The LG312K The intelligent arch integrated trolley, LG312K, seamlessly combines multiple crucial processes such as surveying, setting out, under-excavation, arch installation, mesh and connecting bar welding (optional), and explosive charging. Capable of performing a one-time excavation and arch installation without any machine repositioning, this vehicle boasts an engineering chassis, a dual power system of diesel and electric, a compact wheelbase, and a highly maneuverable design. Its robust traction makes it ideal for intricate tunnel pavement conditions. The boom features both wireless remote control and manual operation, offering easy management, enhanced safety, rapid functionality, high efficiency, and energy savings.
Expandable Man Basket: This advanced equipment is equipped with an expandable man basket, providing a spacious operating area that can accommodate 3-6 people. It is particularly useful for loading explosives and anchor rods.
High Efficiency: With a three-arm structure, three grippers, and three hanging baskets, the LG312K supports various construction methods including full sections, two steps, and three steps. Remarkably, the vertical frame construction processes can be completed within approximately one hour.
Installation of Precast Arch: Our company employs an exclusive patent (No. ZL202022537953.5) for multi-frame precast arches. This innovation significantly reduces both the working duration and the risks associated with dangerous working faces, thereby greatly enhancing construction efficiency.
Reduction of Number of Operators: The entire construction operation can be efficiently managed by just 3-4 people, as opposed to the traditional requirement of 8 or more operators.
Auxiliary Function Integration: The equipment is integrated with a breaking hammer, enabling under-excavation operations immediately after arch installation.
Compact Overall Dimensions: Featuring a lightweight design with small overall dimensions, this vehicle is perfect for small section construction conditions.
Equipment Informatization (Optional): Supports an array of smart functionalities such as cluster management, positioning, video monitoring, interphone, pre-alarm, data management, tunnel BIM technology and digital twin, construction report management, tunnel contour scanning, and remote control.
