How to Use the Crawler Bulldozer Not Easy to Malfunction?

Mar. 19, 2020

Today Bulldozer China Factory introduces the correct way to use the crawler bulldozer.

1.Speed change and retreat

When shifting gears, the throttle handle should be pushed forward to the low-speed idling position, and then the main clutch lever should be pushed to the front to disengage the main clutch. Due to the small brake in the main clutch, the power input shaft of the transmission stops rotating. . At this time, you can correctly shift the shifting benchmark to the required gear, and then put the forward and backward lever to the forward or backward position (when the bulldozer is forward, pull the forward and backward lever back, and push it forward when back). After being in gear, pull the throttle handle backwards to increase the engine speed, and connect the main clutch smoothly, and the bulldozer starts running.

When the bulldozer is driving, the main clutch lever should be pulled to the rear, not in the semi-engaged position. Because the main clutch is half-engaged, friction plate wear will be aggravated. Bulldozer transmissions generally have five forward gears and four reverse gears. The forward and backward lever can be used to change the direction of the bulldozer.

When the bulldozer is operating, it should run at the highest speed as possible to improve the operating efficiency. However, the driver should always pay attention to whether the engine is running normally. When the engine is overheated and the exhaust smoke is found, the speed should be appropriately reduced.

2. Steer

When the Crawler Dozer is turning, the steering clutch lever on the steering side can be pulled back to disengage the steering clutch, so the track speed of the corresponding side becomes slower, and the bulldozer starts to turn. In order to make the bulldozer make a sharp turn, in addition to disengaging the steering clutch, the corresponding brake pedal should be depressed. Generally, the sharp turn is allowed only when the first gear is running. When the brake is not used, the foot should not be placed on the brake pedal, otherwise it will cause wear of the brake belt and increase fuel consumption.

When the bulldozer is turning, step on the brake pedal smoothly to avoid jumping when turning. After turning, release the brake pedal and release the joystick. If the turning radius is large, it is not necessary to step on the brake pedal. When you don’t want to, don’t make the bulldozer turn in place at high speed, so as to avoid the accident caused by the track derailment.

3. Drive on the ramp

Different types of bulldozers have different climbing capabilities (generally 30 °), and the slopes and terrains that can be adapted by bulldozers of the same structure are also different. The driver should be familiar with the climbing limits of the model used to avoid landslides due to insufficient uphill and downhill capabilities.

Before going uphill, you should choose the appropriate speed gear according to the terrain, slope size and length, and you are not allowed to change gears during climbing. When going uphill, the bulldozer should run at a perpendicular angle to the hillside, and no horizontal driving is allowed on steep slopes; the blade can be lowered appropriately to avoid affecting sight, and in the event of a landslide, the blade can be quickly grounded to help the bulldozer Brake; if the engine stops on the way uphill, the fuel supply should be stopped immediately, the blade should be lowered and the brake should be applied immediately. If you cannot stop on the slope, you should change the reverse gear and slowly slide to the bottom of the slope (while braking and sliding), and then start the ground to persuade; if you do not stop the fuel supply and slide down in the forward gear, it will be transmitted to the back due to power. The engine caused a reverse fire, causing the air cleaner to inject fuel. In case of reverse fire, close the throttle quickly and brake the bulldozer. Before restarting, check that the shift lever is in the neutral position. When the bulldozer goes downhill, the low speed and small throttle position should be selected, and the brake pedal should be used.

The above are several ways to use the tracked Dozer, which can effectively avoid failures.
