About the 26m Upgraded Truss-Type Bridge Inspection Vehicle
The 26m is a truss-type bridge inspection vehicle rated for 26 m of under-bridge reach, with the the matched platform on a a matched wheelbase and the matched rated power, so boom, platform and stabilisers work as one system at full extension.
The working platform and rails are engineered for bridge crews: handrail and tie-off heights follow inspection practice, the platform brings operators to girder and bearing zones, and the carrier layout keeps axle loads inside road limits. Every unit is factory tested with the boom extended to its rated reach before delivery.
Choosing the right 26m variant comes down to span width, access points and how many metres of deck the crew needs to cover per shift. Yutong's engineering team works from your bridge inventory to confirm the reach and platform size, and the global service network covers spares, training and technical support.

View DetailsEngineering & Application Notes
On long viaducts and river crossings, the 26m decides inspection throughput: 26 m of reach covers the span band, the the matched platform and a matched wheelbase keep the unit stable, and the matched rated power drives the boom without drift. The 26m keeps the crew productive across a full bridge day, and the reach number is what the tender compares against the structure list.
Upgraded 4-axle carrier for long spans
The upgraded 4-axle 26 m version exists for the owner who wants one unit to cover both the long main spans and the heavy approach structures. Four axles spread the platform and boom loads so the carrier keeps road-legal axle loading with the full counterweight aboard, and the 26 m reach band clears the deepest girder sections in the inventory. Agencies on this spec typically run it on the trunk route all year and rotate it to secondary bridges when the trunk is in maintenance.
Frequently Asked Questions
What bridge clearance range can the 26m Upgraded Truss-Type Bridge Inspection Vehicle access?
The 26m Upgraded Truss-Type Bridge Inspection Vehicle provides under-bridge access typically ranging from 2 to 8 meters below the deck, with horizontal reach of 18 to 26 meters depending on the model. This covers the majority of highway overpasses and railway bridges in service.
What tasks can be performed from the platform?
The platform supports visual inspection, ultrasonic testing, crack measurement, bearing inspection, concrete sampling, and light maintenance work such as sealing joints and cleaning drainage systems. It can also accommodate small tools and non-destructive testing equipment.
How long does deployment take?
Setup time typically takes 15-30 minutes, including positioning the truck, deploying outriggers, and extending the platform. The vehicle can then be repositioned along the bridge length as needed for comprehensive inspection coverage.
Is the platform suitable for cable-stayed bridges?
Yes, specialized configurations are available for cable-stayed and arch bridges. These models feature extended reach and flexible articulation to access stay cables, pylons, and under-deck structures that standard platforms cannot reach.
What are the wind speed limitations?
Operation is typically limited to wind speeds below 13.8 m/s (Beaufort 7). The platform includes anemometer monitoring and automatic locking to secure the platform in high wind conditions.
What training is required to operate this vehicle?
Operators should hold appropriate commercial driver's licenses and complete manufacturer-specific training on the platform operation, safety procedures, and emergency protocols. Yutong provides on-site training with each vehicle delivery.
