Abstract: A system for attaching a material container to different vehicles and measuring a load on the vehicles, each of the vehicles having chassis members. The system comprises a hydraulic system configured to control operation of the material container, a control system configured to control the hydraulic system, and a load indication system configured to measure the load on the vehicles, wherein the load indication system is operably connected to the control system to provide load information for controlling the hydraulic system and material container.

Abstract: A sub frame assembly for attaching a material container to different vehicles each having a first and second generally parallel chassis member wherein the chassis members of the different vehicles have different spacings. The sub frame assembly comprises at least one frame rail associated with each chassis rail, at least a first and second cross member attached to the frame rails to hold the frame rails in a generally fixed relationship, wherein the cross members space the frame rails at a distance which corresponds to the chassis frame spacing of a respective vehicle.
