Dan McInerney recently stumbled upon an intriguing article about the world's tallest firefighting aerial device, the Bronto S-112 HLA. According to the piece, there has to be a compelling reason to stand in an open-air basket 367 feet above the ground. While hot air ballooning might offer a similar bird's-eye view, the Bronto S-112 HLA serves a more practical purpose—repairing structural damage at iconic locations like the tops of famous cathedrals.
The accompanying image from GIZMODO.com shows just how massive this machine is. Even when compared to towering structures such as the Amiens Cathedral or stacked groups of people, the Bronto S-112 HLA reigns supreme as the tallest. Manufactured by Finland-based Bronto, this beast holds the world record for the highest-reaching basket lift. What makes it even more impressive is its ability to not only ascend but also bend its crane arm at a 90-degree angle, 290 feet up (equivalent to around 26 stories), while extending its working radius to 82 feet—approximately the length of three Minke Whales or two 72-passenger school buses. This design allows firefighters and maintenance crews to access otherwise unreachable spots, like the undersides of wind turbine rotors.
For such a towering apparatus to function effectively, stability is key. That’s why the lifting assembly sits on a robust Mercedes-Benz model 76.60 nine-axle commercial truck chassis equipped with five steerable axles and four drive axles. The whole setup tips the scales at a solid 75,000 kilograms, which is roughly equivalent to two Doosan Moxy articulated dump trucks. To ensure safety and efficiency, the rig features an automatic leveling system that deploys in under a minute, allowing rescuers to act swiftly in emergencies. Additionally, the Telecontrol system includes a visual interactive display for enhanced operator control.
A video clip showcasing the S-112 HLA in action during the Inter-2010 event in Leipzig highlights its dynamic capabilities. As described by Bronto themselves, the High Level Articulated (HLA) series stands out as the pinnacle of high-rise rescue and firefighting technology. Its standout features include superior vertical and horizontal outreach across all heights, swift and secure operations, and a corrosion-resistant waterway system. Mounted on a standard truck chassis, the HLA unit remains both flexible and compact enough to navigate regular roads and streets en route to emergencies. Once deployed, the auto-jacking function stabilizes the unit in just 40 seconds, enabling rapid response from heights exceeding 33 stories. Currently, the range supports working heights ranging from 81 to 112 meters.
If you're interested in learning more, Bronto offers downloadable brochures detailing the full specifications and capabilities of their HLA series. It’s clear that innovations like the Bronto S-112 HLA represent significant advancements in urban firefighting and emergency response, ensuring that no corner of a city—or skyward structure—is left unreachable in times of crisis.
