Abstract

PURPOSE: To enable an pinpoint adjustment of a valve body in change-over control valve for an easy fine lowerng operation of a deck body in a controller of a deck tilting hydraulic cylinder by connecting a control lever and a control cable by means of an auxiliary control device.
CONSTITUTION: When a deck of a damp truck or the like is moved down a little to rest again from a position at which the deck is inclined uppermost to sprinkle gravel or drain water from gravel, a stopper 37 is caught by a control lever 23 to a rest, with the control lever 23 in neutral and a valve body 5 in neutral to block a P port only. In addition, a pinpoint adjusting handle 28 is turned left along with a screw rod 34 slightly to push an inner cable 25. The valve body 5 then makes a little movement to the right so that a large diameter member 20 in its back is finely opened from the sate where the member 20 closes the P port 6. As a flow of a return oil from a high pressure room 17 is restricted, the deck is lowered at a slow speed y the effect of a hydraulic layer 2.
