The basic operation of an excavator is as follows:
1. Confirm that there are no obstacles around the excavator, just like learning to drive, first observe the surrounding vehicle conditions;
2. After boarding, honking the horn serves as a warning to pedestrians and also serves as a safety warning;
3. Confirm that there are no alarms on the instrument panel and that there are no abnormal situations in the vehicle;
4. Turn the shut-off valve to ON to start;
The specific operation is divided into four actions: boom, jib, bucket, rotation, and some small machines also have a push shovel.
The hydraulic cylinder of the excavator is equipped with a buffer device inside, which can gradually release back pressure near the end of the stroke; If the piston is subjected to an impact load after reaching the end of the stroke, it will directly touch the cylinder head or bottom, which is prone to accidents. Therefore, it is advisable to leave as much clearance as possible when reaching the end of the stroke.
Jinan excavator rental manufacturers remind that using the excavator's rotation action to perform soil pushing operations will cause abnormal force on the bucket and working device, causing distortion or weld cracking, and even pin breakage. This operation should be avoided as much as possible.
Using the weight of the excavator body to excavate can cause abnormal stress on the slewing bearing, as well as strong vibration and impact on the chassis. Therefore, the use of hydraulic cylinders or hydraulic pipelines can cause significant damage.
When loading and unloading heavy materials such as rocks, excavators should approach the bottom of the truck compartment for unloading, or load soil first and then rocks. High altitude unloading is prohibited to reduce impact damage to the truck.
When a tracked excavator is deeply immersed in the mud, a wooden board is placed under the bucket, and the bottom end of the bucket is used to support the track. Then, a wooden board is placed under the track to drive the machine out.
These are all basic operations that can be memorized in about an hour. The main thing is that the chain action requires long-term practice and gradually becomes familiar. To learn the excavator well, one must have patience. For more related matters, come to our website http://www.ycgjglcl.com consulting service
