Product Description:
Potential/Potency KGM12300 Arch Frame Trolley is the first arch frame trolley in China with the ability to erect multiple arches at once.
1. Engineering chassis, four-wheel drive, four-wheel steering.
2. Three working arm frame, the main arm is a folding+telescopic structure.
3. Each of the left and right arms is equipped with a work platform, which is equipped with an arch dragging and clamping device.
4. The main arm has a multifunctional platform that can simultaneously clamp 1-4 arches and quickly lift them into place to assist in operations.
5. Controller control, large screen display of parameters, real-time monitoring of system operation status.
Features:
1. Engineering chassis, four-wheel drive, strong climbing ability; Four wheel steering with a small turning radius; More suitable for tunnel construction.
2. The main arm is a folding and telescopic structure, which can be folded back to the frame as a whole during transportation and driving, and can also be equipped with multiple arches for transporting unit A; At the same time, it can adapt to the step construction method and cross step operations;
3. The tray of the main arm of the equipment has the function of transporting multiple arches, and the maximum adjustment distance between the arch clamping mechanism of the main arm tray and the inside and outside is 2400mm (an arch with a spacing of 800 can support 4 arches at a time). The arch spacing can automatically adapt according to the spacing of the arches. The tray has multiple degrees of freedom, making it easy to install and adjust the arch.
4. The auxiliary arm platform is equipped with an arch dragging device, which allows the main arm to stand on the step arch while also standing on the middle step arch during three step construction; Assist the main arm in erecting arches on both sides during half section or full section work. Moreover, the towing device can tow the arches from any position on the ground to the platform (with low requirements for stacking the arches on both sides); Because the steel wire rope is flexible, it is more convenient for the docking and bolt connection between the arches.
5. The linkage mechanism at the end of the main arm, in conjunction with the tray action, can independently install arches on the ground.
6. Through sensing devices and self memory functions, the tray can automatically adjust to the initial set leveling state, reducing manual adjustment time and difficulty.
7. Install an anti-collision warning system for the boom, monitor the coordinates of the boom in real time, and implement warnings for critical collisions of the boom. Ensure multi arm equipment, flexible and collaborative safe operation over a wide range.
Install an overload warning and protection system for the boom, monitor the load distribution at the end of the boom in real time, and provide equipment overload warning reminders to ensure safe operation of the equipment.
8. Intelligent fault analysis and diagnosis system; Monitor and record the operating status of the equipment through various types of sensing devices on the device. When the device malfunctions, it can intelligently diagnose the problem or troubleshoot through remote human-machine interaction mode.
9. Through advanced electro-hydraulic control technology, the equipment has better maneuverability, smooth movement, and very little end shaking.

Applications:
1. High security:
A. The number of construction personnel required for the product has been greatly reduced, with only 2-3 operators and 2-3 construction personnel.
B. After the equipment reaches the palm surface, the main arm operator is located under the supported surface and uses remote control to lift the multi arch forming frame of Unit A, which is transported by the equipment, to the installation position. Due to the prefabrication of multiple formed arches, including horizontal bars and mesh, it is equivalent to supporting an umbrella shaped protective net at the tunnel arch top;
C. Due to the use of a drag clamping device in the auxiliary arm, the arch frame of Unit B can be placed under the already supported surface, and the construction personnel can hang it. The operator can remotely operate it to lift and position the arch frame of Unit B; All operations can be completed under the supported surface;
D. When the construction personnel on the auxiliary arm platform are connecting bolts and welding horizontal bars and mesh, there are already multiple formed arches supporting the arch crown; All construction personnel were not exposed to exposed rock surfaces, thus greatly improving safety.
2. High economic efficiency:
A. Due to different construction techniques and environments, the equipment can save an average of 1-2 hours per work cycle. Calculated based on one work cycle per day, 15-30 days can be saved per year, greatly improving the efficiency of arch erection operations;
B. The equipment only requires a minimum of 3 people and no more than 6 people for operation and construction work. Depending on the surrounding rock conditions and arch size, 5-9 people can be saved, which can save a lot of labor costs annually;
C. The equipment only needs to divide the entire arch frame into three sections, and reduce the number of connecting nodes by 2-6 for each arch frame according to different working conditions, saving the number of connecting plates and bolts, thereby saving material costs;
D. At the same time, the equipment has good mobility and can accommodate both palm faces, which can save more construction personnel.
3. High adaptability:
A. According to different construction methods, it can adapt to the construction requirements of single arch, multiple arch frames, including multiple double arch frames and folding arch frames;
B. Able to adapt to tunnel construction with different cross-sectional sizes; It can meet the construction requirements of large section tunnels such as high-speed rail double track tunnels and four lane highways, as well as small section tunnels such as flat guide tunnels, transverse tunnels, and inclined shafts;
C. It can adapt to the construction requirements of various construction methods such as full section, half section, micro step, and three step tunnels.
4. Multifunctionality (auxiliary functions):
A. The equipment has three arms and three platforms, and the main arm platform can be expanded to meet the installation function of explosive cartridges after drilling holes with the rock drilling rig (this function needs to be optional);
B. The maximum lifting height of the equipment is 12 meters, and the platform can carry more than one ton. It can be used as an aerial work vehicle for the installation and auxiliary operations of tunnel facilities;
C. The hoisting mechanism of the auxiliary arm towing and clamping device can be used as a truck mounted crane for lifting, installing, and other lifting operations of the inverted arch.
