Abstract
A quint configuration fire apparatus includes a ladder assembly and a single rear axle coupled to a chassis. The single rear axle includes either a single solid axle configuration extending laterally across the chassis or a first axle having a first constant velocity joint and a second axle having a second constant velocity joint. The ladder assembly is extensible to provide a horizontal reach of at least 90 feet and a vertical height of at least 95 feet and configured to support a tip load of at least 750 pounds. A water tank is configured to contain at least 500 gallons of water. The center of gravity of at least one of the chassis, a body assembly, a pump, and the water tank are positioned to counterbalance a moment generated by the tip load with the ladder assembly extended to the horizontal reach of at least 90 feet.
