Red Seal Mobile Crane Operator Practice Exam

Question: 1 / 400

Name one major component of a mobile crane.

Counterweight

The counterweight is a crucial component of a mobile crane, designed primarily to enhance stability and balance during operations. As the crane lifts loads, the counterweight works to counteract the moment created by the load on the boom, preventing the crane from tipping over. This is particularly important when dealing with heavy or unevenly distributed loads. The placement and size of the counterweight are carefully calculated based on the type of crane and the specific lifting requirements, ensuring that the crane can operate safely and effectively within its designated load limits.

While the chassis, which forms the base and support structure of the crane, is essential for mobility and stability, it is the counterweight that specifically addresses the dynamics of load lifting. Components like a transmitter or speedometer do not directly impact the crane's lifting capabilities or stability in the same manner that counterweights do.
