What are the common problems that occur with lifting devices and how do you avoid them?

Common problems with lifting devices include mechanical failure, overloading, improper use, and lack of maintenance. To avoid these issues, ensure regular inspections and maintenance, follow the manufacturer's guidelines for weight limits, and train operators on proper use. Additionally, implement safety protocols, such as load testing and visual inspections before each use, and consider using lifting devices with safety features like overload protection and limit switches.
