  • Rock drilling rig and method for downhill drive
    Patent number: 8869923
    Abstract: The invention relates to a rock drilling rig and a method for downhill driving of a rock drilling rig. The rock drilling rig comprises electric drive equipment, the drive motor of which serves as a primary brake in long-term downhill driving. The drive motor thus converts kinetic energy into electric energy, with which an energy storage is charged. To consume surplus electric energy, a hydraulic system or a compressed air system is turned on. A hydraulic pump and a compressor (54) are driven by an electric motor.

  • MINING VEHICLE
    Publication number: 20140262664
    Abstract: A mining vehicle includes electric components, devices or machines operating at alternating voltage and having a specific nominal voltage. Power is fed to the mining vehicle from an alternating current network with a specific voltage level. The mining vehicle further includes a transformer arranged to transform the voltage level of the alternating current network into the nominal voltage. When a voltage higher than the nominal voltage is fed to the transformer, the transformer lowers this higher voltage to the nominal voltage. When a voltage lower than the nominal voltage is fed to the transformer, the transformer raises the voltage to the nominal voltage. The transformer is arranged to feed the electric component, device or machine both when a voltage lower than the nominal voltage is fed to the transformer and when a voltage higher than the nominal voltage is fed to the transformer.
