    • A system for positioning a work point in three dimensional space has at least three reeving systems (27, 29, 30) spaced apart from one another, with each reeving system having an adjustable support element (31, 32, 34) connected to it. These support elements are also connected to the work point (35), with the length of the support elements between the work point and the reeving determining the work point's location. Associated with each reeving determining the work point's location. Associated with each reeving system is an actuator adapted for releasing and taking up the support element. A control system controls the actuators to release and take up each of the support elements to move the work point with respective to at least three spatial coordinate axes while controlling at least one motion parameter of the work point in a predetermined manner.
    • 用于在三维空间中定位工作点的系统具有彼此间隔开的至少三个卷绕系统(27,29,30),每个卷绕系统具有连接到其上的可调节支撑元件(31,32,34)。 这些支撑元件也连接到工作点(35),支撑元件的长度在工作点和压板之间确定工作点的位置。 与每个确定工作点的位置相关联。 与每个卷绕系统相关联的是适于释放和吸收支撑元件的致动器。 控制系统控制致动器以释放和吸收每个支撑元件,以相应于至少三个空间坐标轴移动工作点,同时以预定方式控制工作点的至少一个运动参数。
