  Variable speed and forward and backward When shifting into gear, first push the throttle handle forward to the low-speed idling position, and then push the main clutch lever to the forefront to separate the main clutch. Due to the action of the small brake in the main clutch, the power input shaft of the transmission stops rotating . At this time, you can correctly move the shift lever to the required gear, and then put the forward or retreat lever to the forward or backward position. After the gear is engaged, pull the throttle handle backward to increase the engine speed, and connect the main clutch smoothly, and the bulldozer starts to drive. When the  Bulldozer  is driving, the main clutch control lever should be pulled to the rearmost position, not in the semi-engaged position. Because the half-engagement of the main clutch will aggravate the friction lining wear. Bulldozer transmissions generally have 5 forward gears and 4 reverse gears. The advance and retreat rod can be used

  As an important construction machinery equipment, bulldozers need to be properly maintained in the daily work process, which can not only improve the production efficiency of the equipment but also extend its service life and create more value for customers. Below we will tell you three common knowledge about   Crawler Bulldozer   maintenance. The bulldozer track maintains proper tension Maintenance method of the bulldozer: If the tension is excessive, the spring tension of the guide wheel acts on the track pin and the pin sleeve. The outer circle of the pin and the inner circle of the pin sleeve have been subjected to high compression stress, and the pin and the pin sleeve will wear prematurely during operation. The elastic force of the guide wheel tensioning spring also acts on the guide wheel shaft and the bushing, resulting in a large surface contact stress, which makes the guide wheel bushing easy to grind into a semicircle, the track pitch is easy to elongate, and it will reduc

  The   Bulldozer   driver is very important to the daily maintenance of the bulldozer to ensure the safe and effective use of the bulldozer, prevent malfunctions and accidents, and extend the service life of the bulldozer. Your bulldozer is always out of order, so what do you use to make money? So, in order to earn more money, you must do the following ten points: 1. In order to prolong the service life, the car should be stopped when the gear is changed or reversed. 2. Do not perform steering operation under load. 3. When the  Track Type Dozer  is doing the bulldozing operation, the cutting soil is too deep or the rear part is tilted, and the cutting depth should be adjusted in time to keep the bulldozer evenly bulldozing. 4. When the load is large, use a lower speed for operation. Bulldozer 5. Always be in control during exercise. 6. Choose the appropriate gear when going downhill and don't change gear when going downhill. 7. Lift the blade to a proper height before starting, ab

  During the work of crawler bulldozers, the following safety items should be paid attention to: 1. Check whether the fuel filling point of the  Crawler Bulldozer  is full. Fill the water tank when the water is insufficient. Check the fuel level and when filling the fuel, fireworks are strictly prohibited. 2. Whether the joysticks are normal and in the neutral position, depending on the surroundings, there are no safety hazards. 3. Start the engine at idle speed, check the technical status of the machine, and remove the fault in time if the fault is found, and work only when the oil temperature and water temperature rise to the specified values. 4. When the traction machinery is connected, the lowest reverse gear should be used. 5. It is not allowed to refuel, add water, or adjust the work during driving. During driving, random personnel are not allowed to lean on the door or stand on the wing panel, and they are not allowed to get up and down the bulldozer when it is not stopped. Hydr
