Description

Allen Engineering WB2434: Maximum Reach Bridge Paver Machine

Expansive Reach with Superior Rigidity

The WB2434 from Allen Engineering stands as the largest and most advanced work bridge in the lineup. Contractors choose the WB2434 when projects demand long-span access, rigidity, and adaptability across bridge decks, highways, or airport slabs. With the ability to extend up to 120 feet, this bridge machine ensures unmatched access and structural stability for finishing operations such as curing, texturing, bull-floating, and burlap dragging. Because of its heavy-duty construction, the WB2434 supports large-scale work while maintaining accuracy and safety.

Rigid Frame for Large-Scale Projects

The WB2434 includes a cable tensioning kit that reinforces rigidity, minimizing flex or bounce across wide spans. Crews benefit from a stable, secure platform that improves precision during finishing tasks. This feature makes the WB2434 an essential companion to any paver machine, giving teams the ability to follow placement closely and maintain consistent slab quality. By reducing variability, it helps contractors meet DOT specifications and demanding project standards with confidence.

Powered Mobility with Kohler Reliability

The WB2434 operates with a 9.5-horsepower Kohler CH395 engine, providing dependable performance and efficient movement. When paired with the optional powered mobility system, crews reposition the work bridge easily, reducing labor and boosting jobsite efficiency. Multiple wheel options, including cupped wheels, rubber tires, and even all-wheel drive, add flexibility across different site conditions. Compared to smaller units, this system allows the WB2434 to integrate seamlessly with road paver machine workflows in high-output environments.
