In most places where construction machinery is used, there are the most hidden dangers that may lead to major safety accidents. The main safety accidents caused by construction machinery are as follows:
Major Safety accidents involving vehicles and machinery:
The machinery overturns when it is traveling on the shoulder of the road or on a slope; accidents are caused by contact between the machinery and construction workers working around the machinery.
During a machine inspection, the frame (arm, etc.) pillar unexpectedly fell, causing someone to be caught in or trapped in a dangerous part of the machine. During transportation, the chain locking the bucket claw loosened and fell, injuring someone.
Overloaded vehicles or vehicles turning sharply (especially trailer-type vehicles) can cause rollovers. Accidents involving falling cargo and people due to improper loading methods or inexperienced operators. Major accidents involving boom cranes: Accidents involving mobile cranes, tower cranes, and other machinery where the hook and rope are not properly hooked to the cargo during operation can cause cargo to fall and hit people (a common occurrence on construction sites). Overloaded vehicles and small mobile cranes can also cause overturning and even fatalities due to operating with extended support legs.
When a truck crane is lifting cargo, a person may be trapped between the load and other objects. A person may become trapped between the machine (or its rear) and another object when in contact with the machine. A pile driver may overturn while moving on site. When the machine is rotating, a person may be knocked over by the rear of the machine, boom, frame, bucket, etc.
Major safety accidents involving vertical transportation machinery such as construction elevators and derricks:
Major accidents often occur due to incomplete or faulty safety guards, risky operations in strong winds, and failure to secure material doors. Workers may be crushed, trapped, electrocuted, or injured by overturned vehicles, flying debris, or malfunctioning machinery such as saws, cutters, benders, drills, welding machines, and loaders.
