In construction engineering and earthwork, excavator as an indispensable heavy machinery equipment, its strong cross-country ability and flexibility has been widely used. However, with the increasing complexity of the operating environment of excavators, some potential safety hazards have gradually surfaced.

1. The door safety when going downhill and off the trailer

In the process of the excavator going downhill or down the trailer, the forward tilt of the fuselage causes the driver to habitously support the front windshield or door frame with his left hand and operate the walking rod with his right hand. This seemingly ordinary habit hides a huge security risk. If the door is unlocked and open, it will close quickly under the influence of gravity, and the impact is strong enough to crush or even cause serious injury.

2. Avoid raising your arms high when walking

In order to improve the vision or pursue the "cool" effect, some novice drivers lift the moving arm to the highest position when the excavator is walking, the bucket rod is fully expanded, and the bucket is facing up. This operation mode greatly increases the height of the center of gravity of the excavator, and once it meets the uneven road surface, it is prone to overturning accidents.

3. Precautions for driving on soft ground

When excavators work on soft ground such as marshes and river flats, if the ground bearing capacity is not assessed in advance, it is easy to fall into quagmire, resulting in equipment damage and even personnel safety accidents. Although the excavator adopts a crawler design, which increases the contact area with the ground, it still needs to be treated with caution.

As heavy machinery and equipment, the operation safety of excavator is directly related to the construction progress and personnel safety. By strengthening safety education, improving the awareness of operation standards, and taking scientific and reasonable preventive measures, we can effectively avoid the occurrence of the above safety risks, and ensure that the excavator works stably, efficiently and safely in a complex environment.
