High Light tunnel arch assembly machinearch installation trolley with 2000kg capacity7.5 outer arch assembly machine

Product Description:

KGM12200GS Plateau Type Three Folding Arm Arch Frame Trolley

The KGM12200GS plateau type three folding arm arch frame trolley is a high-performance specialized equipment developed by Changsha Keda Intelligent Equipment Co., Ltd. This trolley is designed for use in high-altitude, low oxygen environment, and complex geological tunnel construction projects. It integrates mechanical, electro-hydraulic, and intelligent control technologies, making it suitable for arch installation operations in railway, highway, water conservancy tunnels, and other engineering projects, especially those requiring the three-step method.

Three Level Folding Arm Structure Design

The trolley features a folding arm structure consisting of a first stage arm, a second stage arm, and a third stage arm. The arms are linked by hydraulic cylinders, providing a wide range of deployment and high flexibility. This design allows for multi-angle and multi-posture arch positioning in narrow spaces.

Plateau Adaptability Design

Equipped with a high-altitude dedicated engine and hydraulic system, the trolley can operate stably in low temperature and low oxygen environments above 3500 meters. The hydraulic system uses low-temperature anticoagulant hydraulic oil and intelligent temperature control module to ensure smooth operation in extreme conditions.

Intelligent Control System

The trolley features an integrated PID control algorithm and real-time feedback of boom posture through tilt sensors. The control system adopts an electronic control handle and a user-friendly interface, supporting manual, semi-automatic, and fully automatic modes to reduce operational difficulty and labor intensity.

Security Protection System

Equipped with a patented protective shield descent system, the trolley can quickly deploy the shield and activate the descent device in case of rockfall, ensuring safe evacuation. It also features arm collision warning, overload protection, and attitude limit safeguards for enhanced security.

 

Features:

Adapt to multi-stage segmented construction
In the construction of the three-step method, the tunnel is excavated in three steps: upper, middle, and lower. The three folding arms of KGM12200GS can operate independently at different step heights:

Step up: After the arm frame is deployed, it can reach the arch top and accurately locate the arch frame;

Middle and lower steps: The folding arm can be adjusted horizontally or diagonally to avoid interference from step slopes and achieve installation of side wall arches.

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

High synergy with the three-step method
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.

Ability to deal with adverse geological conditions
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.

Applications:

The KGM12200GS plateau type three folding arm arch trolley is designed to meet the efficiency, accuracy, and safety needs of three-step construction. This is achieved through its intelligent control system, multi-level arm flexibility, and specific plateau design.

Specifically engineered for complex projects like western plateau tunnels and railway deep buried tunnels, this trolley has been successfully utilized in various national key tunnel projects. It has quickly become a benchmark product for enhancing the mechanization level of tunnel construction.
