Dual Power Arch Installation Trolley Inner 3.0/Outer 7.5 Minimum Turning Radius for Precise 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.

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.

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:

1. 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.

2. Precise control of arch posture
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.

3. Reduce temporary support and manual intervention
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.

4. 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.

5. 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.
