A self-propelled vehicle mounting a cantilevered conveyor truss for concrete and the like. An improved force balancing frame enables the vehicle to remain stable even though the truss conveyor is extended to maximum length and elevated to a high angle. Improved geometry enables the truss conveyor to be pivoted at a point above a cab mounted on a turntable of the vehicle and forward of the axis of rotation of the turntable, thereby facilitating the deposit of concrete on the conveyor. Polyethylene pads control the motion of the truss conveyors, especially when the truss conveyor is elevated to a high angle. A unique drive assembly enables a mid-section and fly section of the truss conveyor to be moved simultaneously with respect to a base section of truss conveyor such that the fly section moves at twice the rate of the mid-section.

Abstract

A self-propelled vehicle mounting a cantilevered conveyor truss for concrete and the like. An improved force balancing frame enables the vehicle to remain stable even though the truss conveyor is extended to maximum length and elevated to a high angle. Improved geometry enables the truss conveyor to be pivoted at a point above a cab mounted on a turntable of the vehicle and forward of the axis of rotation of the turntable, thereby facilitating the deposit of concrete on the conveyor. Polyethylene pads control the motion of the truss conveyors, especially when the truss conveyor is elevated to a high angle. A unique drive assembly enables a mid-section and fly section of the truss conveyor to be moved simultaneously with respect to a base section of truss conveyor such that the fly section moves at twice the rate of the mid-section.
