Causes Of Crane Accidents

Construction and the heavy equipment industry are a booming cornerstone of the world’s economy, employing millions across the world. These industries utilize some of the most powerful machinery ever developed to extract raw materials from the earth, transport them, process them, and bring it all together to create structures to ease society’s daily living.

However, due to the nature of the work being done, it also carries the greatest risk to damage structures, incur bodily harm, or even lead to fatal injury. To mitigate this, regulatory bodies such as OSHA have been established to create safety protocols and procedures to prevent harm to people and their surroundings.

Cranes, in all their varieties, are frequently used implements across several facets of these industries and are not exempt from causing potential harm. Let us have a deeper look at the causes of accidents and what can be done to make the worksite safer.

What Are the Most Common Types of Crane Accidents

Reasons behind crane accidents include:

  • The crane buckling or collapsing.
    Most cranes have support structures (such as stabilizers and outriggers) that prevent them from moving as they operate. If they are set up on unstable ground or surpass their weight limits during a hoisting operation, the crane is likely to tip over or collapse.
  • Improper assembly.
    Setting up the crane to properly operate is straightforward, but if done improperly, can cause accidents. Unnecessary extension of the boom without manufacturer manual reference or improper use of blocking supports are common aspects of improper crane assembly.
  • Improper/Insufficient employee training.
    Crane operators can ignore safety hazards if they are unaware of potential risks they could pose to their colleagues and nearby structures. Lack of, or unavailability of a signal person is also a safety risk. All workers on site should be aware of the crane’s operational range, and have some training on safety protocols, such as emergency hand signals.
  • Mechanical failure.
    This is often as a result of poor maintenance. The crane’s moving components wear out, which may cause them to malfunction and thus cause bodily harm or structural damage.
  • Electrocution
    This is most often encountered when an uninsulated part of the crane comes into contact with live electrical wires.

Ways to Prevent Crane Accidents

Proper care and attention is essential to prevent crane accidents. Most safety measures end up getting ignored in attempts to cut corners or to save on time and cost, ending up being more expensive and causing harm. Some preventative measures for crane accidents include:

  • Setting up the crane on safe, sturdy surfaces. This prevents the crane from buckling and possibly collapsing as it carries out operations.
  • Operating the crane well clear of live wires, with OSHA recommending a minimum 20-foot distance.
  • Carry out regular inspections. Inspections provide a clear image of the crane’s status, allowing for recommendations on repair and maintenance on worn and wearing components. Click here for a FREE overhead crane inspection form.
  • All staff working with the crane (operators, riggers, signal persons) should be qualified and competent/certified for their respective roles.
