If the minimum crane counterweight clearance cannot be achieved, what must the crane team do?

When the minimum crane counterweight clearance cannot be achieved, erecting barricades around the crane is essential for ensuring safety. This action helps to create a physical barrier between the crane's movement and personnel in the vicinity, thereby mitigating the risk of accidents or injuries. By restricting access to the area, the crane team can help ensure that individuals do not inadvertently enter a space where they may be at risk of being struck by the crane or its counterweights.

Creating barricades is a proactive safety measure that protects workers from potential hazards associated with the crane's operation. It allows the crane team to conduct their work with reduced risk, contributing to a safer work environment.

The other options do not address the issue of minimum counterweight clearance as effectively as barricading does. Simply rotating the crane slowly and cautiously may not eliminate the risk of accidents, while sounding the horn or posting warning signs alone do not provide adequate physical protection from the crane’s movements.
