In a boom lift vehicle comprising a vehicle equipped with a travel apparatus and capable of travel, a boom that is attached to said vehicle and is at least vertically tiltable and horizontally rotatable, and a work platform attached to the distal end of said boom; a travel and rotation control device for controlling the travel of said vehicle and/or the rotation of said boom. The control device includes a travel command means for outputting commands for the travel of the vehicle; boom rotation command means for outputting commands for rotationally operating the boom; position detection means for detecting the position of the work platform with respect to said vehicle; and control means for calculating the movement speed of the work platform at a position detected by the position detection means according to a travel command issued by the travel command means and/or a boom rotation command issued by the boom rotation command means, and controlling the travel of the vehicle and/or the rotation of the boom so that the movement speed of the work apparatus does not exceed a predetermined base speed.
