The LG312K The intelligent arch integrated trolley, LG312K, is a marvel of modern engineering, seamlessly integrating a multitude of vital processes such as surveying, setting out, under-excavation operations, arch installation, mesh and connecting bar welding (optional), and explosive charging. This cutting-edge machine is capable of completing an entire excavation and arch installation in one go without needing to be relocated. Built on a robust engineering chassis, it features a dual power system of diesel and electric, complemented by a short wheelbase, compact body, enhanced flexibility, and superior traction. These attributes make it exceptionally suited for a variety of complex tunnel pavement conditions. The boom is operated via both wireless remote control and manual control, ensuring smooth and precise movements. This innovative design guarantees safety, rapid operation, high efficiency, and energy conservation.
Expandable Man Basket: The LG312K is equipped with an expandable man basket, providing a spacious operating environment capable of accommodating 3-6 personnel. This feature is ideal for tasks such as loading explosives and anchoring rods, thereby enhancing operational convenience and safety.
High Efficiency: Featuring a three-arm structure with three grippers and three hanging baskets, the LG312K is adaptable to full sections, two-step, three-step, and other construction methodologies. Remarkably, all vertical frame construction processes can be completed within approximately one hour, significantly boosting productivity.
Installation of Precast Arch: Utilizing our company's independently developed and patented multi-frame precast arch technology (Patent No. ZL202022537953.5), the LG312K reduces both the work duration and construction risks associated with dangerous working faces, thereby substantially enhancing construction efficiency.
Reduction of Number of Operators: With the LG312K, the entire construction operation can be efficiently handled by just 3-4 operators, a significant reduction from the traditional requirement of 8 or more personnel. This automation and efficiency translate to cost savings and minimized labor requirements.
Auxiliary Function Integration: The LG312K comes equipped with a breaking hammer, enabling immediate under-excavation operations post-arch installation. This integration of auxiliary functions streamlines the construction process, ensuring uninterrupted workflow and increased productivity.
Small Overall Dimensions: Designed with a lightweight and compact structure, the LG312K is perfectly suited for small-section construction conditions, making it a versatile tool in various tunneling environments.
Equipment Informatization (Optional): The LG312K supports a comprehensive array of informatization features, including cluster management, positioning function, video monitoring, interphone functionality, pre-alarm system, data management, tunnel BIM technology, digital twin, construction report management, tunnel contour scanning, and remote control. These advanced capabilities ensure effective management and monitoring of construction projects.
