What term describes mobile inspection platforms or cages that ascend steel cables?

• A. Ladders
• B. Boom Lifts
• C. Climbers
• D. Scaffolds

Answer: (C)

Climbers describe mobile inspection platforms or cages that ascend steel cables. They’re used in bridge inspections to move along cable-guided routes or vertically up towers, providing a stable work surface while being pulled or elevated along the cable. This setup lets inspectors reach hard-to-access areas without assembling scaffolding or using a boom lift. Ladders aren’t platforms that travel up cables and sit on the ground minimally; boom lifts rely on a hydraulic arm rather than climbing a cable; scaffolds are temporary work surfaces that don’t ascend along cables.
