Claims

[Scope of utility model registration request]

A control device for a lifting cylinder, comprising a double-acting cylinder that raises and lowers an article loading platform, piping that connects both fluid inlets and outlets of the double-acting cylinder to an air source and the atmosphere, and a switching valve that switches the piping. A pressure reducing valve is interposed in the piping on the side that supplies air when the article loading platform is lowered, and the pressure reducing valve is connected to the double-acting cylinder side connecting member, the switching valve side connecting member, and these. The double-acting cylinder-side connecting member includes an adjusting nut screwed into the left-hand thread and right-hand thread separately turned on the outer periphery of both members, and a valve seat biased by a spring is loosely fitted on the inner periphery of the double-acting cylinder side connecting member. The switching valve side connecting member is a control device for a lifting cylinder, in which a valve body that contacts the valve seat is accommodated therein.
