An excavator is an essential heavy equipment at construction site. The operators must be skillful to run excavator. Talking about the used excavator, it needs to be maintained properly. The experienced operators should be able to master the skills mentioned below.
It is necessary to determine the surrounding environment. While turning around the machine, the operators should be aware of the barrier and the landform to insure safety. In advance of moving the excavating machine, operators need to inspect the direction of the tracks in case of crashing and tip-over. In order to enhance the stability of the entire equipment, the left and right tracks should contact the ground completely. While the angle between bucket and boom is 90 degrees, the excavating force achieve the highest. And while the angle between the ground and bucket is 30 degrees, the earthmoving resistance is the lowest. Professional operators should be capable of controlling the bucket and boom to improve the excavating efficiency.
It will damage the performance of excavator while using bucket to dig rocks and the operator should try to avoid such situation. However, while it is essential to use excavator to accomplish the task, the excavating task should depend on the crack direction of the rocks. And the rocks should be broken before excavating. While the excavator is driven to flat the ground, the machine should be located at level surface. And the operators should keep the coordination between boom and bucket rod. It is of crucial importance to control the speed. While the machine is used to load the dumper, it should be kept at level surface. Otherwise, it will be hard to control the loading and delay the project. The distance between the dumper and excavator should be proper in case of crashing. And the height of the dumper should be lower than the position of excavator. Thereby, the time to rise the boom can be reduced.
While the used excavator is operated to fill the dumper, it is recommended to feed soil and little rocks first, and then the large rocks can be poured into the dumper. Thereby, the property of the dumper can be protected. While the machine is operated in the areas with soft oil, it is necessary to inspect the hardness of the ground. And while the machine is operated in water, the operators have to determine the depth of the water.
