The Terex hydra platforms HP 32 and HP 35 trailer-mounted platforms feature a well-balanced design, three-axle configuration and 1,500-lb. (680 kg) tongue weight, so the models are easily towed to the job site by one-ton pick-up trucks, according to the manufacturer.

These self-contained units are fully functional on their own, so the tow vehicle can drop them off and leave the site to handle other tasks. At less than one-half the cost of truck-mounted platforms, these low-investment models are practical for bridge inspection, maintenance, restoration and utility work.

These under-bridge access platforms come standard in two platform lengths: the 32-ft. (9.8 m) HP32; and the 35-ft. (10.7 m) HP35. Both models boast 1,000-lb (454 kg) platform capacity, enough for up to three workers plus tools. While standard at 32 and 35 ft. (9.8 and 10.7 m), platform lengths can be customized to fit customer and job site requirements. The models also can be equipped with a special 12.5-ft. (3.8 m) long by 4-ft. (1.2 m) wide bridge worker platform designed specifically for the removal of overhang brackets.

Dual hydraulic outriggers positioned at the trailer ensure stabile platform operation when deployed and can be mounted on either side of the trailer for left- or ride-side platform deployment. Powered by an on-board 18-hp (13.4 kW) gas engine with auto-idle, the self-erecting platform deploys in five minutes and requires only a single lane closure to operate. A hydraulically powered front drive wheel controls trailer movement on the bridge deck.

Both the HP32 and HP35 models feature the Terex hydra platforms tower separation system. Offering a maximum 7.7-ft. (2.3 m) extension, the system includes hydraulically adjustable cross-linking arms and a level walkway with rails connecting the trailer to the vertical tower. The crossover offers a maximum 5-ft. (1.5 m) vertical rise to clear obstacles on the bridge deck without the need to retract the platform.

Offering a 180 degree platform rotation and maximum lowering depth of 18 ft. (5.5 m), the HP32 and HP35 make quick work of bridge inspection and restoration projects. The platform’s maximum 3.5-ft. (1.1 m) width offers ample space for completing projects. A voice-activated communication system connects workers on the platform to personnel at the main control of the trailer, enabling efficient trailer movement without leaving the platform.

An auxiliary hydraulic pump and motor system enables the platform to be retracted to transport position should an issue arise with the main hydraulics.

“At no time are the workers disconnected from the bridge deck like they are with traditional lifts,” said Christer Bradley, director of sales and marketing, under-bridge access platforms of Terex Roadbuilding. “Power failure does not prevent the worker from returning to the deck when using our unit.”

Options such as a generator and air compressor to power tools required for bridge maintenance and restoration increase trailer-mounted platform versatility in the field. An available 3.3-ft. (1 m) scaffold lifts the worker above platform level for close inspection and work in between girders.
