The crane is designed to pick up 1,000 lb. at an 8-ft. out-reach, or with outriggers in position as shown 3,000 lb. at()-ft. outreach. The boom may Ije lowered to permit entranceof doorways. The outriggers are quickly adjusted, foldedand swung in beside the crane column when not in use. The truck is equipped with 21/^ in. by 3^ in. drivewheels and IS in. by 3^2 in. trailing wheels, all four ofwhich steer. Large wheels permit use in yards.
