Document Type and Number:
Japanese Patent JP5592832
Kind Code:
B2
Abstract:
A vehicle control device 50, a controller 100, an inverter control device 30 and a steering control device 32 constitute a control device 200 which controls elevation of sliders 4Ra and 4La of power collectors 4R and 4L based on information detected by a trolley wire detecting device (camera) 15. The control device 200 calculates positional relationship between a slider and a trolley wire 3R/3L based on the information detected by the trolley wire detecting device. When the slider has deviated from a prescribed range for being in contact with the trolley wire, the control device executes control to prohibit an operation for elevating the sliders or to lower the sliders when the sliders have been elevated. With this configuration, an electrically driven dump truck capable of lightening the operating load on the driver during the trolley traveling is provided.
