Abstract
The disclosure relates to an overhead line system for supplying electricity to the drive of one or more construction machines for piece good or bulk material transport, wherein the overhead line comprises at least one pair of lines which extend parallel along the route, carry current with opposing polarity and which can be electrically contacted by corresponding current collectors of the construction machines, characterized in that each line is provided at the end with at least one guide forming a feed channel for receiving the head of the current collector, the feed channel converging in the direction of the associated line.
Claims20
An overhead line system for an electrical supply of a travel drive of one or more construction machines for a transport of unit load and bulk load, wherein the overhead line system comprises at least one line pair of lines that run in parallel along a driving route, that carry current of opposite polarity, and that can be electrically contacted by corresponding current collectors of the one or more construction machines,
- wherein each line of the at least one line pair of lines is equipped at a respective end side with a respective guide aid forming a supply channel for mounting and guiding a head of a current collector, with the supply channel converging in a direction of the line, the guide aid configured to accommodate the head of the current collector in the supply channel and guide the head along the supply channel until the head contacts the line;
- and at least one current collector is actively movable in vertical and horizontal directions.
An overhead line system for supplying electricity to a vehicle, comprising:
- an overhead line configured to conduct electricity;
- and
- a guide aid arranged at a line start of the overhead line, the guide aid comprising:
- a pair of triangular side walls;
- and
- a triangular upper side coupled to the pair of triangular side walls,
- the guide aid being open at a front side and at a bottom of the guide aid, and each triangular side wall of the pair of triangular side walls and the upper side each converge and narrow from the front side to an end of the guide aid arranged at the line start, such that the guide aid is configured to accept a current collector and guide the current collector to mechanically contact the line start.
