ABSTRACT:
A positioning apparatus using a hydraulic actuator. For positioning an object to the desired position with high accuracy, the apparatus has means for computing the position at which the operation for stopping the operation of the hydraulic actuator is to be carried out in order to position the object at the desired position. The operation of the hydraulic cylinder is rendered to stop when the position has reached the computed position, whereby to enable the object to accurately position at the desired position at relatively high speed.
