Product Description:
Given that mechanization of arch installation has become a trend in the current tunnel construction process, and there are products on the market that cannot be used or only achieve mechanization without improving work efficiency and significantly reducing construction personnel, they do not have true practical value.
Potential/Potency has developed this product by combining the advantages of the company's already produced multi arch support manipulator and multifunctional rock drilling machine. It can not only meet the requirements of improving work efficiency and reducing personnel, but also meet the ability of the entire process of tunnel arch erection operation. This product has currently applied for multiple invention patents.
Features:
Adopting engineering chassis, four-wheel drive, strong climbing ability; Four wheel steering with a small turning radius;
Adopting dual power of diesel and electric, diesel can complete walking and independently complete arch support;
Three working arm frame, arm frame form: folding+telescopic structure (upper arm+middle arm+lower arm, middle arm extendable); The transportation status can be folded and returned to the frame as a whole;
Dual work platform with arch dragging and clamping device on the platform; And the left arm has a crane function for accompanying the vehicle;
Dual hydraulic rock drilling mechanism, capable of providing drilling support for locking feet, advance and system anchor rods;
The main arm has a self transporting and forming multi arch device;
Equipped with an air-conditioned cab and a reversing camera;
Controller control, large screen display of parameters, real-time monitoring of system operation status;
The arm frame control intelligent assistance system can achieve rapid positioning of the arch frame and improve efficiency.

Applications:
Steel frame installation: The arch frame installation trolley is used for the installation of steel frames inside the tunnel. The steel frame is the skeleton of the tunnel structure, supporting the stability and safety of the tunnel. By using the installation trolley, the steel frame can be accurately positioned and quickly installed, improving work efficiency and installation accuracy.
Mesh installation: In addition to the steel frame, the arch installation trolley is also used to install mesh. Mesh is a part of tunnel lining used to disperse and absorb geostress, prevent rock loosening and collapse. The installation trolley can carry and fix the mesh, allowing it to be quickly and accurately installed in place.
Installation of connecting bars: Connecting bars are important connecting components between steel frames and mesh sheets, ensuring the integrity and stability of the entire supporting structure. The arch installation trolley can assist in the installation of connecting bars, ensuring that each connection point is firm and reliable.
Auxiliary inspection and risk mitigation: Safety inspection and risk mitigation are crucial during tunnel construction. The arch installation trolley is equipped with relevant equipment and tools, which can assist construction personnel in conducting safety inspections and risk mitigation work, timely discovering and handling potential hazards, and ensuring construction safety.
Underexcavation handling: Underexcavation may occur during tunnel excavation. The arch installation trolley can assist construction personnel in handling under excavation, ensuring that the cross-sectional dimensions of the tunnel meet the design requirements.
Explosive installation: The installation of explosives is a critical step in tunnel construction during blasting operations. The arch installation trolley is equipped with safety protection devices and operating platforms, which can assist construction personnel in safely and accurately installing explosives, ensuring the safety and effectiveness of blasting operations.
Anchor rod installation: Anchor rods are an important component of tunnel support, used to fix surrounding rock and prevent collapse. The arch installation trolley can carry anchor rods and installation equipment to assist construction personnel in installing anchor rods, improving construction efficiency and safety.
