These new electric Material Handlers have been designed to meet the specific needs of industrial handling. A wide range of equipment and uppercarriages optimized for long working radius provide the ideal answer to all the demands which arise in the industry. The performance of the kinematic chain formed from components from our in-house production, combined with the power of the electric motor, maximize the performance of the machine when it comes to lifting power, precision, and speed of operation. The equipment’s performance is enhanced by the mobility provided by the crawler...

Reliability Backed by more than 30 years experience in the construction of electric excavators, Liebherr designed the new ER 934 C, ER 944 C and ER 954 C with the aim of providing top performance whatever the challenge might be. The structure of the machine, using components from our own manufacture for the electric drive, has been completely rethought, and so moves away from simply being an adaptation of a diesel-engine machine. Being intended for key functions in the organization of industrial sites, Liebherr electric Material Handlers provide a very high level of reliability. The service...

Comfort Helping the operator to concentrate on his work and get the best out of his machine is achieved by providing a comfortable driving position, good visibility, and a highly ergonomic layout of the controls. The new electric Material Handlers offer the same level of comfort as on the mobile excavators (arrangement of the controls, driver’s seat, climate control, large window areas, etc.). The electric motor system adds a further layer of comfort thanks to the low noise emissions and absence of vibration. For Liebherr, comfort also means ease of daily maintenance of the machine in terms...

Economy Investing in the acquisition of an electric Material Handler is a great long-term advantage. Constant increases in the costs of conventional energy sources are pushing up operating charges, and reducing profit margins considerably. Environmental criteria, in particular CO2 emissions, are also playing a constantly greater part in the choice of power systems and working methods. With the electric drive, Liebherr offers an economical alternative to conventional diesel-engine machines, and a solution with real respect for the environment. Also, the excavator is permanently available,...
