What is the proper approach when lifting a heavy load with cribbing and pulleys?

• A. Use a properly rated pulley system, ensure all cribs are placed to bear the load, avoid binding, maintain communication, and monitor for movement.
• B. Use improvised, ungraded pulleys to speed up.
• C. Ignore crib placement to save time.
• D. Remove communication to simplify.

Answer: (A)

Safe lifting with cribbing and pulleys relies on using a properly rated system, placing the cribbing so it directly bears and distributes the load, avoiding any binding in the rope path, maintaining clear communication, and watching for movement throughout the lift. A properly rated pulley system ensures the hardware and rope can handle the load without failure, giving predictable performance under load. Cribbing must be arranged to create a stable, level base and to transfer the weight evenly across supports, so the structure doesn’t tilt, crush, or slip as the lift progresses. Avoiding binding is essential because a bound or tightly snared rope can cause jerky movements, high local stress, or sudden shifts that compromise the cribbing and the entire rig. Keeping communication open ensures everyone coordinates timing, observes changes, and can stop the lift if something starts to move unexpectedly. Monitoring for movement allows immediate checks for crib creep, shifting, or rope elongation, enabling a controlled, gradual lift or a safe lower if needed. Using improvised, ungraded pulleys, ignoring crib placement, or removing communication would drastically increase the risk of equipment failure, instability, and injury, which is why the best approach centers on rated gear, proper cribbing placement, clear coordination, and vigilant monitoring.
