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.

2. Plateau adaptability design
Equipped with a high-altitude dedicated engine and hydraulic system, it can operate stably in low temperature and low oxygen environments above 3500 meters. The hydraulic system adopts low-temperature anticoagulant hydraulic oil and intelligent temperature control module to ensure smooth operation in extreme environments.

Features:

In the construction process of the three-step method, the tunnel is excavated in three stages: upper, middle, and lower. The KGM12200GS with its three folding arms can work independently at different levels:

• Step Up: The arm frame can reach the arch top and accurately position the arch frame.
• Middle and Lower Steps: The folding arm can be adjusted horizontally or diagonally to avoid interference from step slopes and facilitate the installation of side wall arches.

The equipment's operation rhythm aligns with the three-step excavation cycle:

• After upper step excavation, promptly install the arch frame.
• During middle and lower step work, synchronize the side wall support.
• While constructing the inverted arch, retract the arm frame to clear space and prevent equipment blockage.

The equipment collaborates with a self-propelled inverted arch wharf to facilitate support closure lining flow construction.

Three-step construction often faces challenges such as fractured surrounding rock or fault zones. To address this, the equipment is outfitted with:

• Rapid support capabilities to minimize surrounding rock exposure and control deformation.
• Advanced geological adaptation through integration with TSP, geological radar, and other prediction systems for tailored support strategies.
