Max.Operating Width 15m Arch Installation Trolley for Transportation Transportation Dimension L X W X H 11000×2800×4300mm

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. This equipment is designed specifically for high-altitude, low oxygen environments, and complex geological tunnel construction. It integrates mechanical, electro-hydraulic, and intelligent control technologies, making it ideal for arch installation operations in various engineering projects.

Adopting a folding arm structure consisting of a first stage arm, a second stage arm, and a third stage arm, this trolley provides 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 that enables automatic calibration of the arch frame posture.

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

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.

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.

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.

High synergy with the three-step method
