Question 61 RVR04 - Master or Mate of LT 200 GRT

The Correct Answer is D **Explanation for Option D (All of the above):** The primary responsibility of a crane operator is safety, which requires total situational awareness. The load, the hook, and the boom are the three critical components of the crane's operations that pose the greatest risk and determine clearance, stability, and trajectory. Therefore, the operator must continuously monitor the location and movement of the: * **Load (A):** To ensure it is clear of obstructions, is not overloading the crane, and is being set down safely. * **Hook (B):** As the interface between the crane and the load, monitoring the hook's position is essential for proper rigging and alignment. * **Boom (C):** The boom's angle, extension, and swing dictate the working radius and overall stability of the crane, requiring constant attention to avoid two-blocking or contact with surrounding structures/power lines. Since awareness of all three (load, hook, and boom) is non-negotiable for safe and effective operation, "All of the above" is the correct answer. **Explanation of why other options are incorrect:** * **A) load:** While crucial, focusing *only* on the load neglects the position of the boom (which determines stability) and the hook (which connects the load to the boom). * **B) hook:** While essential for controlling the hoist/trolley, focusing *only* on the hook neglects the overall size and trajectory of the load and the position of the boom. * **C) boom:** While critical for stability and clearance, focusing *only* on the boom neglects the precise location and movement of the load being handled, which is the primary objective of the lift.
