Performance Feature
1. Under-Bridge Access Platform
The Truss-Type Bridge Inspection Vehicle features an articulated truss or folding arm that extends horizontally beneath the bridge deck, providing a stable working platform for inspectors. The platform can be adjusted to reach different bridge depths and clearances, accommodating various superstructure types.
2. Stable Multi-Axle Chassis
Built on a multi-axle heavy-duty truck chassis, the vehicle provides stable road handling during transit and a firm working base during deployment. Outriggers level and stabilize the machine on uneven approaches.
3. Precision Positioning
Hydraulic controls allow smooth, precise movement of the platform along the bridge length and depth. Operators can position the platform within centimeters of inspection targets, ensuring safe and efficient access to girders, bearings, and cable stays.
4. Safety and Compliance
The platform includes guardrails, fall arrest anchors, and emergency egress options. All lifting and positioning systems meet EN and OSHA-equivalent safety standards, with overload protection and fail-safe braking on all hydraulic movements.

View DetailsWhy Choose Yutong Truss-Type Bridge Inspection Vehicle
Inspecting a bridge means getting a stable working platform under the deck — to examine girders, bearings, expansion joints and piers — without closing the whole carriageway. The Yutong truss-type bridge inspection vehicle mounts a horizontal truss platform on a multi-axle truck chassis that drives to the bridge, deploys outriggers, and lowers the working platform beneath the span so inspectors and non-destructive-testing equipment can access the underside safely.
Reach and stability define the machine. The truss platform extends horizontally beyond the bridge edge to a typical under-bridge working depth, giving a long, rigid walkway that several inspectors and tools can occupy at once. The multi-axle chassis keeps axle loads within road limits for highway transit and rapid relocation between bridges, while the outrigger system locks the chassis for stable platform work even in wind.
Yutong supplies the truss platform together with the truck chassis as one factory-tested system, so hydraulic reach, control logic and safety interlocks are calibrated together. The range covers 20 m to 26 m class truss units plus cable-stayed and upgraded configurations, letting you match the machine to the bridges in your inspection programme.
How to Choose the Right Product
Choose truss reach to your bridge spans
Measure the maximum under-bridge working depth and horizontal reach required by your bridge stock. Truss-type platforms reach a long, rigid walkway suited to box girders and T-beams where you need continuous underside access. A 20 m class unit suits smaller overpasses; a 26 m class suits wider highway and railway bridges. Match reach to your largest bridge, not the average.
Truss platform versus folding-arm (bucket) design
A truss platform gives a long, stable, wide walkway for two or more inspectors and light repair work across a span. A folding articulating arm reaches under tight constraints and around obstacles but carries fewer people. Choose the truss type when your work is systematic inspection and light maintenance across a long deck; choose a folding-arm unit when access space under the bridge is the limiting factor.
Spec for wind, traffic control and NDT load
Operation is wind-limited; specify on-board anemometry and auto-locking. Plan traffic control — lane closure and signs — around the outrigger footprint. If inspectors carry ultrasonic, photographic or sampling equipment, confirm platform capacity and tool mounts before purchase.
Common Applications
Highway bridge periodic inspection
Routine inspection of motorway and arterial overpasses — girder, bearing and expansion-joint checks from a continuous truss platform.
Railway and metro overpass inspection
Under-rail inspection where the platform must deploy without track possessions, using rapid setup and lane-side access.
Bridge maintenance and repair access
Sealing joints, cleaning drains and applying protective coatings from the underside working platform.
Cable-stayed and special bridge access
Specialised configurations with extended reach to access stay cables, pylons and under-deck structures.
Post-disaster and damage assessment
Rapid deployment after floods, earthquakes or impact to assess bridge substructure and pier condition.
Export Compliance & After-Sales Support
Each bridge inspection vehicle is delivered with road-going chassis certification, hydraulic and safety-system documentation, and English operator and maintenance manuals. Outrigger load, platform capacity and stabilisation data are supplied for your road authority and insurance. Yutong's export rights cover the whole mounted system.
Standard warranty is 12 months. Hydraulic, structural and platform wear parts are quoted as kits, and the export engineering team responds within 48 hours on reach, stabilisation or training questions. Send your bridge span table and access conditions to market@yutonggroup.com and we will recommend the truss class.
Frequently Asked Questions
What under-bridge reach do the truss units provide?
The range covers 20 m to 26 m class truss platforms, with horizontal reach and working depth suited to most highway and railway bridges. Match the class to your largest span.
Truss platform or folding arm — which do I need?
Truss gives a long, stable walkway for multi-inspector systematic work; folding arm reaches tight or obstructed under-bridge spaces with fewer people. Tell us your bridge geometry and we will advise.
How long does deployment take?
Typical setup is around 15 to 30 minutes: position, deploy outriggers, lower the platform. Repositioning along the span is then straightforward.
What wind limits apply?
Operation is typically limited below about 13.8 m/s with on-board anemometer monitoring and automatic platform locking in high wind.
What work can be done from the platform?
Visual and NDT inspection, crack measurement, bearing checks, concrete sampling, plus light maintenance such as joint sealing and drain cleaning.
Is training included?
Yes. Yutong provides operator training on delivery covering platform operation, safety interlocks, emergency procedures and traffic-control planning.
Do you export and support after sale?
Yes — over 60 countries, with 12-month warranty, hydraulic and structural spare-parts kits and 48-hour technical response.
