The LZG413A Step into the future of tunneling with the LZG413A Intelligent Integrated Drilling and Arch Trolley. This state-of-the-art machine is engineered to meet the demands of full-section tunnel construction and benching methods. Featuring a robust integrated frame engineering chassis and dual rock drilling arms, it ensures precision and efficiency. The standing arch frame boasts a dual-arm design, accompanied by three grippers and two expandable hanging baskets. With four-wheel steering, four-wheel drive, and bidirectional mobility, this trolley excels in electric construction and diesel-powered emergency scenarios. Its user-friendly interface, low failure rate, exceptional reliability, compact build, and easy maintenance make it an indispensable tool for modern construction.
Functional Integration: Experience unparalleled multi-functionality with our system, catering to tasks such as tunneling, anchor hole construction, arch frame installation, charging, anchor installation, anchor grouting (optional), and anchor net installation.
Wide Range of Applications: Our solution supports three-step, two-step, and full-section methods, adeptly fulfilling the rock drilling and arch construction requirements of diverse construction methodologies.
Convenient Operation: Featuring both a local console and remote operation capabilities, our system allows for high-angle views during rock drilling and close-range views during arch erection, ensuring optimal visibility and control.
Equipment Digitization (Optional): Unlock advanced functionalities with our optional digitization package, including cluster management, positioning, video surveillance, walkie-talkie, pre/alarm, data management, BIM technology, digital twin, construction reporting, tunnel contour scanning, remote control, and more.
Rock Drilling and Vertical Arching: Equipped with four operational arms-two double-triangular self-balancing rock drilling arms, two vertical arch arms-and three grippers, our system boasts a maximum arm support lifting force of 2.5 tons. This ensures seamless installation of prefabricated arch frames with precise positioning. Complete your construction process in approximately one hour.
Double Slip Structure: Our proprietary double-slip mechanism guarantees stable and rapid slippage, enhancing performance and reducing downtime.
Double Hanging Basket: Both the main and auxiliary vertical arch arms feature expandable hanging baskets, facilitating the installation of anchor rods and auxiliary charges post-drilling.
Grouting Function: The optional grouting system enables rapid grouting operations immediately after anchor construction, speeding up project timelines.
Auxiliary Functions: Our system is equipped with welding machines, power tools, and other essential equipment, significantly improving construction efficiency and productivity.
