    • In an apparatus for correcting deflection produced in a construction due to the weight of the construction or movement of a movable member supported by the construction, a condition data representing the deflection associated with the moved position of the movable member is stored in a memory section of a correction controller. The movement of the movable member is detected by a position detector and a position signal is generated from the position detector. A command signal is supplied to a calculator and the position signal is received in the calculator synchronized with the command signal. The condition data is accessed by the calculator with the received position signal and is processed into a correction data. A correction data is supplied to a proportional control electromagnetic valve and a hydraulic cylinder for applying a force onto the construction is regulated by the valve to correct the deflection of the construction.
    • 在用于校正结构中产生的偏转的装置中,由于构造所支撑的可动构件的重量或移动的重量,表示与可移动构件的移动位置相关联的偏转的条件数据被存储在 校正控制器。 通过位置检测器检测可动部件的移动,从位置检测器产生位置信号。 向计算器提供命令信号,并且与计时器同步地接收位置信号。 条件数据由具有接收到的位置信号的计算器访问,并被处理成校正数据。 校正数据被提供给比例控制电磁阀,并且用于向结构施加力的液压缸由阀调节以校正结构的偏转。
