Chris McLoone from Fire Apparatus Magazine visited Bronto Skylift factory and local fire station in Tampere.
"The second facility we visited is the Pori factory where the booms are built. The engineering is exacting, as you’d imagine. According to Goyer, the stability we experienced up in a 90-meter Bronto in 30-mileper-hour (mph) winds is derived from the construction of the boom, which allows for the rigid feeling at 92 feet horizontal and at full height with only a 23-foot total jack spread. These booms are massive when you see them up close on a rig, and seeing them under construction is also impressive.
Bronto also builds the cages (or platforms) for the end of the booms in Pori. These cages can have ports for hydraulic tools, have supplied air, and also can carry monitors for master streams. For example, the 90-meter unit in which we ascended can flow up to 1,000 gpm at 88 meters."
