PURPOSE: To enhance the safety of a handrail by measuring load applied to the handrail at the time of use and calculating support mount strength corresponding to actual use, by detecting the bending, distortion, tensile and compression stress generated in the mount support by each sensor mounted to the mount support.
CONSTITUTION: A sensor 1 for detecting bending stress generated in an up-and- down direction, a sensor 2 for detecting bending stress generated in a left-and- right direction, a sensor 3 for detecting torsion stress around an axis and a sensor 4 for detecting tensile stress and compression stress generated in the direction along the axial direction are provided to the peripheral surface of a mount support 5. Various stresses detected by the sensors 1W4 are measured by a dynamic stress gauge 7 and the measured values are recorded, for example, on a data recorder 8 or a pen recorder 9. In actual measurement, a measuring person grasps a handrail and takes various postures to perform measurement and, further, measurement is performed while variously changing the height of the handrail 6.
