This advanced Top-Arch Assembly Machine is engineered for tunnel construction with a versatile operating width range from 5m to 25m.

Adopting a hybrid design of diesel and electric power, the diesel engine provides high-intensity operation power in the tunnel (according to the National III emission standard), while the electric motor (IE3 high-efficiency three-phase asynchronous) meets the construction needs of urban areas or enclosed spaces with low noise and zero emissions.

• Power switching response time is less than 30 seconds
• Dual power redundancy design ensures 50% of basic operational capacity during single system failure
• Significantly improves continuity of tunnel construction

Engineered for extreme environments with advanced technology:

• Maintains rated power output at 4500 meters altitude
• Operates in temperatures from -25℃ to 50℃
• Power attenuation rate less than 8% (industry average 15%)
• Hydraulic system with constant power control and oil temperature adaptive adjustment

• CAN bus control system for pre-programmed arm movement trajectory
• Collision warning and automatic obstacle avoidance functions
• Remote monitoring platform for real-time equipment parameters
• 3D construction logs and big data analysis capabilities

• Patented folding protective shield (CN222879688U) creates 2.5m² anti-rockfall area in 0.5 seconds
• Mechanical arm hydraulic locking + electrical interlock dual safety system
• Wireless remote control with 50 meter radius
• Centralized lubrication system reduces maintenance time by 60%
• High-altitude oxygen cabin type cab

This versatile Arch Installation Trolley is ideal for:

• Tunnel construction projects
• Urban underground space development
• Emergency rescue operations
• High-altitude construction environments
• Extreme temperature conditions
