In recent decades, Liebherr has demonstrated the quality and reliability of its electric technology with the success of its dedicated product ranges for mining, dredging and materials handling applications.
Today, the company is presenting two new local zero emission machines, the Liebherr R 976-E and R 980 SME-E electric crawler excavators.
The R 976-E electric crawler excavator, along with the R 980 SME-E, replaces the ER 974 B for mine and quarry extraction. The latest electric excavators to be developed and produced by Liebherr-France SAS in Colmar, France, they are not just converted diesel machines. The excavators and their electric power system were designed and produced entirely by Liebherr.
Robustly designed and capable of withstanding extreme conditions, they weigh 90 and 100 tonnes respectively and are available in backhoe and shovel versions. They stand out for their low noise level, optimum versatility and zero CO2/greenhouse gas emissions during operation.
The technology used in the R 976-E and R 980 SME-E offers a host of advantages. Thanks to its constant speed whatever the load, an excavator with an electric engine has a longer service life.
Also, the high availability of transient power for complex machine movements enables very high productivity. The R 976-E’s low-voltage electric squirrel-cage engine drives the hydraulic system.
