Abstract

PURPOSE:To shorten a time required for lifting a working machine and simultaneously prevent the generation of a shock at the time of stopping the working machine, by gradually stepwise reducing the rate of supplying electric power to a hydraulic control valve with the access of the working machine to the set limit of its upward movement. CONSTITUTION:A rate of supplying electric power to a hydraulic control valve which controls hydraulic power supplied to a lifting or lowering mechanism 19 is gradually reduced with the access of a working machine B to the set limit of its upward movement during its rising action. The working machine B rises at a high speed when it is apart from the limit of the upward movement, but the rising speed of the working machine B is gradually reduced with approaching to the limit of the upward movement.
