PROBLEM TO BE SOLVED: To provide a carrier vehicle which can improve productivity by shortening a cycle time. SOLUTION: The carrier vehicle comprises a controller section 20. The controller section 20 comprises a first inverter controller section 22 and a second inverter controller section 23. The first inverter controller section 22 drives a first traveling motor 26 and a second traveling motor 27, while the second inverter controller section 23 drives a revolving motor 28 to control a transfer section. When goods are carried in, the controller section 20 calculates the traveling time Tr1 from the present position to a target position. Then, the controller section 20 compares Tr1 with twice the revolting time Tt of the transfer section. When Tr1≥Tt×2, the controller section 20 controls the second inverter controller section 23 so as to revolve the transfer section when traveling starts. During traveling, the controller section 20 calculates the time Tr2 to the target position and the revolting time Tt. When Tt becomes equal to or larger than Tr2, the controller section 20 controls the second inverter controller section 23 so as to start to revolve the transfer section. COPYRIGHT: (C)2004,JPO |
