| Structure: Hydraulic driven self-propelled mobile trestle, mainly composed of seven parts: front axle, main axle, rear axle, front bracket, rear bracket, walking drive device, and walking bracket. |  |
| Function: While carrying out construction under the bridge body, it can allow vehicles to pass through the filling layer through the trestle to reach the lower steps, perfectly matching the inverted arch (bottom plate) concrete construction under various excavation methods of the step method, achieving the construction requirements of early closure and early formation of the ring. | |
| Product advantages: 1. The span of the trestle bridge is large, which can meet the requirements of pouring inverted arch concrete in three working conditions: 12 meters, 24 meters, and 36 meters at once, greatly improving the speed of inverted arch construction. 2. The strength of the trestle is high, and it can safely pass through various construction vehicles weighing no more than 60 tons. 3. The space above the trestle is spacious, making it convenient for various construction vehicles to pass. Concrete tankers can easily pour concrete on both sides of the trestle, and excavators can also rotate on the trestle without obstacles, making it easy to clean up residual slag from the inverted arch. 4. All components of the trestle adopt hydraulic transmission, ensuring smooth operation and high reliability. |
