| 摘要 | An apparatus for moving a platform in horizontal and vertical directions relative to a base. The apparatus comprises a parallelogram structure comprising first and second parallelogram linkages each parallelogram linkage comprises first and second link arms and a hydraulic actuator to vary the geometry of the respective parallelogram linkage. A connecting member is connected between the parallelogram linkages to which a first end of each link arm and a first end of each hydraulic actuator are pivotally connected. The first ends of the hydraulic actuators and the first ends of the first link arms are connected to the connecting member along a first pivot axis. | ||
