Abstract
A neutral stop device is provided which prevents the accidental lowering of a truck bed when the spool of the hydraulic valve system is positioned in a neutral location and any force acts on a pull-out cable running from the spool to the truck bed. A stop device is provided having two annular rings, each of which surround a different end of the spool, said rings being connected by a spacer means. Each of the annular rings is adapted to interact with a snap ring provided on the end of the spool to restrict the movement of the spool to a preselected range. The stop device is activated by a cable attached to the truck bed and is moved to a position which prevents the spool from moving from a raise location to a lower location.
