An industrial plant requires a crane to lift a new heavy-duty motor (8,500 kg or 18,740 lb) into a confined indoor space with a limited overhead clearance of 10 metres (33 ft). The access path is narrow, and floor loading capacity is a concern. Which factor presents the greatest challenge for this lift?

Question: An industrial plant requires a crane to lift a new heavy-duty motor (8,500 kg or 18,740 lb) into a confined indoor space with a limited overhead clearance of 10 metres (33 ft). The access path is narrow, and floor loading capacity is a concern. Which factor presents the greatest challenge for this lift?

Answer options:

• The need for specialized rigging gear for the motor.
• Coordinating the lift with ongoing plant operations. ✅ Restricted headroom and potential for contact with existing structures.
• Obtaining the manufacturer's lifting instructions for the motor.

Correct answer: Restricted headroom and potential for contact with existing structures.

Explanation: In a confined indoor space, restricted headroom and the proximity to existing structures pose the greatest challenge for crane operations. The limited space increases the risk of boom or load contact, requiring extremely precise crane operation and detailed pre-lift planning to avoid damage or incidents, as typically outlined in confined space lifting procedures.
