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. 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:
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.
