Topsky Tianlong Tantu 120-Y

At the edge of a serious industrial fire, every commander faces the same tension: the water has to reach the heat, yet nobody should be standing anywhere near it. The Topsky Tianlong Tantu 120-Y resolves that tension by sending the nozzle forward on rubber tracks while the operator stays well back. This diesel-hydraulic crawler moves through smoke, run-off and debris, delivers water or foam from a large-flow cannon and reports what the surrounding air contains. It is built for the long, high-volume work of containing a fire that cannot be fought at close quarters.

Robots Europa, based in Dublin, supplies the Topsky Tianlong Tantu 120-Y to fire and rescue services, industrial site operators and emergency-response organisations throughout the European Union and the DACH region. Robots Europa prepares each quotation for the configuration a customer requires. It also arranges delivery and provides after-sales support for customers in these markets.

Background

TOPSKY and the Tianlong name

The robot is produced under the TOPSKY brand. The Tianlong name also appears on other TOPSKY platforms in our range. In the source material for this product, the machine is identified by the model designation RXR-M120D and described as a crawler-type, medium-sized, oil-powered fire extinguishing robot. The figures on this page are given for that designation.

Firefighting robots of this class belong to a category of unmanned ground vehicles that fire brigades and industrial fire teams deploy where crews would otherwise be exposed to collapse, explosion, toxic smoke or radiant heat. The operator places the robot, directs the monitor and withdraws it again, all from a protected position. The crew is then free to manage hose lines, water supply and the wider incident.

Diesel power and a closed hydraulic drive

The Tianlong Tantu 120-Y is powered by a diesel engine with a rated output of ≥30.1 kW at 2400 rpm. The engine drives a closed hydraulic system, which in turn drives ASV rubber tracks for high-speed travel. Speed is adjusted steplessly from the remote control, so the operator can creep the robot into position beside a hazard or move it briskly across open ground.

Diesel power determines how the machine fits into an incident. A 50L fuel tank gives up to 6.5h of continuous operation on a full tank, and the hydraulic system does more than move the tracks. A reserved hydraulic output interface supplies a pressure of 16MPa and a flow of up to 25L/min. It is intended for hydraulic equipment such as breaking tools, generators, high-pressure water pumps and welding machines. The robot can therefore act as a mobile power source at the scene as well as a monitor carrier.

What sets a diesel crawler like the Tianlong Tantu 120-Y apart?

Many remotely operated firefighting robots are electric. The Tianlong Tantu 120-Y takes a different route, and it shows in how the machine is used. With a 50L tank and up to 6.5h of continuous operation on a full tank, endurance becomes a matter of fuel logistics, which most fire services already manage for their pumps and generators.

The diesel-hydraulic layout also gives the robot the mass and pulling power that heavy hose work demands. The robot weighs ≥1350kg and produces traction of ≥8.07KN. It can tow 120 m of charged DN80 or DN65 hose into position and hold its ground against the reaction of a monitor flowing 121.7L/s.

Its ground clearance of ≥270mm, an obstacle height of ≥300mm and a climbing ability of ≥25° let it cross the kerbs, rubble and ramps of an industrial site. With a wading depth of ≥300mm, it can pass through the pooled run-off that collects during a long firefight.

The reserved hydraulic output interface is the other point of difference. A robot that can run hydraulic breaking tools or a hydraulic generator remains useful once the fire is knocked down, when the work turns to opening access and restoring power.

How far can the Tianlong Tantu 120-Y work from its operator?

The robot offers several layers of stand-off distance. The wireless remote control reaches ≥1000m, so the operator can stay outside the hazard zone and, where the scene allows, beyond the reach of a potential blast or toxic plume. The hose the robot carries extends its reach forward from the water supply by 120 m.

The cannon itself throws water ≥96.5m and foam ≥92.3m. The robot therefore does not have to stand beside the burning object to apply agent effectively.

A wired remote control is also provided, which is useful where radio conditions are poor, for example in steel-framed structures or below ground. On-board sensors for 14 kinds of gases, temperature and humidity give the operator information from the robot's own position, so the crew can judge the atmosphere before anyone moves closer.

Who is the Tianlong Tantu 120-Y for?

The primary buyers are municipal and regional fire and rescue services that respond to large industrial incidents. For them, a robot that carries the monitor forward reduces the number of firefighters who must work inside the collapse and heat zone.

Industrial fire brigades at refineries, chemical plants, tank farms and large logistics centres are a second group. They face high fire loads and long-duration incidents, which suit a diesel machine with a large-flow cannon.

Operators of road and rail tunnels, ports and underground infrastructure form a third segment. Smoke, limited access and difficult radio conditions are routine in these settings, and the combination of wireless and wired control is relevant to them.

Organisations whose priority is reconnaissance, inspection or payload transport rather than fire suppression should consider the broader range of unmanned platforms in our UGVs category. Robots Europa can advise on which platform matches the task.

What is the Tianlong Tantu 120-Y used for?

1. Petrochemical and tank-farm fires: delivering water or foam over long distances to burning tanks and process units while crews remain at a safe distance.
2. Warehouse and large-span building fires: advancing the monitor into structures where roof or shelving collapse makes manual entry unsafe.
3. Tunnel and underground incidents: carrying hose and cannon through smoke-filled passages under wired or wireless control.
4. Hazardous-atmosphere assessment: measuring gases, temperature and humidity at the robot's position before personnel approach.
5. Cooling of exposed structures: sustaining high-volume water application on adjacent tanks, vessels or buildings during a prolonged incident.
6. Powering hydraulic tools on scene: supplying breaking tools, generators, pumps or welding machines through the reserved hydraulic output.
