What measures do bulldozers pay attention to?
This information should be useful in use note 1. new machines should be used before running in the stage, do not directly put into use. In the "running in" process, special attention should be paid to lubrication and maintenance, as well as instrument inspection work, and found that the failure in a timely manner. 2. when the environment temperature is below 5 DEG C, cooling water should be heated to 80 DEG C, adding to the water tank, and a water discharge valve closed until the outflow, and then continue to fill. 3. diesel engine starting, it must be preheated without load operation, the oil temperature does not reach the scope of work, do not start driving. 4. in the process of starting from the neutral: do not directly to the second or third position, so as to avoid the bulldozer starting speed is too large, causing the transmission element to bear large impact load. Before the gear is released, do not pull the throttle lever to the maximum throttle position. The operating position of each control lever must be accurate, thorough and not stopped so as not to cause the clutch friction plate to slip and cause severe burns and wear. 5. in the process of speed change and advance and fall: when handling the shift lever, you should step on the accelerator pedal first, then pull the shift lever. If you pull from one gear to the desired gear, the car does not travel. It can be pulled from a position to neutral position, and then pulled to the required gear. If there is no special needs, we must not turn in situ at high speed so as not to cause severe wear or other damage to the walking system.
8. in the parking lot with the diesel engine flameout: to ensure safety, avoid accident, diesel engine before parking stall should be landing shovel. In 9. operations: push and shovel digging shovel in pushing or tillage operations, such as encounter greater resistance can not move forward, should immediately stop or shove scarificationoperation, must not be forced to work, should be taken to adjust the working device of bulldozer or back penetration amount and other measures. The bulldozer shovel or digging process, should avoid pulling the steering and brake lever, need to adjust the direction of bulldozer, bulldozer load should be reduced to a certain extent, and then pull the steering and brake lever. And when the crawler walking part and other parts is trapped between stones and other hard objects, should drive at low speed in opposite directions, excluding hard objects, re operation. Do not make the engine too long idle operation, to prevent the combustion chamber temperature is too low, the fuel can not be completely burned, causing carbon deposits, blocking the jet hole, stuck valve and other faults.
6., on steep slopes: Bulldozer slope line angle can not be greater than 30 degrees, the horizontal can not be greater than 25 degrees, in general circumstances should avoid large angle slope line, especially to avoid horizontal large angle slope. If it is necessary to travel on steep slopes, the driver shall undergo certain training or select experienced persons to prevent accidents. Bulldozer on steep slopes along the downhill, should choose a low gear should be placed in the small opening position on the engine throttle lever, and should pay attention to the total control of the brake pedal to prevent slipping. Bulldozers move on steep slopes, and if they need to turn during the downhill, the steering process can be the same as the steering procedure in general. But since the weight of the bulldozer itself can produce a downward trend on the steep slope, the entire course of the steering and braking lever should not be used too long. If a half of the stroke of the lever is manipulated, only one side of the steering clutch is separated, and the push is turned slowly on the opposite side under the influence of its own weight. This is the opposite of flat steering, operator attention. 7. travel on uneven roads or on wet ground: use low speed as much as possible to avoid emergency and frequent rotation. When running on a rock road, the tension of the track should be slightly tight, so as to reduce the wear of the track plate. The shovel and scarifier should not carry too high, generally from the ground 400mm. Over big obstacles, should be low. Avoid the greater obstruction of the ramp, and do not pull the steering and brake lever with the "split" side of the steering clutch as a cross over measure. When driving on a wet surface, bulldozers should not cause diesel fans to splash on the surface of the water.
