Fire Apparatus USA 07
Fire Apparatus USA 07 : Types (2): Aerial Apparatus: (2) Hydraulic Platform: A Hydraulic platform, also known as articulating booms, Snorkels, platform trucks, Bronto (used in Australia) or sometimes shortened to just HP, is a specialized aerial work platform designed for firefighting use. They have a number of functions, which follow the same principles as the turntable ladder, providing high level access and elevated water pump positions. Some hydraulic platforms are articulated, which allows the arm to bend in one or more places, giving it the ability to go "up and over" an obstacle (such as a building roof). There are non-articulated platforms, based on standard aerial work platforms, although the most common type is the tower ladder (mentioned above). HPs (articulated or not) may still have a ladder arrangement fitted to the arm, primarily as an emergency measure. In some jurisdictions these can be denoted ladder platforms. Most HPs are designed to reach a height of around 33 metres (100 feet), although larger models are capable of reaching heights of over 100 metres (328 feet). Many HPs are fitted with additional equipment in the platform itself, which can include a control panel, lighting equipment, a fixed water outlet or monitor, power outlets or compressed air outlets (allowing the fixing of rescue equipment, such as hydraulic rescue tools). Many are also adapted or capable of carrying a stretcher. Some units have video systems and remote control in case of dangerous chemical fires. In an emergency, liquid-concrete pumping boom trucks can be temporarily repurposed for delivery of water for firefighting, as in the case of the Fukushima Daiichi nuclear disaster in 2011
