PURPOSE:To stabilize the running and driving power of a link device and prevent guide rail from wearing abnormally by a method wherein a surface pressure measuring apparatus is installed at the arbitrary position of the guide rail, which forms the running path of the link device when it runs under its contracted state and controls the link device. CONSTITUTION:The movement of link device 1 is controlled with guide rail 2 under the contracted state of the link device. The reaction 3 of the guide rail 2 is applied to bearings 4. A surface pressure measuring apparatus 5 is installed at the arbitrary position of the guide rail 2 so as to measure the reaction 3 of the guide rail developed at the passing of the link device 1 on a guide rail 6 with a control panel. The apparatus 5 is constituted so as to inform with alarm, warning light or the like, when measured value increases remarkably over the value of load at the initial stage of the starting of the running of the device concerned. |
