As an indispensable and important equipment in modern engineering construction, the safe driving of excavators is not only related to the life safety of operators, but also directly affects the smooth progress and overall efficiency of the project. Therefore, mastering the safe driving skills of excavators is a compulsory course for every excavator driver. This paper will start with the precautions in the operation process, and put forward the following suggestions.

1. Proper use of armrests, tracks and pedals

Excavators are equipped with handrails outside the driving room, large and medium-sized excavators are also equipped with foot pedals, so when getting on and off, we must make good use of handrails, tracks, and foot pedals, do not jump directly from the machinery, jumping from high places is a kind of behavior that is harmful to the body, and the ground is often uneven on the construction site, there are also various stones and debris, which can easily lead to the imbalance of the human body and fall. The harm is great. It is best to regularly clean the grease and dirt on the armrests and pedals.

2. Strictly abide by the cab-driving regulations

Only one person is allowed to sit in the cab and other people are not allowed to ride together except the driver. The The driver can operate the seat after sitting on it and fastening the seat belt. If it is necessary to suspend the operation and communicate with the personnel under the vehicle during the excavation process, the safety rod should be lowered to prevent misoperation.

3.In the mining process, pay attention to maintain the smoothness of the machine

Do not dig the earth near the track to prevent the earth from collapsing and the machine tilting. If such an accident happens, it is necessary to support the body with the help of the bucket, adjust the track and the road shoulder to maintain a right Angle and then slowly retreat from danger. When working on the slope, the smoothness of the machine will also be greatly affected. You can first make a piece of ground on the slope, and let the machine sit on the ground before working. When loading earthwork and stones, this method can be referred to even if it is not on the slope. Building a platform with a suitable height can ensure the stability of the machine, and improve the loading efficiency and save fuel on the other hand. In addition, we should pay attention to the loading of the vehicle, do not let the bucket with soil and rock pass above the vehicle cab.

4. Precautions in the process of walking

Should inspect the driving route in advance, avoid the section of road that is not conducive to driving, if you need to pass a narrow space, it is best to have a guide to provide command signals.

The crawler excavator has a strong ability to travel on the dirt road, but because of its own weight, once it is trapped in the mud and swamp, it will become a difficult engineering accident to solve. Therefore, it is best to avoid the soft mud and swamp when it is not necessary.

Before climbing, it is necessary to consider whether the climbing ability of the excavator meets the requirements. The direction of forward and backward should be parallel to the direction of the maximum slope. If the slope is tilted up and down, it may lead to overturning.

5. Precautions for the use of accessories

In addition to the bucket, the breaker is also a commonly used accessory on the excavator. To operate equipment equipped with breakers, the operator must have a certificate of completion of technical training in driving construction vehicles (demolition purposes).Do not perform crushing operations at the end of the stroke. The operation of the crushing hammer at the end of the stroke of the hydraulic cylinder may cause damage to the hydraulic cylinder and the machinery. And do not put your foot on the operating pedal when you are not operating the breaker. Accidentally stepping on it will start the breaker and cause danger.
