A system for controlling the RPM of an engine and an outrigger of a crane vehicle is provided to use a remote control acceleration signal selecting function and an accelerator provided in an electronic engine by remotely selecting an acceleration signal to control the RPM of the electronic engine. In a system for controlling the RPM of an engine and an outrigger of a crane vehicle, an outrigger controller(153) analyzes data transferred from a multi-data transmitter(77) and determines whether a PTO enable signal(75) is active. Drive signals of solenoids(85,86,87,88) of an outrigger operating cylinder are generated through output ports corresponding to input information of a cabin outrigger control panel(120). The control of the RPM of an engine is performed by an accelerator pedal installed in the cabin. An outrigger unit is operated by determining whether a multi-stage boom is positioned so that the cabin outrigger work is promptly performed, a conventional crane work is performed, and overturn of equipment can be prevented during the outrigger work. |
