North American Industries specializes in designing cranes for bridges and elevated highways
to handle the materials necessary for repairs and construction projects. At one time, highway and heavy construction contractors would almost exclusively use towers and crawlers for job-site lifts. Now they are increasingly turning to overhead cranes for bridge, subway, and tunnel construction and repair. North American Industries custom engineers the cranes:
- with spans appropriate for the widths of the bridges or roadways (up to 150 ft)
- the ability to power through and navigate inclines
- the endurance for extreme weather conditions
- the ability to accommodate wind, flexing of the bridge, power source, and limited area
"Off the shelf" material handling equipment will not suffice for bridge work and elevated highway projects, however, because North American Industries is efficient in our made-to-order process, these custom cranes are designed at competitive prices.

Benefits of Our Gantry Crane(s)
- An Investment that can be reconfigured for the next project or resold (as opposed to renting equipment which can often incur as much cost)
- Often weighs less and requires less space than lattice-boom or hydraulic cranes
- More efficient because our cranes are designed specifically for the application
Difficulties with Lattice Boom and Hydraulic Cranes
Consider a work zone of limited area - the removal of decks from sections of active roadway, for instance. There is typically not enough room to set up a lattice-boom or hydraulic crane, and therefore the crane must be erected outside the work zone, often requiring that parts of the road be closed to traffic. Such an operation is then restricted to a few nighttime hours—sometimes as few as five, with two reserved for setting up and taking down the crane. And since the work crew must be compensated for a full eight-hour shift, wasted operating costs soon grow exponentially.
