful than its predecessor and in some load cases even comes close to the LR 1750/2.

 

Departure of the last of its kind – the slewing platform of the last LR 1600/2 leaves the crane factory in Ehingen.
