Abstract
The invention relates to a telescopic push arm (11a, 11b) for a load-receiving means (9) mounted on a vertically adjustable lifting platform (8) of a conveying vehicle for storing an auxiliary loading means (1) in or removing it from a shelf storage (3b), with a support frame (14a, 14b) and a carriage (15a, 15b) adjustable relative to the latter, said carriage being provided with a servo-drive (50a to 50e) and/or sensor, whereby the servo-drive (50a to 50e) and/or the sensor are connected to an electrical interface (52) within the area of the support frame (14a, 14b) via a transmission means (20) for transmitting electrical energy and/or electrical signals. The transmission means (20) for transmitting electrical energy and/or electrical signals is formed by a sliding-line arrangement and a sliding-body arrangement (16, 18), or transmitting and/or receiving units, whereby for transmitting energy and/or signals from the interface (52) to the servo-drive (50a to 50e) and/or sensor (51), an electrical sliding contact (17) is formed between the sliding-line arrangement and the sliding-body arrangement (16, 18), or an electromagnet field is generated between two transmitting and/or receiving units.
