Abstract: Clutch controlling apparatus which may be utilized in industrial-type vehicles, such as for example, forklift trucks, for controlling the vehicle during inching operations includes a source of fluid pressure, a fluid pressure-type clutch fluidically connected to the pressure source, an inching valve disposed within the fluid circuit connecting the fluid pressure source and the clutch mechanism which controls the degree to which the clutch mechanism is actuated and which in turn is actuated to a degree which is dependent upon the depression of the vehicle brake pedal, and limiting means for selectively inactivating the inching valve such that the inching valve is inoperative independent of the brake pedal.In this manner, when the vehicle is being operated on level ground, the inching operation is performed by intermittently depressing the brake pedal which actuates the inching valve which in turn deactivates the clutch mechanism thereby terminating driving torque to the vehicle transmission.
