Fire Ladder Trucks Views
The fire engine may have several methods of pumping water onto the fire, such as passing water obtained from a fire hydrant through hoses or using a pumping cannon (also known as a monitor or deck gun); some trucks have an onboard water reservoir. Some fire engines may carry ladders to gain access to fires occurring in high-rise buildings and remove casualties, or hooks used to pull walls away to expose hidden fire or break windows. In some regions, a rescue unit is an EMS truck with tools to carry out technical rescues of people from traffic collisions or structural collapses.
A tiller ladder, also known as a tractor-drawn aerial or hook-and-ladder truck, is a specialised turntable ladder mounted on a semi-trailer truck. It has separate steering wheels for front and rear wheels. This truck is primarily used in the United States, especially in areas with narrow streets that prevent longer rigid-bodied trucks from entering such as San Francisco and Washington, DC. The hook-and-ladder concept started when taller skyscrapers and more city streets became a problem for fire departments. Larger ladders were needed to get to the upper stories of buildings, and the only way to move them was in this format.
A hydraulic platform, also known as articulating booms, Snorkels, platform trucks, Bronto (used in Australia) or sometimes shortened to just HP, is a specialised 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.
Before long, the turntable ladder—which was even longer, mechanically-extendable, and installed directly onto a fire truck—made its appearance. Since the late 1930s, the longest turntable ladders have reached a height of 150f feet (46a m), requiring the aforementioned tiller trucks to carry such ladders.
