About the 20m Truss-Type Bridge Inspection Vehicle for Cable-Stayed Bridges
Yutong developed the 20m for sustained bridge inspection duty: 20 m of under-bridge reach, the matched platform and a matched wheelbase keep the crew productive on the deck, while the matched rated power drives the boom and platform hydraulics without straining the carrier.
The boom, platform and tie-off points are built as one system and verified on the proving ground: stabiliser spread, axle loads and platform envelope are documented in the spec sheet, and the carrier is braced so the boom holds position without drift at full reach.
Selecting the 20m starts with the bridge inventory: span class, girder depth and access points decide the reach and platform size, and Yutong configures the carrier from those numbers, with spares and field support through the global network.

View DetailsEngineering & Application Notes
The 20m is specified with the road in mind: 20 m of under-bridge reach on a the matched wheelbase with a matched rated power, and the the matched platform keeps the crew position while axle loads stay inside the limits of the markets it is exported to. The 20m moves between structures without special escorts, which is the number procurement teams check against their own fleet rules.
Cable-stayed bridge package
Cable-stayed bridges need access under the deck between the cable anchorage zones, and the 20 m truss-type unit is configured for exactly that band. The platform works the pylon-foot and anchorage zones the suspension hardware occupies, and the carrier holds the rig steady in the wind loading a river crossing brings. Specialist inspection teams use this package with ultrasonic and laser mapping gear on the platform, so the rated payload margin and platform stability are part of the specification, not an option.
Frequently Asked Questions
What bridge clearance range can the 20m Truss-Type Bridge Inspection Vehicle for Cable-Stayed Bridges access?
The 20m Truss-Type Bridge Inspection Vehicle for Cable-Stayed Bridges 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.
