It is every operator’s nightmare: a poorly secured load that is lifted above the construction site and is about to fall out of the crane. You can imagine that if this happens, the hair on the operator’s neck will stand right up. The manner in which large and heavy loads are rigged is carefully chosen. As a result, not many accidents occur with such loads. However, less attention is paid to the manner in which small loads are rigged. In special cases a lifting plan is drawn up, which everyone will pay attention to.
More attention should be paid to loads consisting of, for instance:
Sometimes when a load is very light, it is difficult for the operator to keep it under control as the lifting block is heavier than the load. Such a load will also be more easily affected by the wind, making it prone to swerve.
It is especially these kinds of loads that are rigged by inexperienced people. It seems like simple lifting work, but it is not! Inexperienced and often uniformed people should therefore not be allowed to carry out such work. A permanent rigger at the construction site, so an employee who has received the proper training and is certified, may rig loads.
It is important that a load that has been rigged cannot simply fall from the crane.
