When Tower Crane Inspections Become Vital

By Aimee Schwartz


Cranes are crucial equipment for projects that need hauling and moving of materials of big sizes and heavy weights. In constructions sites, materials such as concretes and steel bars are lifted by cranes. Having tower crane inspections in Tennessee conducted by qualified technicians is important since it helps in promoting safety when running these machines. A collaborative approach is needed when using cranes because of the kind of work they handle and the hazards presented.

Operators, workers, inspectors, and owners of cranes all have a duty to play to promote safety. While operators should observe safety standards, inspectors have to be competent in their work. A crane operator should be highly trained and certified to operate such machines. These operators obtain their certification from trusted schools.

The company inspecting cranes should also have modern equipment used in the inspections. It may be done on monthly or even yearly basis. But this is depended on other factors including what manufacturers have recommended. Other standards as set by bodies such as the ASME/ANSI may apply. Cranes owners need to make sure that they only hire operators who have go through intensive training and have been certified.

In addition to pre-shift examinations, there are the detailed professional checkups. These are done by certified inspectors. The inspectors examine the mechanical functioning of cranes and bring out any issues of concern that need attention. They survey the ground to see if it is in good form. They also look at how workers are conducting themselves when cranes are being operated.

Accidents can occur when cranes are improperly operated. Most accidents reported in crane zones are caused by instability, overloading, unstable grounds, and contact with electricity. Cranes are mounted on stable grounds. Before the machines are mounted, ground testing is done to ensure the surfaces are firm to support the machines. Also, during operations, the stability of cranes is checked to avert accidents.

A small fault such as a loose nut or bolt could trigger a catastrophic accident. When operators examine these small issues, they prevent accidents. Professional inspectors are called in time in time to do comprehensive examinations. During the time inspectors are undertaking their training, they are taken through the operating mechanics of cranes and how to identify hazards.

A pre-shift inspection can help bring out issues that may pose potential dangers in using cranes. If operators run the cranes with defective parts and components, it increases the chances of causing accidents. Similarly, if inspections are not done at the right time and by the right personnel, it also presents risks of hazards.

Pre-shift inspections help check on things like twisted wire ropes, worn out slings, loose nuts and bolts, the hydraulic system, as well as the presence of rust or corrosion. Operators prepare reports that may be used by certified professional inspectors when conducting their inspections. Periodic inspections are conducted by certified people who are trained on how to handle the task.
