Abstract:
The invention relates to a method for determining the replacement state of wear of a rope made of textile fibre material, wherein, during the use of the rope, the lengthening of the rope along the entire length thereof is monitored, and the rope is discarded when the lengthening of the rope along the entire length exceeds a defined maximum value (%). The method according to the invention is characterized in that the local lengthening of a discrete rope portion is also monitored, and the rope is discarded when the local lengthening of the rope portion exceeds a defined maximum value (%), wherein the maximum value of the local lengthening of the rope portion is greater than the maximum value of the lengthening of the rope along the entire length.
Abstract:
Wear sensor and the corresponding wear element, assembly and use. The sensor is intended for a wear element in a bucket of an earth moving machine. The sensor comprises a sensing electric circuit and at least one elongated arm (23) extending in a direction of detection defining a longitudinal axis. The arm (23) has a base (25) and an end. The end wears away together with the wear material of the wear element. The arm (23) comprises a plurality of electrical connections (27) forming part of the sensing electric circuit and extending different lengths with respect to one another, measured according to the longitudinal axis along the arm (23). The invention also relates to a wear element of a bucket of an earth moving machine, to an assembly and to the use thereof for determining the wear.
Abstract:
A method of measuring wear rate in an actual rubber tire. A section of rubber is cut out of an actual tire below the surface of the tire. The cut out section is attached to the surface of a first wheel. An abrasive substance is attached to the surface of a second wheel. The two wheels are rotated for a predetermined time, in opposite directions, in contact with each other, at uneven rates resulting in some slippage between the surfaces of the two wheels. The wear rate of the rubber tire is measured based on the changes in the cut section over time, in much less time and using less resources than required by conventional wear measurement methods.
