74 is mounted on top of a plurality of brackets 76 which are in turn mounted to the top surface of the housing 68 a pulley 78 is mounted to the shaft 80 which extends from the winch 74 a continuous belt 82 is positioned around the pulleys 70 and 78 and transmit power from the motor 66 to the winch 74 a pivotally mounted idler pulley 84 is mounted to one of the brackets 76 and maintains tension on the belt 82 a cable 86 extends from a spool 88 which is mounted within the winch 74 downward through a pulley block 90 which is mounted to the underside of the second brace 22 and extends forwardly therefrom to a fixed object not shown a certain distance along the form 40 when the motor 66 is connected to a source of electrical power not shown the winch 74 rewinds the cable 86 thereby propelling the apparatus 10 forwardly along the form 40 and pavement 42 an internal combustion engine may be used in place of the electric motor 66 and then the idler pulley 84 would provide a clutch means for the winch 74 to make a run of curbing the apparatus 10 is placed on top of the still wet pavement 42 with the wheels 44 and 48 engaging the top edge.
