Ascendant® Class of Aerials
Developed as part of a collaborative effort across Oshkosh Corporation, the Pierce Ascendant® Class of Aerials leads the industry with single-axle configurations for the Ascendant 107' Heavy-Duty Ladder and Ascendant 110' Heavy-Duty Platform. The innovation continues with the Ascendant 100' Heavy-Duty Tower, which can be configured with an overall length as short as 41' 3". Leveraging sophisticated engineering development approaches and materials science expertise, each product provides market disrupting advancements in maneuverability, drivability, operability, and serviceability, making it the aerial of choice and allowing firefighters to safely reach new heights.
Pierce Ascendant 107’ Heavy-Duty Ladder
This vehicle has redefined the single rear axle aerial market, granting firefighters unprecedented reach without sacrificing water capacity, performance or safety. The design of the ladder and other components allows for a significantly lighter vehicle in comparison to other aerial ladder systems, such as the 105’ tandem axle, improving stopping distance and reducing lifecycle and maintenance costs. It also clears the way for departments to better meet weight loading limits in weight restrictive states to utilize an Ascendant system.
A culture of collaboration
Before the Ascendant, most single rear axle quint aerial ladders couldn’t reach higher than 78 feet and had a limited rated tip load. Our global product development team pioneered a new way to challenge those limits. Our Pierce team combined material science breakthroughs with advanced engineering processes developed by Oshkosh to develop a new aerial ladder system and other revolutionary components. Those same innovations are also used to extend the reach and safety of JLG equipment, including the 1500 AJP and the 1850 SJ, the world’s tallest self-propelled articulated and straight aerial work platforms.
