| 摘要 |
The invention concerns a handling device for a cable (7) extending between a point of electrical connection (11) and a driver-less, electrically operated working vehicle or a working machine (1), across a surface. Guide and control means direct the vehicle (1) along a predetermined path (13, 15, 17) on the surface (2). The vehicle is provided with a cable storage means (4) and with cable-feeding means (6), said means controlled for coordination with the operation of the vehicle (1). The feeding means are arranged, at the pace of the vehicle speed, to so pay out the cable (7) from the vehicle as the latter moves away from the electrical connection point (11) and to so pull in the cable (7) as the vehicle moves closer to the connection point (11) that the path of movement of said vehicle (1) is always left unobstructed to allow the vehicle to carry out its working operations. |
