Max.Operating Width 15m Arch Installation Cart The Ultimate Tool for Streamlined Transportation

Product Description:

The 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.

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.

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:

The equipment can quickly move between steps and operate in parallel with excavation and slag removal processes, reducing the construction period.

By using tilt sensors and PID control (patented technology), real-time compensation is provided for arch tilt caused by uneven excavation surfaces, ensuring that arch installation meets design parameters (horizontal error ≤± 1 °, vertical error ≤± 0.5 °).

Avoiding manual measurement errors and significantly improving the quality of initial support.

The traditional three-step construction requires frequent installation of scaffolding or temporary platforms, while the KGM12200GS can be flexibly positioned through the boom and directly operated at high altitude, reducing auxiliary processes.

Operators only need 1-2 people (traditional methods require 6-8 people), reducing safety risks and labor costs.

Match the equipment operation rhythm with the three-step excavation cycle:

• After excavating the upper steps, quickly install the arch frame;
• When following up on the middle and lower steps, synchronize the side wall support;
• During the construction phase of the inverted arch, the arm frame is retracted to make way for space and avoid equipment occupation.

Support joint operation with self-propelled inverted arch wharf to achieve support closure lining flow construction.

Three-step construction often encounters fractured surrounding rock or fault zones, and the equipment is equipped with:

• Rapid support capability: Shorten the exposure time of surrounding rock and control deformation;
• Advanced geological adaptation: It can be linked with TSP, geological radar, and other prediction systems to adjust support strategies.

Technical Parameters:

Applications:

The KGM12200GS plateau type three folding arm arch trolley is designed to meet the efficiency, accuracy, and safety standards needed for three-step construction. This is achieved through its intelligent control system, multi-level arm flexibility, and plateau-specific design. The trolley is especially well-suited for complex projects like western plateau tunnels and railway deep-buried tunnels.

With successful applications in various national key tunnel projects, this device has been recognized as a benchmark product for advancing tunnel mechanization construction. Its features make it an ideal choice for enhancing the level of efficiency and safety in tunnel construction projects.
