J&R Engineering Specifications

J&R Engineering has provided unmatched quality by designing, and manufacturing the world’s most complex lifting solutions.  

Headquartered in Mukwonago, Wisconsin founded thirty years ago. As we’ve grown and developed, we have emerged as the world leader in hydraulic boom gantry engineering and design. We’ve expanded beyond the United States and Canada, and provided our hydraulic boom gantry products in places as far away as Saudi Arabia and Mexico. But no matter how far away from Wisconsin, we always stay true to our roots by providing products that are exceptionally safe, demonstrate superior performance, and are manufactured to the highest standards of quality possible.

Having played an integral role in the development of the first commercially available telescopic hydraulic gantry, J&R Engineering has not only virtually invented the hydraulic gantry market but revolutionized it.  We understand gantries on a level most companies never will and as an organization view complicated lifting challenges as opportunities, and we are constantly developing new ways to approach—and ultimately change—the way gantries perform.

Our hydraulic boom gantry systems offer unique benefits that are both cost-effective and versatile. They are also specifically customized to address the individual concerns presented by the challenges each and every heavy lift solution requires.  Add in J&R’s proprietary LIFT-N-LOCK cam lock system, the results are gantry solutions that not only deliver performance but peace of mind to ensure the most complex lifting solutions are safely and expertly completed to exceed the demands our worldwide clients have come to expect from J&R Engineering.
