CR 137

E-ONE CR 137 Aerial

Tallest Ladder In North America

The E-ONE CR 137 Ladder is North America’s tallest aerial, capable of reaching heights exceeding 13 stories. This ladder extends to an impressive vertical height of 137 feet, while also offering a horizontal reach of up to 126 feet, making it highly effective in accessing elevated areas and distant targets during emergency situations. With its superior reach, the CR 137 is ideal for departments that frequently handle rescues, high-rise operations, and large-scale firefighting scenarios.

E-ONE CR 137 Aerial Ladder

One of the most notable aspects of the CR 137 is its structural integrity. Engineered to exceed the National Fire Protection Association (NFPA) standards, this aerial boasts a structural safety factor of 2.5 to 1, compared to the NFPA’s minimum standard of 2 to 1. This translates to a ladder that is 25% stronger than many other aerial options, providing firefighters with enhanced confidence in its durability and stability. E-ONE’s design approach ensures that every part of the CR 137, from the base to the tip, is crafted to support the ladder’s exceptional height and reach without compromising safety or performance.

The construction of the CR 137 ladder reflects E-ONE’s commitment to creating durable, high-performing equipment for firefighters. By building this ladder from the ground up with strength as a priority, E-ONE has created an aerial capable of withstanding the rigors of daily firefighting and rescue operations. This design not only adds an extra layer of reliability but also instills trust among firefighters who depend on their equipment to keep them safe in high-stakes situations.

The E-ONE CR 137 Ladder combines unparalleled reach with an industry-leading structural safety factor, making it the go-to choice for fire departments that require a robust, high-reaching aerial for challenging rescues and firefighting tasks. Its exceptional height, extended reach, and reinforced strength set a new standard for aerial apparatus in North America.

Reach a Target That is 110’ High and 80’ Horizontally Off The Side
