Patent number: 9481250Abstract: 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.Type: GrantFiled: October 31, 2012Date of Patent: November 1, 2016Assignee: SANDVIK MINING AND CONTRUCTION OYInventors: Jukka Osara, Samuli Kouhia

Patent number: 8869923Abstract: 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.Type: GrantFiled: May 24, 2011Date of Patent: October 28, 2014Assignee: Sandvik Mining and Construction OyInventors: Jukka Osara, Juha Piipponen, Jarno Kuittinen, Timo Niemi

Publication number: 20130214928Abstract: The invention relates to a rock drilling rig, a method for transfer drive of the rock drilling rig, and a speed controller. The rock drilling rig includes combustion-engine-free drive equipment which includes a plurality of electric components for implementation of the transfer drive. The control unit of the rock drilling rig includes load monitoring which monitors the load of the components during the transfer drive. Load monitoring allows the electric driving system to be intentionally overloaded for a period of time limited in advance. A user interface of the control unit comprises a speed controller whose control element has a first control range, where operation takes place in the rated load range, and a second control range, where operation takes place in the overload range.Type: ApplicationFiled: May 24, 2011Publication date: August 22, 2013Applicant: Sandvik Mining and Construction OYInventors: Jarno Kuittinen, Jukka Osara
