Abstract

A concrete transporting and placing vehicle wherein the frame of the material receiving body is slidably seated on a sub-frame that is fixed to the chassis of a truck, for movement by a hydraulic cylinder, about a fixed vertical axis, either to the left or the right, from a centered transport position aligned with the truck chassis to a diagonal discharge position in which the material discharge mouth at the rear of the body is at one side or the other of the vehicle; depending upon whether the body frame was shifted to the left or the right; and wherein upon return of the body frame to its transport position, a locking pin automatically engages to releasably hold the body frame in its transport position, the locking pin being automatically retracted to release the body frame for movement from its transport position, concomitantly with pressurization of the cylinder to effect such movement.

Dependent claims

In a material transporting vehicle of the type having a chassis and a body especially designed to hold a sizable volume of material to be transported, mounted on a body frame having parallel sides and front and rear ends, the body having a discharge mouth at one end thereof, and means mounting the body frame with the body thereon on the chassis of the vehicle in a manner that enables the discharge mouth of the body to be directed to either side of the chassis without substantially shifting the center of gravity of the loaded body with respect to the chassis, said means comprising:

A. rigid supporting structure fixed with respect to the chassis, said structure including cantilevered arms that project laterally beyond the sides of the chassis at spaced intervals along the length thereof, said cantilevered arms as well as the rest of said rigid structure having coplanar top surfaces;
B. the body frame having a bottom surface all portions of which lie in a common plane and slidably set upon the coplanar top surfaces of said rigid structure;
C. pivot means connecting the body frame with said rigid supporting structure, the axis of said pivot means being fixed with respect to said rigid supporting structure and normal to the plane of the slidably engaged surfaces of the body frame and rigid supporting structure and substantially intersecting the center of gravity of the body;
and
D. power means reacting between the body frame and the chassis, operable to swing the body frame about the axis of said pivot means from a transport position parallel with the sides of the chassis to either a right or left diagonally disposed position, in each of which the discharge mouth of the body is spaced laterally a substantial distance from the centerline of the vehicle chassis and in each of which the body frame is solidly supported by said rigid supporting structure.

In a material transporting and placing vehicle of the type having a chassis which includes parallel side rails, and a body especially designed to hold a sizable volume of concrete, mounted on a body frame having parallel sides and front and rear ends, the body having front and rear ends with a discharge mouth at one end thereof, and means mounting the body frame with the body thereon on the chassis of the vehicle in a manner that enables the discharge mouth of the body to be directed to either side of the chassis without substantially shifting the center of gravity of the loaded body with respect to the chassis, said means comprising:

A. a rigid sub-frame having front and rear ends and formed of elongated parallel side members spaced apart substantially the same distance as are the parallel side rails of the vehicle chassis, and cross members connecting said elongated parallel side members at spaced intervals along the length thereof, certain of said cross members having end portions that project beyond the parallel side members,
each of said members that collectively form the rigid sub-frame having a top surface, and all of said top surfaces lying in a common plane;
B. means securing the elongated parallel side members of said rigid sub-frame to the top of the parallel side rails of the vehicle chassis,
the body frame having a bottom surface all portions of which lie in a common plane and slidably seat upon the coplanar top surfaces of the members that collectively form said rigid sub-frame;
C. pivot means connecting said body frame with said sub-frame, with the axis of the pivot vertical and substantially intersecting the center of gravity of the body;
and
D. power means reacting between said frames and operable to slide the body frame about the axis of said pivot means from a transport position in which its sides are parallel with the side rails of the chassis to either a right or left diagonally disposed position, in each of which the discharge mouth of the body is spaced laterally a substantial distance beyond the centerline of the vehicle chassis and the body frame is solidly supported by the rigid sub-frame.
