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.
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:
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
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.
