In relation to mobile cranes, what is a 'counterweight'?

A counterweight in the context of mobile cranes is a weight that is added to enhance the crane's stability. It serves to counterbalance the load being lifted, particularly when the crane is working with loads that are offset from the center of rotation. The purpose of the counterweight is to ensure that the crane does not tip over by maintaining balance while operating. Properly placing and sizing the counterweight is crucial for safe operation, as it allows the crane to handle its rated load without exceeding stability limits.

This aspect of crane operation is fundamental in preventing accidents and ensuring that loads are lifted safely. When cranes operate with loads that create significant leverage against the crane's base, the counterweight compensates for this by providing additional downward force on the opposite side, thereby stabilizing the entire structure.
