摘要： Transport carts without internal drive which are bound to rails are moved in a returning system on a transport line from a common main drive. In the end area of the transport line, a secondary drive system is provided so that the transport carts are transferrable along a vertical curve into an inverted position onto a return line which is disposed parallel beneath the transport line and is provided with a second main drive system.
