About the 23m Truss-Type Bridge Inspection Vehicle
The 23m is a truss-type bridge inspection vehicle rated for 23 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 23m 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
For a bridge fleet, the 23m is chosen against the inventory: 23 m of under-bridge reach and the matched platform bring crews to girder and bearing zones, on a a matched wheelbase with the matched rated power. Inspectors work the 23m where span class and access points decide the reach number, and the carrier is specified so the unit reaches the deck position the crew needs without a second support truck.
Truss-type rig for deep truss bridges
Truss bridges put the inspection surface inside the truss plane, where ladders and gondolas struggle and access from the deck is blocked by the top chord. The 23 m truss-type unit takes the platform along the truss plane, so inspectors work the diagonals, gussets and lower chord on a stable stage instead of hanging off ladders. Owners of long truss spans specify this reach class for the main river crossings, and the platform tie-off layout follows the anchor points the truss geometry allows.
Frequently Asked Questions
What bridge clearance range can the 23m Truss-Type Bridge Inspection Vehicle access?
The 23m 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.
Does Yutong export to my country?
