Title:
FORKLIFT
Document Type and Number:
WIPO Patent Application WO/2015/083937
Kind Code:
A1
Abstract:
The present invention relates to a forklift. A forklift, according to the present invention, is controlled such that, when a running speed reaches or becomes higher than a predetermined running speed, the pressure of a hydraulic fluid that is provided in a steering unit is reduced. Therefore, in order to perform desired direction conversion, turning operation of a steering wheel must be carried out relatively more than when running at a low speed. Therefore, straight running performance can be improved by reducing the sensitivity of direction conversion of the forklift due to operation of the steering wheel.
