Bridge, Infrastructure, Heavy Civil

Efficient access for your next bridge, dam or utility project

Multiple crews work effectively from one access solution – maximizing time, reducing schedule challenges and increasing profits. Klimer’s heavy-duty KPM-8 boasts fast travel speeds of up to 30′ (9.14 m) per minute and heavy-duty capacities keep trades, tools and material at optimal working height. Savings on challenging bridge work are realized quickly with fewer trips. Klimer’s tie-in design allows platforms to be positioned back from the pier facade for uninterrupted access to the façade. Gas-powered engines eliminate the hazard of hanging cables and increase site organization and containment.

Work such as concrete chipping, forming, pouring, drilling of anchors and concrete replacement is performed directly from the work platform, at optimal working height. Klimer’s versatile design allows platforms to be twinned at lengths up to 141′ (42.98 m) providing access from pier to pier. Enjoy increased access to work area and exposure to facade.

Klimer’s pedestal base can be engineered to fit into tight or limited spaces and may be customized for specific conditions. Our engineering, drafting and consulting services deliver superior access and ensure superior profitability on your next bridge, infrastructure or heavy civil project.

A total of eight Klimer platforms were used for access on two of the tallest piers (approx. 100 ft high).
The project involved restoration and repair of deteriorated piers plus partial replacement of rebar: concrete chipping, forming, pouring, drilling of anchors, concrete replacement and restoration. A combination of Alimak drive units and KlimerLite decks delivered optimal access. The eight Klimers were twinned at the start of the project for access across the top of the piers. The platforms were split as work progressed and they moved down the pier columns.

“We realized efficiencies in being able to take equipment and tools onto the platform. We were able to work faster, with less up and down travel time,” said General Foreman Mark Grenier. “The Klimer platforms gave us convenient access to electrical. Our site was more organized and better-contained. I’d like to have Klimer platforms on every job!” he added.

Estimator and Project Manager Sean Firth decided to use Klimer platforms was determined through his evaluation of manpower-time to install traditional scaffold on taller piers vs. mast-climbing work platforms.

“The speed at which the Klimers could get into service was far greater and more efficient,” Sean noted. “We also saw increased ergonomics by placing platforms and men where the work needed to be performed. There’s less overall physical effort.”

With the capacity to place men and materials on the platform, fewer vertical trips are required. Sean saw time savings of approximately one man hour per worker per day. Over the course of a day, week and the term of the project amounted to considerable savings.

KlimerLite Mast-Climbing Work Platform

KlimerLite twin-tower mast-climbing work platforms, totalling 80 feet long and 55 feet high, facilitated concrete restoration to a bridge pier including damaged concrete removal, steel treatment, installing anodes, forming and pouring.

Platforms were lifted onto the pier from a barge at high tide. Pedestals of the units were modified to sit on a meager four-foot, eight-inch base. Tie-ins were designed specifically to allow the KlimerLites to sit back 20 inches from the pier facade.

“Normal staging would have required installation of a complex outrigger system to allow the scaffold set up,” noted ACT Project Manager Carl Nunes. “With the KlimerLite and small pedestal, this situation was not a factor that needed to be addressed,” he added. KlimerLite twin-tower platform length allowed for a large work area and great exposure of the facade. It also allowed a crew of six on the platform – three times the manpower compared to aerial platforms.

Klimer provided custom platforms for crews to install stay cables on Delaware’s Indian River Inlet Bridge.

Custom Telescopic Platforms Provide Access to Bridge Cable-Stays

Delaware’s Indian River Inlet Bridge Project is a $150M design-build construction by Skanska USA of a three-span cable-stayed bridge (400’-950’-400’) with flanking approach spans and a pedestrian walkway. It is built to withstand a Category 5 hurricane. The cable-stayed superstructure consists of cast-in-place (CIP) concrete edge girders, with both precast and CIP concrete transverse floor beams, and a CIP concrete deck.

With the goal of providing Skanska a platform to meet the best possible design for maximized safety and efficiency; Klimer developed and created a custom platform for Skanska’s stay cable installation crew with custom telescopic platforms. Selecting the KlimerLite mast-climbing work platform and designing custom 9-ft translating extensions allowed access to both sides of the cable stays. Maximum efficiency was achieved by having access to both sides of the cable stay, which eliminated the requirement for a second platform. The telescopic access platforms enabled the crew to get close to the installation points of the stays on the outside of the pylons; They also allowed the crew to work ergonomically and safely by being able to extend and retract between different elevations of stays while being surrounded by guardrail 100% of the time.
