LANHI has introduced the Intelligent Arch Anchor Integrated Trolley, an advanced piece of equipment built on an engineering chassis. This trolley features a dual anchor system and comes with four-wheel steering, four-wheel drive, and bi-directional driving capabilities. It is equipped with a dual-power system that includes both electric and diesel options, allowing for electric-powered construction and diesel emergency operation. Its tri-arm remote control system makes it exceptionally versatile in various tunnel construction scenarios, particularly suitable for prefabricated arch installation and multiple bench construction methods.
The Intelligent Arch Anchor Integrated Trolley integrates several construction processes, including measurement and marking, under-excavation, arch installation, anchor net installation, pre-support, system anchor construction, and optional anchor grouting functions. The tri-arm, tri-gripper basket structure allows the central arm to lift up to 3 tons, enabling all frame erection processes to be completed within an hour.
This equipment incorporates LANHI's independently developed patented technology, offering two installation processes: multi-piece prefabricated arch and multi-piece prefabricated foldable arch. These arches are manufactured outside the tunnel, significantly reducing hazardous operation time and construction risks, thereby greatly improving construction efficiency. The maximum drilling depth of the equipment reaches 4.5 meters, and the left and right arm frames can simultaneously perform foot locking, system anchoring, and pre-support anchoring operations, further enhancing construction flexibility and efficiency.
Additionally, the Intelligent Arch Anchor Integrated Trolley is equipped with an expandable basket, providing more operating space for loading explosives and anchors. The optional grouting system allows for quick grouting operations after anchor installation. The entire set of equipment can be operated by only 3-4 people, whereas traditional methods typically require more than 8 people.
The equipment also includes a breaker and welder, allowing for under-excavation and welding operations during arch installation. The intelligent design features cluster management, positioning functions, video monitoring, intercom functions, warning/alarm functions, data management capabilities, as well as tunnel BIM technology and digital twin, construction report management, tunnel contour scanning, and remote control functions. The integration of these features greatly enhances construction safety, efficiency, and management levels, making LANHI's Intelligent Arch Anchor Integrated Trolley an ideal choice for modern tunnel construction.
