In construction and engineering projects, excavators are important representatives of heavy machinery and equipment, and their safe operation is directly related to the life safety of workers and the smooth progress of projects. According to the 2023 Machinery Industry Production Safety Accident Analysis Report, there were 310 production safety accidents in the machinery industry, killing 294 people, among which mechanical injuries, object strikes and falls from heights were the most common types of accidents. This article will comprehensively explore the key aspects of excavator work safety, including safety hazard identification, preventive measures and necessary training requirements, to help relevant practitioners establish safety awareness and reduce accident risks.

Common safety hazards in excavator operation

As a large-scale construction machinery, there are many safety hazards in the operation of excavators. Understanding these potential risks is the first step to prevent accidents. The following are several aspects that need to be focused on:

Risk of boom operation: The boom of the excavator is one of the parts that are most likely to cause personal injury. When operating an excavator, in order to prevent workers from being hit by the boom, the operator should rotate the boom at a safe speed. In addition, the blind spot of the boom is also an important risk point. The operator’s line of sight may not cover all working areas, increasing the risk of collision.

Mechanical injury risk: According to accident statistics in 2023, mechanical injuries account for the highest proportion of accidents in the machinery industry. The crawler, hydraulic system and other moving parts of the excavator may cause injuries such as squeezing and entrapment. Especially when repairing or inspecting equipment, the risk will be greatly increased if the energy is not properly locked or the dangerous parts are not isolated.

Rollover and stability issues: There is a risk of rollover when the excavator is operating on uneven ground, slopes or soft soil. Such accidents usually have serious consequences and may cause the operator to be trapped or seriously injured. Improper load distribution and overloading operations also increase the possibility of rollover.

Electrical and underground facility hazards: Excavators may come into contact with underground or overhead cables during work, causing electric shock accidents. According to accident statistics, electric shock is the fourth type of accident in the machinery industry, and it is particularly necessary to be vigilant in excavator operation.

Risks in auxiliary operations: Equipment inspection and maintenance operations are the link with the highest accident rate in the auxiliary production process. This is mainly due to the nature of temporary operations, the lack of fixed safety processes, and insufficient hazardous energy control measures. In the process of excavator maintenance, related risks need special attention.

Identifying and understanding these safety hazards is the basis for developing effective safety measures. Only by fully recognizing the potential risks can targeted prevention and training be carried out to reduce the accident rate.
