    • The invention relates to a lifting device, especially a mobile lifting device, for lifting loads, vehicles or the like, said lifting device comprising a lifting column (14), a support (21) which is guided by the lifting column (14) and on which a load carrying means (22) can be arranged, and a drive unit (18) which can be controlled via a control unit (17) and which moves the support (21) up and down in relation to the lifting column (14). At least one lower guide element (43) is mounted on the lower end of the support (21) or on the load carrying means (22) and is supported on the lifting column (14) and can be displaced together with the support (21) during a lifting movement. At least one upper guide element (41) is mounted on the upper end of the lifting column (14) or in the vicinity of said upper end and is fixed in place on the lifting column (14) during the lifting movement of the support (21) and supports the support (21).

    • A computer-controlled robotic platform with a collapsible lifting arm that positions a non-destructive inspection (NDI) sensor for scanning inside tunnel regions of a composite structure such as an integrally stiffened wing box. The lifting arm of a modified scissor lift mechanism can be collapsed to a very low height to pass through narrow sections of the integrally stiffened wing box, and also extended by more than a factor of three to reach the maximum height of the wing box tunnels. The system performs a vertical position sensing and control process that uses inverse kinematics to enable position control using data from a standard rotational encoder on the motor to determine vertical position. The system produces simulated encoder pulses that represent unit vertical displacements of a distal portion of a modified scissor lift mechanism using a forward kinematics equation in which the rotation angle of a lead screw is an input variable.
    • 具有可折叠提升臂的计算机控制的机器人平台,其定位用于在复合结构(例如整体加强的翼盒)的隧道区域内扫描的非破坏性检查(NDI)传感器。 改进的剪刀提升机构的提升臂可以折叠到非常低的高度以穿过整体加固的翼盒的狭窄部分,并且还延伸超过三倍以达到翼盒隧道的最大高度。 系统执行垂直位置检测和控制过程,该过程使用反向运动学来使用来自马达上的标准旋转编码器的数据来进行位置控制,以确定垂直位置。 该系统产生模拟编码器脉冲,其表示改进的剪式提升机构的远端部分的单元垂直位移,其使用前导运动学方程,其中导螺杆的旋转角度是输入变量。
