How do you quickly reset a bulldozer after track derailment?


When the operator finds the track derailment, he should stop immediately and take necessary reset measures according to the degree of derailment and environmental conditions. Do not reset by force, otherwise it will cause bending and deformation of guide wheel and rear axle and damage the front beam, final drive and rear axle shell and other parts.


1: Slight derailment means no derailment of guide wheel and drive wheel. If only the supporting pulley comes out, use a sledgehammer to knock the track inwards a few times to make the track back on the supporting pulley. If the supporting wheel is taken off slightly, you can slowly drive the locomotive back and forth for a few times to reset, but you should be especially careful when operating, and it is better to have someone under the car to direct the operation to avoid serious derailment.


2: General derailment single guide wheel or drive wheel derailment, loosen the track tension adjusting nut, take out a track plate pin from the back of drive wheel to make the track release freely, then restore the detached track to normal position and install the track plate pin. After unilateral derailment, it is forbidden to force forward or backward, otherwise it will cause more serious derailment or damage the walking device.


3: Unilateral big derailment unilateral supporting wheel, guide wheel, drive wheel, belt wheel all derailment, then loosen the track tension adjustment nut to make the track loose, then take out a track plate pin from behind the drive wheel, disconnect the track, lift up the locomotive with a jack, set up the track under the supporting wheel, then remove the jack and connect the track.


4: When bilateral derailleur and bilateral tracks all fall off, start from the side with more serious derailleur and reset separately. The method of resetting is the same as the handling method of single big derailment.
