These monster tools help us maintain the most hard to reach areas of our city bridges.  With two locations nationally, we are poised to serve the entire Western United States. 

Go Big With Our HPT66 Truck-Mounted Underbridge Platform


When the job you need to do is big, you need a big platform and that’s what you get with an HTP66. We can help you take on that task with this 66-foot truck-mounted platform that can be lowered 22 feet and reach 4,100 square-feet of underbridge area from one placement.

You know that time is money and the overwhelming time savings of not having to use scaffolding is tremendous. In fact, instead of hours spent setting up, using the HPT66 means your crew can be at work 15 minutes after you’ve positioned it on the bridge and begin positioning the platform.


The massive HPT66 is our top-of-the-line truck-mounted platform.


HPT66 EquipmentThe HPT66 truck-mounted platform is a fully equipped underbridge access and work platforms, which are mounted on diesel-powered trucks. These state-of-the-art access platforms are the most versatile devices for inspections and under-bridge operations. The HPT66 features a patented Tower Separation System (TSS), featuring hydraulically adjustable cross linking arms between the main outside vertical tower and the turntable sub-frame, mounted on the truck.

This system allows operators to erect and extend the tower and the platform to provide easy access over sidewalks, railings and other barriers without restricting your underbridge operations. The main operating system is a silenced 30 kW diesel generator with a hydraulic pump that reduces fuel consumption and pollution during operation by 50 percent.

In addition, the HPT66 platform offers standard Dual Side Hydraulic Outrigger Stabilizers to provide maximum stability and a high level of safety. All of these features come together to make the HPT66 an efficient and effective solution for bridge inspection, repair and under-bridge maintenance tasks.
