PROBLEM TO BE SOLVED: To provide a ball-lifting system wherein the attaching/detaching work of a carrying belt can be extremely easily performed. SOLUTION: On a plurality of tension rollers 31, 40 and 40, a carrying belt 15 is alternately wound around in order to impart a tension to the carrying belt 15. From among the tension rollers 31, 40 and 40, one tension roller 31 is pivotally supported by a fixed box 30 which is fixed to a lifting cylinder main body 12, in a manner to be rotatable. Then, other tension rollers 40 and 40 are pivotally supported by the front surface side of an openable/closable lid box 39 which is openably provided to the fixed box 30, in a manner to be rotatable. Thus, when the openable/closable box 39 is opened, the carrying belt 15 is released from a pinched state by the tension rollers 31, 40 and 40. Therefore, when the carrying belt 15 is attached/detached, the removal of the tension rollers 31, 40 and 40 becomes unnecessary, and the work can be extremely simply performed.
