When a hoist raises a load too high, what is likely to occur?

• A. Overloading
• B. Two-blocking
• C. Slipping
• D. Free-fall

Answer: (B)

When a hoist raises a load too high, the phenomenon known as two-blocking can occur. Two-blocking happens when the hook or block of the hoist comes into contact with the other block, such as the fixed block attached to the hoist, which can lead to serious operational issues. This situation can create an excessive force on the hoist, potentially causing structural damage or failure. It can also lead to the load becoming unstable or accidentally released, posing significant safety hazards to workers and equipment around the area. Understanding this concept reinforces the importance of adhering to load limits and operating guidelines for hoisting equipment. Proper training and awareness help prevent two-blocking and ensure safe lifting practices in the workplace.
