Description

Earthworking machine and method for operating an earthworking machine Technical Field The invention relates to an earth working machine (earth working machine) according to the preamble of claim 1, comprising a carrier comprising a movable undercarriage, in particular comprising a crawler-type undercarriage, a working device designed to perform earth or stone working, in particular to remove earth or rock, or to introduce a structure into the earth, and at least one steel cable which is at least temporarily subjected to tensile forces and which is adjustable in the longitudinal cable direction by means of a cable drive. The present invention relates to a method for operating an earth working machine according to the preamble of claim 12, which earth working machine comprises a carrier comprising a movable undercarriage, in particular comprising a crawler-type undercarriage, a working device by means of which earth or stone work, in particular removal of earth or rock, or introduction of a structure into the earth, and at least one steel cable which is at least temporarily subjected to tensile forces and which is adjusted in the longitudinal cable direction by means of a cable drive. Background Conventional earth working machines have been in use for a long time, particularly as construction machines, such as earth boring or underground diaphragm wall machines. Such earth-working machines typically use a plurality of steel cables to actuate the machine components. For example, in earth boring machines, a so-called main cable is arranged which comprises a main cable winch, by means of which a boring tool, in particular a kelly, can be lifted up and lowered down a mast. Furthermore, so-called feed cables can also be used, by means of which, for example, the drill drive slide can be adjusted along the mast by means of a feed winch. As a result, additional feed forces can be exerted on the drilling tool, for example. In addition, other steel cables, for example so-called auxiliary cables, which can take over additional lifting or towing functions by means of auxiliary cable winches, can also be arranged on such earth moving machines. Such a steel cable on an earth working machine has the advantage that a high pulling force can be applied to a machine part, e.g. a work tool, by means of a drive member, e.g. a cable winch, which is arranged at a distance from the machine part. The path of the steel cable may be predetermined by one or more deflection rollers (deflection roller). In addition, the steel cable can be wound on the winch drum in a very compact manner, so that different working lengths can be provided for transmitting forces in an efficient manner. Such steel cables are formed from a plurality of so-called cables, in particular wound axially. In this case, a plurality of cables may be combined into a stranded wire, wherein the steel cable itself may be composed of a plurality of such stranded wires. Thus, a high strength and flexible cable can be formed. In earth working machines, in particular construction machines, the steel cables are subjected to considerable wear. In this case, the wear depends inter alia on the duration of use, the forces exerted on the cable, the type and number of winding processes and environmental and weather conditions, which may be extreme, especially in outdoor construction sites. This wear can in particular lead to breakage of individual ones of the steel cables. The steel cable may lose more than a certain amount of its required strength and a certain number of cables in the steel cable break. In case of wear exceeding a certain level, a malfunction, i.e. a breakage of the steel cable, may occur during operation. The breakage of the steel cable during operation of the earth working machine may have serious consequences, namely not only excessive damage at the earth working machine itself or at nearby implements. But also for personnel on or in the area of the earth working machine there is a risk of life and limbs. Therefore, breakage of the steel cable on the earth working machine is avoided at all costs. It is known and routine to visually inspect steel cables used on earth working machines for broken cables on the surface at regular intervals and replace them after a predetermined number of operating hours. However, this approach also has drawbacks. First, if the number of operating hours before the replacement of the steel cable is set too low, the steel cable, which is still fully functional and unworn, is often replaced and discarded. This is economically inefficient as such cables can still be used further. In addition, if the earth working machine is used with high strength, especially in extreme weather conditions, it may be the case that cable wear occurs at an earlier point in time, and in such a case the predetermined time for replacing the cable is too late. In these rare but truly occurring situations, there is then likewise a risk of personal and mechanical
