為了提高該雙主梁門式起重機大車運行的可靠性及安全性，防止柔性鉸支座轉動角度過大，造成鋼結構的損傷，因此必須實時測量鉸支座的轉動角度，并判斷每一時刻的轉動角度是否在允許范圍之內，(通常只允許鋼性腿和柔性腿行走的距離之差在±3‰跨度內)并實時糾偏。此角度的測量值應是角度值，而不是角度變化量，不應因停電而丟失角度值，因此必須安裝編碼器，鑒于國產(chǎn)的1024/每轉 的編碼器產(chǎn)品質量還不穩(wěn)定，容易產(chǎn)生誤碼等原因，因此建議采用進口（或合資）產(chǎn)品，如日本光洋、德國海德漢、倍加福等，以保證電氣控制的可靠性。

In order to improve the reliability and safety of the gantry crane with double main beams and prevent the flexible hinge support from rotating too much and causing damage to the steel structure, it is necessary to measure the rotation angle of the hinge support in real time and judge whether the rotation angle at each time is within the allowable range (usually only the difference between the walking distance of the rigid leg and the flexible leg is allowed to be within ± 3 ‰ span) and correct the deviation in real time. The measured value of this angle should be the absolute angle value, not the angle change, and the angle value should not be lost due to power failure. Therefore, the absolute value encoder must be installed. In view of the unstable product quality of the domestic 1024 / rev absolute value encoder, which is prone to bit error and other reasons, it is recommended to use imported (or joint venture) products, such as Japan Guangyang, Germany heidenham, beijiafu, etc., to ensure the reliability of electrical control.
