The 25th National \"Safety Production Month\" in 2026: Everyone talks about safety, everyone knows how to handle emergencies; identifying and addressing potential risks and hazards. -------------------------------------------------- 2. How should one deal with the situation where the driving wheels of coke oven vehicles deviate from their track? Answer: When 1 to 2 of the vehicle’s driving wheels deviate from the track, several steel plates of various thicknesses, measuring 200–300 mm in length and 70–120 mm in width, need to be prepared. These plates should be laid in the direction opposite to that in which the wheels have deviated, starting from the bottom of the driving surface of the affected wheels and progressing from thinner to thicker plates, with them being placed closely against the track. The installation should continue until the elevation of the last plate is at the same level as or slightly above the track surface (usually at a distance of about 1 meter). Once this is done, the vehicle can be slowly moved in the direction opposite to that of the wheel deviation; thanks to the cushioning effect provided by these plates, the driving wheels will naturally return to the correct track position. When 2 to 4 of the vehicle’s driving wheels deviate from their track, the overall driving resistance becomes very high due to the large number of such wheels; even with steel plates laid as a transition, the vehicle may still be unable to move. In such cases, it is necessary to prepare 2 jacks of 50t or 100t each, along with several steel plates. These jacks should be placed under the steel structure of the trolley on which the wheels that have deviated from the track are located, in order to lift them up and raise the lower edge of the wheels above the track surface. After that, steel plates should be laid beneath those wheels, pressing them firmly in the direction opposite to the direction of travel (usually at a distance of about 1m). Once the jacks are released, the same procedure should be followed for the remaining wheels that have deviated from the track. After using a jack to lift the track back onto the traveling wheel that has fallen off its track, drive in the direction opposite to that in which the wheel fell off, and it will be possible to get the vehicle back on track.
