Crane Operator Certification Exam Prep · Question
A crane operator is reviewing a critical lift plan for hoisting a 15,000 kg precast concrete panel. The plan specifies an initial lift with a dynamic factor of 1.25. If the panel's weight is 15,000 kg, what is the 'effective' weight that the crane and rigging must be capable of handling during this initial phase?
The dynamic factor accounts for additional forces during the initial lifting, acceleration, and deceleration of the load. The effective weight is calculated by

Question: A crane operator is reviewing a critical lift plan for hoisting a 15,000 kg precast concrete panel. The plan specifies an initial lift with a dynamic factor of 1.25. If the panel's weight is 15,000 kg, what is the 'effective' weight that the crane and rigging must be capable of handling during this initial phase?
Answer options:
- 15,000 kg ✅ 18,750 kg
- 12,000 kg
- 30,000 kg
Correct answer: 18,750 kg
Explanation: The dynamic factor accounts for additional forces during the initial lifting, acceleration, and deceleration of the load. The effective weight is calculated by multiplying the actual load weight by the dynamic factor: 15,000 kg * 1.25 = 18,750 kg. This effective weight is used to ensure the crane and rigging are adequately sized to handle transient forces.
