Massachusetts Hoisting License Practice Test

What does two lights or bells signify?

1. Lower

2. Stop

3. Raise

4. Lower slowly

The correct answer is: Raise

Two lights or bells are commonly used in hoisting operations to communicate specific signals to the operator, signaling that it is safe to raise the load. This type of signaling is essential in ensuring the safe and efficient operation of cranes and hoisting equipment, as effective communication is key to preventing accidents or mishaps on the job site. In many hoisting operations, a single light or bell may indicate one action, while the presence of two typically denotes a more urgent or definitive action—in this case, raising. Understanding these signals is crucial for operators to implement the correct responses in alignment with established protocols and safety standards. While other signals exist for different operations, such as stopping or lowering, interpreting two lights or bells as a command to raise is standard practice, making it clear that this is the correct understanding in the context of the question.
