The Topsky Tianlong Tan Tu 120-K is a tracked firefighting robot built around a high-flow integrated fire monitor with a rated flow of 1,000 L/min and a maximum spray range of 120 m, providing substantial stand-off suppression capability for industrial fires, petrochemical incidents, warehouses, and tunnels. The motorized monitor rotates a full 360° and pitches from −15° to 60°, giving operators precise nozzle control via remote connection while remaining at a safe distance from heat, smoke, and hazardous materials. Weighing 500 kg and with a payload capacity of 120 kg, the tracked chassis navigates debris, hoses, and uneven surfaces with a 35% climbing grade, 60 mm obstacle-crossing height, and 140 mm trench-crossing width.

Integrated sensing supports real-time toxic and harmful gas detection alongside video monitoring and telemetry, enabling operators to monitor atmospheric conditions and robot status simultaneously during an incident. A cloud platform connectivity concept allows coordination with multiple units and incident management systems. Maximum traction force of 2,600 N adds logistics utility for hose management and equipment repositioning, while support for strong ventilation and high-temperature smoke management positions the 120-K as a multi-role platform for suppression, reconnaissance, and scene conditioning in high-risk environments where direct firefighter access is restricted or inadvisable.
