Specifically designed for large-scale pipe alignment and heavy-duty transport within tunnels, this AGV combines robust load-bearing capacity, precision navigation technology, and flexible control modes. It overcomes the challenges of heavy-load handling in the confined spaces of tunnel construction, making large-pipe alignment operations more efficient, safe, and intelligent.

I. Product Overview
This 30-ton heavy-duty AGV is an intelligent, trackless transport vehicle customized for tunnel construction environments. It integrates three core capabilities—laser SLAM navigation, wireless remote control, and omnidirectional heavy-duty drive—enabling the precise transport and millimeter-level alignment of 30-ton class large pipes in complex, narrow, and trackless tunnel environments. Widely used in the installation of water supply/drainage pipes, oil and gas pipelines, and TBM (Tunnel Boring Machine) auxiliary piping, it replaces traditional manual towing and rail-based transport methods, significantly enhancing automation and operational efficiency in tunnel construction.
II. Product Description
The vehicle features a high-strength welded platform chassis equipped with multiple sets of heavy-duty drive wheels, offering a rated load capacity of 30 tons. Its dimensions are optimized for tunnel access widths, and the platform surface utilizes an anti-slip grid design to ensure large pipes remain stable and secure during transport. It employs an advanced laser SLAM navigation system that eliminates the need for fixed markers like magnetic strips or QR codes; instead, it uses LiDAR to scan the tunnel environment in real-time and build 3D maps, enabling autonomous path planning, dynamic obstacle avoidance, and precise positioning with an accuracy of ±10mm. It supports dual control modes—wireless remote control and autonomous navigation—with seamless signal coverage throughout the tunnel, allowing for manual fine-tuning during alignment or automated transport via preset paths to meet the dual needs of flexible control and unmanned operation. Equipped with a high-capacity industrial battery, it supports multiple transport runs on a single charge, offering reliable, long-lasting endurance suited for extended tunnel construction operations. III. Product Features
Stable Heavy-Duty Performance for Tunnel Operations: Designed with a 30-ton rated load capacity, the vehicle combines a high-strength chassis with heavy-duty wheel assemblies to stably transport large-diameter pipes. It navigates complex tunnel conditions—such as slight surface irregularities and gradients—without the risk of tipping.
Laser Navigation for Flexible, Trackless Movement: Eliminates the need for physical tracks or ground markers; laser SLAM technology maps the tunnel environment in real-time and autonomously plans optimal routes. It easily handles curves and narrow passages, offering low implementation and operating costs.
Dual-Mode Control for Precise Docking: Features both wireless remote control and autonomous navigation modes. Remote control allows for millimeter-level fine-tuning to ensure precise pipe alignment, while autonomous mode enables preset workflows, reducing the need for manual intervention and enhancing personnel safety within the tunnel.
Comprehensive Safety Protection: Equipped with multiple safety systems—including LiDAR and ultrasonic sensors—to detect personnel and obstacles in real-time. Automatic deceleration or emergency braking prevents collisions, while the chassis design incorporates anti-slip and anti-rollover features suitable for wet or slippery tunnel surfaces.
Low Noise and Low Consumption for Confined Spaces: Utilizes a quiet drive system suitable for enclosed tunnel environments. Battery power ensures zero exhaust emissions, maintaining air quality and meeting green construction standards.
