Transportation Dimension 11000×2800×4300mm Arch Installation Trolley for Large-Scale Installations

Product Description:

KGM12200GS Plateau Type Three Folding Arm Arch Frame Trolley is a high-performance specialized equipment developed by Changsha Keda Intelligent Equipment Co., Ltd. for high-altitude, low oxygen environment and complex geological tunnel construction. This device integrates mechanical, electro-hydraulic, and intelligent control, and is widely used for arch installation operations in railway, highway, water conservancy tunnels, and other engineering projects, especially suitable for the construction conditions of the three-step method.

1. Three Level Folding Arm Structure Design
Adopting a folding arm structure consisting of a first stage arm, a second stage arm, and a third stage arm, the arm frames are linked by hydraulic cylinders, providing a wide range of deployment and high flexibility. It can achieve multi angle and multi posture arch positioning in a narrow three-step space. The end of the arm frame is equipped with an automatic arch support adjustment device, which detects the horizontal and vertical angles of the arch frame in real time through high-precision inclination sensors, achieving automatic calibration of the arch frame posture.

3. Intelligent Control System
Integrated PID control algorithm, real-time feedback of boom posture through tilt sensors (installed on each stage of the boom), achieving dynamic self-balancing adjustment. The control system adopts an electronic control handle and a human-machine interaction interface, supporting three modes: manual, semi-automatic, and fully automatic, reducing operational difficulty and labor intensity.

4. Security Protection System
Equipped with a patented protective shield descent system, it can quickly deploy the protective shield and activate the descent device in case of sudden rockfall at the top of the tunnel, ensuring the safe evacuation of personnel. Equipped with multiple safety mechanisms such as arm collision warning, overload protection, and attitude limit.

Features:

Adapting to multi-stage segmented construction is essential for efficient tunnel construction. The three-step method involves excavating the tunnel in upper, middle, and lower stages. With the KGM12200GS, the folding arms can work independently at different heights:

• Step up: The arm can reach the arch top and position the frame accurately.
• Middle and lower steps: The arm can adjust horizontally or diagonally to avoid slope interference and install side wall arches.

This equipment can move between steps swiftly, operating parallel to excavation and slag removal processes, thus reducing construction time.

For precise control of arch posture, tilt sensors and PID control are employed to provide real-time compensation for tilt due to uneven excavation surfaces. This ensures that the arch installation adheres to design parameters, with minimal errors and improved quality of initial support.

For adverse geological conditions, the equipment possesses rapid support capabilities and advanced geological adaptation. This allows for better handling of fractured rock or fault zones, with the ability to link with prediction systems for adjusting support strategies accordingly.
