Which equipment combines the under-bridge capability of a snooper truck and the freedom of movement of platform rigging?

• A. Rigging
• B. Underbridge Inspection Vehicle
• C. Platform Equipped Underbridge Crane
• D. Shadow Vehicle

Answer: (C)

Access to the underside of a bridge while still being able to move around the structure requires equipment that can both reach under the span and reposition itself as work progresses. A snooper truck or under-bridge inspection vehicle provides reach under the bridge, but its mobility is limited to where the base vehicle can travel and it often lacks the lifting capability needed for handling tools or components. A platform by itself offers mobility but doesn’t provide a dedicated mechanism to lift and position equipment under the bridge. The Platform Equipped Underbridge Crane integrates a mobile platform with a crane or hoist for under-bridge work, giving you both the ability to access the underside and the freedom to move and operate around the structure efficiently. The shadow vehicle serves mainly as support and does not deliver these specific capabilities.
