Which is the most economical way to erect a large flat building?

• A. Use a tower crane
• B. Use a crawler crane
• C. Use a forklift and manual handling
• D. Use a mobile stringer crane

Answer: (D)

When erecting a large flat building, the cost is driven by how easily you can move equipment along the length of the structure while safely handling long steel members. A mobile stringer crane fits this well because it can travel along the building’s length on tracks, allowing lifts to progress as you go without repeatedly relocating heavy gear. This minimizes downtime, rigging work, and crew size compared to fixed or less mobile systems, and it avoids the high setup and foundation costs of a tower crane and the heavy, less flexible relocation needs of a crawler crane. Forklift and manual handling simply can’t safely or efficiently manage the weight and reach of large structural members. So, using a mobile stringer crane offers the best balance of mobility, capacity, and low setup costs for a long, flat-building erection.
