Question: An older mobile crane, manufactured before 1980, is being used on a job site. According to provincial OHS regulations for cranes, which of the following is most likely to be a specific requirement for this older equipment regarding its safe operation that might differ from newer cranes?

Answer options: ✅ It must be equipped with an anti-two-block device.

• It must have a current load moment indicator (LMI).
• It must have a certified logbook detailing all previous lifts.
• It must be equipped with a swing brake.

Correct answer: It must be equipped with an anti-two-block device.

Explanation: Provincial OHS regulations often exempt cranes manufactured before a certain date (e.g., 1980) from requiring load moment indicators (LMIs). However, an anti-two-block device is a fundamental safety feature generally required regardless of age to prevent structural damage and hoist rope failure.
