There are usually two channels: go to the construction site to find an old master to study, and the other is to go to a regular excavator training school. It is rare to find an old master to learn at present. Usually it is because the family has something to do with the old master that they learn this way. The advantage of this situation is that they can be familiar with the environment and contacts of the construction site in advance, understand the world, technically face more emergencies, see how the master handles it and learn some practical experience. If you study in a training school, you will spend more time using machinery, because learning from the master at the construction site can't delay the progress of others' projects, and you can only touch the machinery occasionally during the break. There is no such thing as worldly wisdom. The school just pays tuition to teach you skills, which is relatively simple.
Learning excavator
If you are studying in a training school, usually two to three months is the time limit for a student to basically master excavator driving, which is about three months. Some students who learn quickly can master the basic operation within two months. However, if you are studying with an old master on the construction site, the time is not fixed, because it is not fixed to practice mechanically on the construction site, but it needs flexible arrangement, so the time required may be longer.
