Material handling made easy
Dragline excavators from Liebher are used for a wide variety of applications with a dragline bucket, mostly for the mining of sand and/or gravel.
The dragline bucket is more or less cast as required through the swinging of the duty cycle crawler crane.
Duty cycle crawler cranes must endure especially high dynamic stresses during dragline operation.
Their robust steel construction not only increases the performance but also extends the service life making them perfectly suited for material handling operation.
The Interlock control system allows for power regeneration in dragline operation. This reduces the fuel consumption as well as the wear of the free-fall winch.
Thanks to the machine's optimized hydraulic system the size of the primary source can be reduced without negative impact on the turnover.
The efficiency is thus significantly increased while fuel consumption is decreased.
Special attention was given to the uncomplicated and economic transportation on all roads in accordance with current international transport regulations.
Thanks to minimum set-up work the machine can be quickly mobilized between jobsites so promoting economic deployment.
