[0004] However, this device does not have a structure suitable for wire ropes of different lengths. When testing wire ropes, if some wire ropes are too short, the clamping components at both ends are too far apart to clamp both ends of the wire rope, and if the wire rope is too long, both ends of the wire rope will droop outside, thus affecting the measurement.

[0005] In view of the above problems, it is urgent to innovate and design on the basis of the original structure of the wire rope dynamometer for bridge detection. Content of the Utility Model

The reverse movement of the two sets of threaded connectors drives the clamping seats at both ends to stretch the wire rope, so that it is in a straight state, which is convenient for tensile testing. By adjusting the position of the two sets of clamping seats, it can adapt to wire rope workpieces of different lengths, increasing the application range of the test;

[0017] 3. Test structure. When the wire rope workpiece needs to be tested for tension, the hook on the upper end of the dynamometer body is hung at the midpoint of the wire rope workpiece, and then the electric telescopic rod is operated.
