Lechevallier, EP0691911 describes a removable frame for loading, unloading and moving container's of goods on trucks or wagons without typical lifting machinery such as cranes, gantries and such. It permits unload directly onto the ground. The invention is characterized by arrangement of a frame encompassing the load. Two lifting surfaces are provided with lateral spacing between them and are placed transverse of the vehicle's axle. Each of the surfaces is lifted by a telescoping jack and facility for locking the load in place is provided. The prior art teaches a very wide range of materials storage and handling systems. However, the prior art does not teach that an actuated clamping device may be mounted onto a truck for clamping panel goods for transport. The present invention fulfills these needs and provides further related advantages as described in the following summary. SUMMARY OF THE INVENTION The present invention teaches certain benefits in construction and use which give rise to the objectives described below. The present invention provides an apparatus for carrying panel materials adjacent to a truck side panel and comprises a stationary workpiece resting surface mounted on the truck side panel and a movable workpiece clamping and supporting device positioned adjacent to the stationary workpiece resting surface and mounted to the truck. A motive device such as a motor engages the truck and is connected for moving the workpiece clamping and supporting device toward and away from the workpiece resting surface for sandwiching a workpiece between the workpiece resting surface and the workpiece clamping and supporting device for enabling the truck to transport the workpiece.. A primary objective of the present invention is to provide a panel carrying device having advantages not taught by the prior art. Another objective is to provide such a device that is mounted to a truck body and holds the panel for transport. A further objective is to provide such a panel carrying device that is able to open to accept a load and to close to clamp the load on a truck. Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention. BRIEF DESCRIPTION OF THE DRAWING The accompanying drawings illustrate the present invention. In such drawings: FIGURE 1 is a perspective view of the preferred embodiment of the present invention showing how a panel may be inserted into the invention for transport; FIGURE 2 is similar to Fig. 1 with arrows illustrating an opening movement of the invention for inserting a panel into the invention; FIGURE 3 is similar to Fig. 2 with arrows illustrating a closing movement for clamping a panel in the invention; FIGURE 4 is a bottom plan view with an arrow showing the manner in which the invention moves for opening; and FIGURE 5 is a view similar to that of Fig. 4 with an arrow showing the manner in which invention moves for clamping panels. DETAILED DESCRIPTION OF THE INVENTION The above described drawing figures 1-5 illustrates the invention, an apparatus for carrying panel materials such as gypsum wallboard or plywood sheets adjacent to a truck side panel 5. The apparatus mounts onto the truck side panel 5 and secures one or more sheets or panels which constitute the workpiece 7 for transport.
