Electric drive dump truck

An electric drive dump truck that travels by contacting, with trolley lines, power collection units configured to be moved up and down by lifting devices and receiving electrical power from the trolley lines, the electric drive dump truck comprising:

• a position detection device configured to detect a position of the electric drive dump truck;
• a vehicle speed detection device configured to detect a vehicle speed of the electric drive dump truck;
• a memory configured to store a position of the trolley lines and a time of upward movement from when the power collection unit starts to move upward to the trolley lines until the power collection unit contacts with the trolley lines start moving up;
• and
• a controller configured to output a signal indicating that the power collection units can be moved upward to the trolley lines based on the position and vehicle speed of the electric drive dump truck, the position of the trolley lines, and the upward movement time;
• wherein the memory includes a region for storing, as the position of the trolley lines, a position at which the electric drive dump truck enters a travel section in which the trolley lines are provided, and
• wherein the controller is further configured to correct the position at which the electric drive dump truck enters based on a curvature of a road surface in the travel section.
