Game-Changing Solutions for Bridge Inspection Contractors
The Anderson UnderBridge Advantage for Contractors
Decades of collaboration with construction and maintenance professionals have shaped our ability to design equipment specifically engineered to overcome the challenges contractors face beneath bridge structures. When you partner with Anderson UnderBridge, you gain access to:
Support up to 1,400 pounds with expansive platforms that accommodate multiple workers, tools, and materials simultaneously. Our platforms provide significantly more workspace than bucket trucks, enabling efficient staging of materials and equipment.
Integrated power, air, and water connections eliminate the need for additional equipment, simplifying setup and operation during gunite repairs, surface preparation, and painting projects.
Whether you need equipment for long-term ownership or project-specific rentals, Anderson UnderBridge supports your business model with purchase and rental options that optimize your capital investment.
Our platforms provide the stable, spacious environment painting contractors need for the efficient application of protective coatings. The ability to move along the bridge without retracting equipment significantly accelerates project timelines.
The stability and capacity of our platforms make them ideal for precise concrete form placement during construction projects. Our equipment’s ability to be craned into position on trophy spans provides exceptional versatility on new construction sites.
When unexpected damage requires immediate attention, our nationwide delivery capabilities and rapid deployment equipment get your crews on the job, and fast.
