The Utility Pole Trailer series from Felling Trailers offer several payload capacities and can be manufactured with a single- or tandem-axle configuration, both with dual wheels. All can be equipped with air brakes if needed. An industrial-grade energy chain houses both the electrical cable and the air lines. There’s no operator intervention needed when extending or retracting the trailer tongue, virtually eliminating the possibility of damaging the electrical cord or air lines. From the center bolster back is a 12-gauge steel floor with grouped perforations in each corner for drainage and small debris clean-out. 866-213-2949; www.felling.com
