10/29/2021 The end of an era – the last LR 1600/2 leaves the Liebherr Plant in Ehingen
- The 223rd and last LR 1600/2 crawler crane leaves the factory in Ehingen
- First delivered in 2008, the boom configurations grew along with its range of jobs
- Successor LR 1700-1.0 in action around the world since June 2021
The end of an era after 220
The 600 tonne 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.
LR 1600/2 large volume wind power crane
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 130 to 135 metres. In this configuration, the crane had a main boom of 138 metres and a fixed jib of 12 metres. This was the benchmark for turbines with a hub height of 135 metres. Over the next few years, however, the size of wind turbines increased dramatically up to hub heights of 150 metres 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 150 metres.
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 600 tonne 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.
Successor standing ready
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 700 tonne crane meets the new requirements which the LR 1600/2 could no longer satisfy. New wind turbines with hub heights of 165 metres, requiring loads of over 100 tonnes 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.
