Performance Feature
1. Under-Bridge Access Platform
The Bridge Inspection Platform 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 DetailsFrequently Asked Questions
What bridge clearance range can the Bridge Inspection Platform access?
The Bridge Inspection Platform 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?
