Cable Cars
A cable car is used to provide electric power to the large-scale excavator from the power line powering point. In order to increase the distances of the large-scale excavator from the connecting point several cable cars can be connected serially.
The equipment is designed and constructed individually based on the specific requirements and wishes of the customer (connecting voltage of the large-scale excavator, cable length) and it always reflects the specific conditions of the locations of deployment.
Each cable car consists of the undercarriage with the support frame and the superstructure with a cable drum and the support structure including the roof. The undercarriage consists of two caterpillar tracks with electromechanical or electrohydraulic drive. The cable car is powered either directly from the large-scale excavator or using the integrated power package.
