Ladder type fiberglass bridge is a special form of FRP bridge with a trapezoidal or stepped structure. It is usually used in situations where cables need to span different heights or need to be routed along slopes.

Ladder type FRP bridge has the following features and advantages:

1. Strong adaptability: It can adapt to the needs of different height differences or slope wiring, and can be flexibly used in various scenarios.

2. High strength: Made of fiberglass material, it has excellent strength and stiffness and can withstand a certain load and pressure.

3. Corrosion resistance: FRP material has good corrosion resistance and is suitable for humid and corrosive environments.

4. Light weight and high strength: light weight, high strength, easy to transport and install, and has high load-bearing capacity.

5. Easy to install: reasonable design, easy to install, can quickly connect the bridge and realize wiring across or along the slope.

Installing a ladder type FRP tray usually requires the following steps:

1. Measurement planning: Measure the position and height difference across or along the slope according to actual needs to determine the installation location.

2. Install the bracket: Install the bracket to support the ladder bridge to ensure stability and safety.

3. Connect the bridge: Connect the ladder-type FRP bridge with other bridges to ensure that the connection is firm.

4. Adjust the angle: Adjust the angle of the ladder bridge as needed to make it meet the design requirements.

5. Inspection and debugging: Carry out inspection and debugging after installation is completed to ensure the safety and reliability of the bridge.

Ladder-type FRP bridges are commonly used in industries such as power, communications, and pipelines. They are used to span different heights or route along slopes during the wiring process to maintain the continuity and integrity of the wiring.
