作業部の昇降制御装置。 A work traveling machine comprising a lifting control means for raising and lowering a working part connected to the machine body so as to be raised and lowered in accordance with the swinging of a hydraulically operated lift arm based on the operation of an automatic return type lifting operation switch. The lifting control means is set to a low speed operation mode in which the working part is raised and lowered at a low speed at the beginning of the raising and lowering operation, and a high speed operation mode in which the working part is raised and lowered at a high speed thereafter, and the raising and lowering control means further includes: mode switching means for switching the operating mode from a low-speed operating mode to a high-speed operating mode based on the fact that the lift operation switch has been operated for a set time or more; and a set time for correcting the set time of the mode switching means based on the engine rotation speed. 1. A lifting and lowering control device for a working part in a working traveling machine, characterized in that a correction means is provided.
