Top 10 Questions for Overhead Worker Interview

1. What types of overhead cranes have you worked with?

In my previous roles, I have operated various types of overhead cranes, including:

• Single-girder bridge cranes
• Double-girder bridge cranes
• Jib cranes
• Gantry cranes
• Monorail cranes

2. What are the key safety considerations when operating an overhead crane?

Pre-Operation Checks:

• Inspecting the crane and its components for any damage or defects
• Ensuring the proper functioning of controls, brakes, and limit switches
• Verifying the load capacity and ensuring the load is within the safe operating range

During Operation:

• Maintaining a clear view of the load and surroundings
• Operating the crane smoothly and avoiding sudden movements
• Communicating effectively with ground personnel and other crane operators

3. How do you calculate the weight of a load?

To calculate the weight of a load, I use the following formula:

• Weight (lb) = Density (lb/cu ft) x Volume (cu ft)

I determine the density of the load material from reference tables or measurements. For irregular shapes, I may use methods like hydrostatic weighing or buoyancy to estimate the volume.

4. How do you ensure that the load is properly secured before lifting?

To ensure proper load securing before lifting, I adhere to these steps:

• Selecting the appropriate slings, straps, or other rigging equipment for the load’s weight and shape
• Inspecting the rigging equipment for any damage or defects
• Attaching the slings or straps to the load securely and evenly
• Ensuring that the load is balanced before lifting
• Testing the lift by gently raising the load a few inches to check its stability

5. What are the different types of load testing methods for overhead cranes?

• Static Load Testing: Involves applying a known load to the crane and observing its response under different conditions.
• Dynamic Load Testing: Simulates real-world load conditions by applying varying loads and movements to assess the crane’s performance.
• Proof Load Testing: Tests the crane to 125% of its rated capacity to verify its structural integrity.
• Acceptance Testing: Performed after crane installation to ensure it meets specified standards and operates as intended.

6. How do you troubleshoot common overhead crane issues?

When troubleshooting common overhead crane issues, I follow these steps:

• Identifying the symptoms of the issue and observing any error codes or alarms
• Consulting the crane’s technical manual or contacting the manufacturer for guidance
• Inspecting the crane’s components, including electrical connections, brakes, and limit switches
• Using diagnostic tools or software to identify the root cause of the issue
• Performing necessary repairs or adjustments to resolve the problem and restore the crane’s functionality

7. How do you maintain and inspect an overhead crane?

To maintain and inspect an overhead crane, I adhere to a regular schedule that includes:

• Visual inspections of the crane’s structure, components, and rigging equipment
• Lubricating moving parts and checking fluid levels
• Testing safety features such as brakes, limit switches, and overload protection systems
• Performing electrical checks to ensure proper functioning
• Documenting all inspections and maintenance activities for future reference

8. What are the best practices for working with multiple cranes on the same worksite?

• Establish clear communication channels and protocols for crane operators.
• Coordinate load movements and ensure proper sequencing to avoid collisions.
• Set up physical barriers or designated work zones to separate crane operations.
• Use visual signals, hand gestures, or radio communication for effective coordination.
• Conduct regular safety briefings and training for all personnel involved in crane operations.

9. How do you handle unexpected situations or emergencies while operating an overhead crane?

• Remain calm and assess the situation quickly.
• Immediately stop crane operations and secure the load.
• Notify relevant personnel, including supervisors and safety officers.
• Follow established emergency protocols and procedures.
• Cooperate with emergency responders and provide necessary information.

10. What measures can you take to minimize the risk of accidents and injuries when working with overhead cranes?

• Follow all safety regulations and guidelines.
• Wear appropriate personal protective equipment.
• Maintain proper clearances and avoid working under suspended loads.
• Inspect equipment regularly and report any defects or concerns.
• Receive proper training and certification for crane operation.
• Stay alert and be aware of surroundings.
• Communicate effectively with other personnel.
