Overhead Crane Practice Test 2025 – 400 Free Practice Questions to Pass the Exam

When "2-blocking" occurs in overhead crane operations, it refers to the situation where the hook block comes into contact with the top part of the hoist or any associated components during the lifting process. This situation can lead to significant mechanical issues. The crane may sustain physical damage due to the excessive stress placed on its components, such as the hoist mechanism and the supporting structure. This can create not only a risk of damage but also a considerable safety hazard for operators and nearby personnel, as it can disrupt normal operations and potentially lead to catastrophic failure.

While other options may describe various crane malfunctions or consequences, they do not capture the full scope of risks and damage associated with "2-blocking" as effectively as noting the potential for structural damage and safety hazards. Understanding "2-blocking" and its implications is essential for ensuring safe crane operation and minimizing risks on the worksite.
