The platform sheave has a wide, shallowgroove so that the wire can shift from side to side. After the trolley wire has been fastened or anchoredall that is necessary is to raise the tower to the desiredheight, set the tension clamp, and start the car, whenthe wire will be paid out perfectly straight and freefrom kinks. The wire can be run without pulling orlifting, and as everything connected with the tower is. THREE-IN-ONE CAR—FIG. 4, PLATFORM OF LINE TOWER
