Abstract
This invention relates to a cargo-handling vehicle equipped with a cargo-handling apparatus and having a single power plant adapted to commonly drive a hydraulic pump for driving and a hydraulic pump for cargo-handling. A driving command signal in the form of an analog or digital electric signal output from a driving operation device in response to the operated amount thereof is output to first conversion means. The first conversion means converts the driving command signal or the operated amount of the driving operation device to power plant revolution data for driving which is determined by the preset function, and then outputs the data to selection means. A cargo-handling command signal in the form of an analog or digital electric signal output from a cargo-handling operation device in response to the operated amount thereof is output to second conversion means. The second conversion means converts the cargo-handling command signal or the operated amount of the cargo-handling operation device to power plant revolution data for cargo-handling which is determined by the preset function, and then outputs the data to the selection means. The selection means selects at least one of t…
