Crane Accidents

OSHA 1910.179B(6) states that
only designated personnel shall be permitted to operate a crane covered by this section.
Designated means selected or assigned by the employer or employer’s representative as being qualified to perform specific duties. ASME B30.2-3.1.1 states that
cranes can only be operated by qualified personnel.
The biggest questions I hear from customers is, what is qualified personnel? ASME is very broad with its definition of personnel and makes it hard to decipher the ASME regulation. However if you read further into the ASME codes it gives you its definition of qualified personnel. If you refer back to ASME B30.2-0.2 it states that
a qualified person is a person who, by possession of a recognized degree in an applicable field or a certificate of professional standing, or who by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve or resolve problems relating to the subject matter and work.
So basically this is just telling you that to be a qualified personnel you need to be properly trained and have the experience, and show that you are fully capable of operating a crane. Training is the key to operating the crane properly. Just because somebody has operated a crane for 10 or 15 years it does not make them qualified. They need the knowledge to go with the skill. Even the experienced operator can learn from a training course. Many accidents occur because the crane operator regardless of his experience has little knowledge of the fundamentals of crane operation. I have posted a few crane accidents that look as if the operation of the equipment was improper. This video shows the dangers of picking up a load and using the crane as a securing device. Cranes are designed to pick loads straight up and down only. They not meant to pull sideways. This is what can happen when you side pull a crane or shock load it. Both cases were done here. This next video is of a rubber tired gantry crane that crashed. I am unsure of the cause whether was an operator error or if this was a equipment failure. If anyone knows about any of these accident please let me know and I will update the post.
