A "road magnet" machine is described which is helping maintenance crews "comb up" between three and five tons of tire-damaging metal litter from roadsides. The unit consists of a hydraulically lifted, 96-in.-long magnetic bar mounted on the back of a Ford truck. Power for the magnet is provided by a 3KW DC generator furnishing 115 volts and 20 amps. The generator is belted to an air cooled engine. The magnet is switched while the engine is throttled back to avoid problems where the full load was interrupted and started. A hand-operated hydraulic system works the magnet into position. The use of the unit on a statewide basis is outlined. A daily report is made by the operator indicating the trunk highway road number, surface type, area covered, speedometer reading and the weight of scrap material accumulated.
