Abstrakt

The brake linkage of a hoisting machine is a very important component determining the safety of

the hoisting machine’s entire braking system. It is subject to weekly inspections. However, an efficiency

test of brake performance is carried out every 6 months. Once every 3 years, a test must be carried out by

an appraiser who pays particular attention to the executive and control components of the brakes as well

as the strain - brake system and brake release components. The legal provisions regulating the testing

of braking system linkages are not precise. So far, the control has been based on random measurement

of strains using electrical resistance strain gauges stuck to the surface of the linkage. A new method

for measuring the strains of the linkage has been proposed in the work. It is based on fibre optic strain

sensors with Fibre Bragg Gratings (FBG). They are mounted using specially designed and tested holders

for mounting on the brake linkage. They provide quick assembly and the measurement of strain in the

direction parallel to the axis of the linkage. The structure of the holder also allows for the measurement

in 4 positions turned every 90 relative to one another. Such a measurement enables a comprehensive

analysis of strains and stresses in the brake linkage. In the work, it was shown that there is a complex

state of strain and stress in the brake linkage. The previous procedures for linkage testing are inadequate

in relation to this condition. An experimental and numerical method was proposed to assess the state

of linkage stress. It should constitute the basis for the decision of the appraiser to allow the linkage for

further use. The method proposed in the work also allows for continuous measurements of linkage strains

as well as dynamic braking tests.
