1343067 Bale handling vehicles SPERRY RAND CORP 19 April 1971 [31 March 1970] 25710/71 Heading B8E In the bale waggon described in Specification 1,284,103, the hydraulic circuit is modified to prevent the rolling rack moving rearwardly except when a stack of bales is being loaded on to the front end of the load bed by the transfer table. Because the pressure relief valve which permits fluid flow from the cylinder controlling the rolling rack to permit the rolling rack to be forced rearwardly by the bales being loaded also allows rearward movement when the bales are jostled by the waggon passing over rough ground, it is replaced by a valve which only opens to allow fluid to flow from that cylinder when there is pressure in the line to the cylinder which operates the transfer table (200).
