Bridge Inspection: Efficient Access for Critical Infrastructure Assessment
The Anderson UnderBridge Solution
Anderson UnderBridge’s Hydra Platform equipment transforms bridge inspection operations by enabling:
Access bridge undersides in under 15 minutes, dramatically reducing lane closure duration compared to traditional methods.
Built-in power connections allow inspectors to plug in laptops, testing equipment, and electronic documentation tools without returning to their vehicles.
Platforms accommodate multiple inspectors simultaneously, providing 10-20 times more workspace than bucket trucks.
Equipment can move along the bridge while deployed, eliminating repetitive setup/takedown cycles.
Available air and water connections support cleaning operations when needed for proper inspection.
For complex bridge structures with extensive cross members or trust designs, Anderson UnderBridge’s articulated boom equipment ensures no bridge element remains inaccessible to inspection teams.
The Anderson UnderBridge Advantage for Inspections
Unlike regional competitors with aging equipment fleets, Anderson UnderBridge maintains the newest, most technologically advanced inspection platforms in the industry. Our equipment is designed to optimize the inspection process, with features like expanded platform space, built-in power, and rapid deployment systems.
Most engineering firms choose to rent equipment for inspection contracts, allowing them to avoid equipment maintenance, transportation logistics, and operator training requirements. Anderson UnderBridge’s rental program provides a practical solution that allows engineering firms to focus on their inspection expertise.

Articulated Boom Equipment
Approximately 15% of bridges with complex designs, such as truss structures or extensive cross members, require a unique approach and a different type of equipment. For these situations, Anderson UnderBridge offers articulated boom trucks. These versatile units provide the flexibility and maneuverability needed when other equipment solutions are not optimized for certain bridge structures or designs. Articulated boom equipment is:
- Ideal for bridges with significant vertical obstructions
- Capable of reaching between structural elements
- Perfect for high-wall applications requiring reach-over capabilities
- Available with industry-certified operators
Ideal for:
Suspension
