ABSTRACT:
A suspension system for a dump truck which is to be connected to a paver using a truck hitch. In one example, a system for connecting a dump truck to a paver includes a liftable and steerable suspension of the truck, the suspension having an adapter with a laterally outwardly facing concave side. A truck hitch of the paver engages the concave side of the adapter to attach the truck hitch to the suspension. In another example, a method of connecting a dump truck to a paver includes the steps of: interconnecting a hydraulic actuator between a frame of the truck and an axle of a suspension of the truck to thereby transmit a load from the frame to the axle; then raising a bed of the truck, the load increasing as the bed is raised; and increasing pressure in the hydraulic actuator in response to the increasing load.
