Image is of two men in center foreground loading rock into the bed of a dump truck. A crane, in near foreground, has lifted a heavy wooden platform topped with several medium-sized rocks as the men guide it over the truck bed. Previously the platform was set on the ground and loaded by hand with rocks from the pile partially visible at right. The platform was then lifted over the side of the truck bed as seen here. and lowered down to the sideboard. The platform is attached to the crane with permanent cables on the right side and removable chains on the left. When the platform is settled on the edge of the truck, the chains will be unhooked and the right-side cables will be lifted to tip the rocks off into the truck bed. An empty dump truck is visible further down the road at right.
