reversed, however, and then will result after another 10 seconds a new half cycle. The cycle counter shall be a help for the maintenance team to get a better idea about the working life of various wearing items such as trolley traversing rope, hoisting rope, rope carriers, drive pulley lining, etc. . It is necessary that with the exchange of these items are always read at the cycle counter the resp. working cycles and that the results will be registered. As an additional maintenance help a lubricants tank is mounted to the traversing winch for lubrication of the crab traversing rope (please refer also to chapter General Maintenance Instructions ) . Traversing Limit Switches and Position Indicators As mentioned in the previous chapter the position indicator and the traversing limit switch (a screwt)pe limit switch) are arranged on the shaft of the return pulley, from which they can both be separated by a magic tooth coupling. With erection the traversing limit switch is set in a way, that the crab stops travel 130m before reaching the machine side, or resp. 110m before the counter side. The position indicator should then show the corresponding value. During operation the crab is automatically braked down electrically to v = 0 m/s, when one of the two end positions is reached. On the remaining track rope length travel is then only possible, when the bypass button is depressed. By depressing the bypass button the travel speed is also limited to v 20% of v rated. Running in opposite direction within Ns nange, there is no speed limitation. In order to ensure principally a reduction of the crab speed, the plant has been equipped with two additional stationary monitoring limit switches. These are arranged on always the first and the last rope carrier. As these are in parallel connection with the screwtype limit switch, they also cause a reduction of the crab traversing speed to v = 0 m/s by electrical breaking. To continue the travel to the end of the track rope is only possible by depressing the bypass button. The crab traversing is finally stopped electrically by each one limit switch at the end of the track rope. For being capable on principle to take into consideration further obstacles in the travel area, the screwtype limit switch has been equipped with further contacts. By the unavoidable slip between return pulley and crab traversing rope, and by the retensioning of the crab traversing rope, a correction of the screwtype limit switch and the position indicator will bee necessary. This correction should be made at least once a day with start of the new shift. For thi。
