Abstract
A transport vehicle includes a body; a lift platform that includes a holder to hold an article, the lift platform being ascendable and descendable with respect to the body; a lift driver that raises or lowers the lift platform by feeding out or taking up a flexible suspension support; a sensor provided in the lift driver and emits a detection wave having directivity toward a certain lower position; a lateral extender that causes the lift driver to project laterally from the body while providing cantilever support for the lift driver; and a corrector that corrects a shift in an emission direction of the detection wave that arises from bending of the lateral extender in a state in which the lift driver is caused to project laterally from the body by the lateral extender.

A transport vehicle comprising:
- a body;
- a lift platform that includes a holder to hold an article, the lift platform being ascendable and descendable with respect to the body;
- a lift driver that raises or lowers the lift platform by feeding out or taking up a flexible suspension support;
- a sensor provided in the lift driver and emits a detection wave having directivity toward a certain lower position;
- a lateral extender that causes the lift driver to project laterally from the body while providing cantilever support for the lift driver;
- and
- a corrector that corrects a shift in an emission direction of the detection wave that arises from bending of the lateral extender in a state in which the lift driver is caused to project laterally from the body by the lateral extender.
A transport method that transports an article by a transport vehicle, the transport vehicle including:
- a body;
- a lift platform that includes a holder to hold the article, the lift platform being ascendable and descendable with respect to the body;
- a lift driver that raises or lowers the lift platform by feeding out or taking up a flexible suspension support;
- a sensor provided in the lift driver and emits a detection wave having directivity toward a certain lower position;
- and
- a lateral extender that causes the lift driver to project laterally from the body while providing cantilever support for the lift driver,
- the transport method comprising:
- when the lateral extender causes the lift driver to project laterally from the body, correcting a shift in an emission direction of the detection wave that arises from bending of the lateral extender.
