INGOT CARRIER AND TRAVELING METHOD THEREOF

摘要

<P>PROBLEM TO BE SOLVED: To provide an ingot carrier and a traveling method thereof which allow linear motion without revising a drive device of a work machine or controlling the traveling at a high level by adding relatively simple members. Ž<P>SOLUTION: A pair of left and right guide rollers 50 to 53 are provided at the back and front of a track frame 2 of a lower part moving body of a self-propelled work machine. A guide rail 72 is arranged on the ground. The guide rail 72 is held between the left and the right guide rollers 50 and 51 and 52 and 53 when the work machine moves. Advance side oil pressure circuits of the left and the right driving oil pressure motor of a lower part moving body 1 and backward side oil pressure circuits are linked by switch valves respectively, and the carrier moves straight along the guide rail 72.
