An invention must address a real problem—and few have been more painfully evident than the one revealed during the 2017 Grenfell Tower fire, in which 72 people lost their lives.
As the 24-storey building burned, it became tragically evident: there was no way to get water quickly to the upper floors where people were trapped. Traditional methods simply couldn’t reach them. The Fire Spyder™ was developed to change that. It offers a practical and rapid means of delivering water—and other critical logistical support—from the outside, when every second counts and lives hang in the balance.
“...It was soon clear that the fire was far too big for the fire brigade to control. It was just too high and out of reach...”
—Witness statement, Grenfell Tower Public Inquiry
The Fire Spyder™ is a multi-functional, winch-based system designed to support fire and emergency operations in tall buildings. Referred to as the Swiss Army knife of high-rise firefighting, it offers a wide range of capabilities in a single, compact setup. Mounted on a fire truck, the system enables exterior firefighting and logistical support without relying on permanent building infrastructure.
Designed for flexibility and speed, the system can lift hoses, air bottles, and other essential equipment—all in one go—to upper floors, and then attack the fire from the outside. By handling the heavy lifting, it greatly reduces firefighter fatigue during initial deployment and operations. This is especially valuable at heights beyond the reach of traditional aerial ladders. The system has a compact footprint, is straightforward to operate, and can be deployed rapidly by trained firefighting personnel.
Following a successful proof of concept—conducted in cooperation with the Ho Chi Minh Fire Academy and witnessed by Bureau Veritas—the start up behind Fire Spyder™ is now working to develop a minimum viable product for further testing and evaluation.
Exterior Fire Attack
Enables direct firefighting at heights both above and within traditional ladder reach, bypassing interior obstacles.
Logistical Support
Rapidly lifts critical equipment—such as air bottles, hose packs, and tools—all in one go—to operational floors, reducing firefighter workload and speeding up response times.
Improvised Standpipe
Can be used to rig an exterior hose line as a standpipe when internal systems fail or are absent.
Incident Monitoring
Supports the attachment of infrared and other monitoring cameras to assess fire floor conditions and developments in real time.
Power and Air Supply
Capable of delivering auxiliary power lines and a high-rise FARS—an air standpipe system supplying breathable air to firefighters operating in tall buildings.
Medivac Capability
Can lower injured firefighters or civilians using devices like a Sked or Stokes basket, facilitating rapid and safe evacuation.
Fire Spyder™ Featured in Fire & Safety Journal Americas
I'm proud to share that Fire Spyder™ is featured in the June 2025 issue of Fire & Safety Journal Americas (FSJA)—a respected publication read by fire professionals, engineers, and public safety leaders across the Americas.
In an article titled “The Swiss Army Knife of High-Rise Firefighting,” I explain the concept behind Fire Spyder™—a system I invented to deliver water and essential equipment externally to high-rise fires, far beyond the reach of traditional fire ladders.
The feature covers:
“I’m honoured that FSJA chose to spotlight this innovation. With more high-rise buildings going up every year, we urgently need smarter, faster systems for vertical firefighting operations.”
— Thomas Jonkers, Inventor, Fire Spyder™
Fire Spyder™ can operate up to 125 meters (410 feet) in height—almost double the reach of the tallest fire truck ladders in use today. It's compact, flexible, and built to function in dense urban environments where conventional aerial options fall short.
After completing a successful proof of concept in Vietnam, I’m now looking to build a Minimum Viable Product (MVP) in partnership with a professional fire service. This will allow us to test the system under real-world conditions and move closer to deployment in cities where vertical growth presents major firefighting challenges.

In June 2025, Fire Spyder™ will also be featured in an episode of the Firefighter Podcast, hosted by active firefighter Pete Wakefield.
As one of the most respected voices in the fire service community, Pete’s podcast reaches a global audience of frontline firefighters, officers, and safety professionals. The episode will explore the inspiration behind Fire Spyder™, how it works, and what it means for the future of high-rise firefighting
The Firefighters Podcast, is a globally recognized platform dedicated to celebrating and supporting emergency service professionals. Since its inception in 2020, the podcast has released over 370 episodes, offering in-depth conversations that explore the challenges, innovations, and personal stories within the firefighting community.
With a mission to inspire, connect, and motivate, it serves as a valuable resource for both current and aspiring first responders.

At the core of the Fire Spyder system is the monitor plate—a triangular assembly that is winched up along the building façade during a fire emergency. Constant-tension wires at each corner provide stability during exterior operations and create lifting leverage, allowing the system to support demanding high-rise operations.
Items such as hose packs, breathing air bottles, and other equipment can be quickly secured to the monitor plate and hoisted at full winch speed to designated operational floors. The fire attack hose, already connected to the monitor plate and fitted with a nozzle, is lifted simultaneously for immediate exterior firefighting.

Inspired by the Grenfell Tower fire.
Why isn’t it possible to launch a powerful exterior attack above traditional ladder reach?
Provisional patent was filed in the USA.
A basic prototype was built to support the provisional patent application.
Fire Spyder™ was showcased at the Geneva International Exhibition of Inventions
Awarded a Bronze Medal. The concept was well received, with strong audience understanding and support.
A full-scale Proof of Concept was carried out using the high-rise practice tower of the Ho Chi Minh Fire Academy.
The test, conducted with live fire and operational drones, was supported by academy instructors and students. The full deployment sequence was successfully executed and independently validated by Bureau Veritas.
2025 – In May, a patent application for the Fire Spyder™ was filed under the PCT route, covering the USA, UK, Europe, and China.
The invention is now officially patent pending.
2025 – Fire Spyder™ will be featured in the
Fire & Safety Journal AMERICAS
The Fire Spyder™ system offers two distinct deployment modes:
1. High-Rise Deployment (Up to ~125 meters)
For buildings between 70 and 125 meters, deployment typically requires a drone to carry a lightweight messenger wire to the roof. This wire is then used to pull the main work wire, enabling the hoisting of hoses, equipment, or firefighting nozzles.
The use of drones in this scenario is dictated by payload limitations and the inaccessibility of upper levels from the ground.
2. Mid-Rise Deployment (20 to 70 meters)
In mid-rise structures, drones are generally not needed. The work wire can be manually deployed from the roof, balconies, or even windows, simplifying setup and speeding up response time.
As a standard operational model, calculations are based on the use of a 2.5” attack hose, winched to approximately 90% of the building’s height. This provides sufficient reach for most high-rise operations while keeping equipment loads manageable within current drone and winch capabilities.
Note: These height ranges are indicative. The Fire Spyder™ system has been engineered with flexibility in mind and may be suitable for taller structures depending on specific operational needs and site conditions.
