The crawler excavator needs to be moved with a truck or trailer when changing the working environment. In the process of getting on and off the truck, many people are prone to accidents and losses without paying attention to the details. This article will summarize the operation skills and attentions of crawler excavator when getting on and off the truck for reference only.
1. operating skills of excavator getting on and off
1) When the excavator is getting on the truck, place the bottom of the bucket flat on the girder of the truck. When the boom is slowly lowered, slowly open the arm, and the bucket cannot slide back and forth on the truck. Raise the front end of the excavator, and then retract the arm to walk. Before walking, be sure to determine the front and rear positions of the idler. The excavator travels about one third of the whole chain plate. Then lift the boom and rotate it 180 degrees to the other end of the excavator, slowly lower the boom and slowly open the arm. Place the bucket flat on the ground, support the excavator to make it horizontal, and then walk the excavator. Before walking, be sure to determine the front and rear position of the idler. The excavator opens its forearm so that the excavator can fully walk on the truck. Retract the arm and bucket, lower the arm to the standard parking position, and complete the operation of getting on the excavator onto the truck.
2) When the excavator is getting off the truck, put the bottom of the bucket on the ground and open the forearm about 45 degrees. Before the excavator moves forward, the front and rear positions of the idler shall be determined, and the arm shall be retracted to one third of the chain plate. Slowly lift the boom and slowly retract the arm, so that the front track of the excavator slowly falls to the ground. Lift the boom and rotate it to the other end of the excavator, and put the bucket flat on the truck. Extend the arm and lower the arm. At the same time, the excavator walks to the ground, so that the crawler is separated from the truck, and the bucket cannot slide on the truck. Make the front track of the excavator fall to the ground smoothly. Complete the operation of getting off the excavator.
2. Attentions for excavator getting on and off the truck
1) When the excavator is getting on and off the truck, pay attention to the action coordination of the boom and arm. If the operation actions of boom and arm are not coordinated, it will cause the bucket to push the road and truck, and damage the truck and road. It will also cause instability when getting on and off the truck, and bring potential safety faults. It is required to be proficient in the operation skills of the excavator before the operation of the excavator on and off the truck.
2) When the excavator goes up and down the truck, if it drives the rotation, it is very easy to cause the chain plate to turn out of the truck and cause rollover. Thus causing excavator damage and casualties, attention must be paid during operation.
3) During the rotation of the excavator, carefully observe the surrounding environment and whether there are obstacles such as personnel and car. Be aware of the environment for the excavator to get on and off the truck, and do not smash, scratch or touch the truck safely.
4) Special attention must be paid to the walking of the excavator when getting on and off the truck. It must be carried out in cooperation with the retraction and release of the two arms of the boom. Otherwise, if the excavator is forced to walk only with the crawler, it will drag the bucket to scrape the surface of the truck and the ground. Pay special attention to the front and rear position of the idler before operation, so as to prevent the occurrence of safety accidents such as excavator falling.
