Top 10 Questions for Derrick Builder Interview

1. What is the difference between a single and double girder crane?

A single girder crane is a crane that has a single main beam, while a double girder crane has two main beams. The main beams are the horizontal beams that support the hoist and trolley. Single girder cranes are typically used for lighter loads, while double girder cranes are used for heavier loads.

2. What are the different types of hoists that can be used on a crane?

Wire rope hoists

• Wire rope hoists are the most common type of hoist used on cranes. They are durable and reliable, and can lift heavy loads.

Chain hoists

• Chain hoists are less common than wire rope hoists, but they are still used in some applications. They are lightweight and portable, and can be used to lift lighter loads.

3. What are the different types of trolleys that can be used on a crane?

There are two main types of trolleys that can be used on a crane: end trucks and bridge trolleys. End trucks are mounted on the ends of the main beams, while bridge trolleys are mounted on the bridge of the crane. End trucks are typically used for lighter loads, while bridge trolleys are used for heavier loads.

4. What are the different types of crane controls?

There are three main types of crane controls: pendant controls, radio controls, and cabin controls. Pendant controls are the most common type of control, and they are typically used for smaller cranes. Radio controls are used for larger cranes, and they allow the operator to control the crane from a distance. Cabin controls are used for the largest cranes, and they allow the operator to control the crane from a cabin that is mounted on the crane.

5. What are the different types of crane safety features?

There are many different types of crane safety features, including: overload protection, overspeed protection, and anti-collision systems. Overload protection prevents the crane from lifting loads that are too heavy for it. Overspeed protection prevents the crane from moving too fast. Anti-collision systems prevent the crane from colliding with other objects.

6. What are the different types of crane inspections?

There are two main types of crane inspections: daily inspections and annual inspections. Daily inspections are performed by the crane operator before each use of the crane. Annual inspections are performed by a qualified inspector once a year.

7. What are the different types of crane maintenance?

There are many different types of crane maintenance, including: preventive maintenance, corrective maintenance, and emergency maintenance. Preventive maintenance is performed on a regular basis to prevent problems from occurring. Corrective maintenance is performed to fix problems that have already occurred. Emergency maintenance is performed to fix problems that are critical and require immediate attention.

8. What are the different types of crane training?

There are many different types of crane training, including: operator training, inspector training, and maintenance training. Operator training is required for anyone who operates a crane. Inspector training is required for anyone who inspects cranes. Maintenance training is required for anyone who maintains cranes.

9. What are the different types of crane regulations?

There are many different types of crane regulations, including: OSHA regulations, ANSI regulations, and ASME regulations. OSHA regulations are enforced by the Occupational Safety and Health Administration. ANSI regulations are developed by the American National Standards Institute. ASME regulations are developed by the American Society of Mechanical Engineers.

10. What are the different types of crane certification?

There are many different types of crane certification, including: operator certification, inspector certification, and maintenance certification. Operator certification is required for anyone who operates a crane. Inspector certification is required for anyone who inspects cranes. Maintenance certification is required for anyone who maintains cranes.

As a Derrick Builder, your primary responsibility is to design, construct, and maintain derricks used in various industries, including oil and gas drilling, construction, and shipbuilding.
