Claims

[Scope of utility model registration request]

On the swivel base attached to the vehicle so that it can be rotated freely,
An aerial work vehicle comprising a boom equipped with a bucket at its tip so that it can be driven up and down, and in particular, for operating a hydraulic actuator that drives the swivel platform and a control valve device of the hydraulic actuator that drives the boom. Control of the engine accelerator of the aerial work vehicle, which is equipped with a lower operating device and an upper operating device on the swivel platform and the bucket, respectively, and a hydraulic pressure generating device that is driven by an engine and generates actuator drive hydraulic pressure. The apparatus includes a lower setting device and an upper setting device for setting the operation position of an accelerator actuator that drives an accelerator mechanism of the engine, and which is attached to the swivel base and the bucket, respectively, and the upper operating device and the lower operating device. A lower operation detection means and an upper operation detection means are respectively provided for detecting whether or not the accelerator actuator is in an operating state, and when the upper operation detection means detects the operating state, the accelerator actuator and when the lower operation detecting means detects an operation of the lower operating device, the lower operation detecting means, the upper operation detecting means, and the lower 1. A control device for an engine accelerator of an aerial work vehicle, characterized in that a setting device, an upper setting device, and an accelerator actuator are configured in association with each other.
