Meticulously engineered. Flawlessly produced.

For over three decades, J&R has provided unmatched quality by engineering, designing, and manufacturing the world’s most complex lifting solutions.  Headquartered in Mukwonago, Wisconsin, J&R Engineering is located in the beating heart of America’s Midwest. We’re a company with roots in small town USA; however, we’re far from the little consulting firm we were founded as thirty years ago. As we’ve grown and developed, we’ve emerged as a 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 travel, 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 has virtually invented the hydraulic gantry market. This means that we understand gantries on a level that most companies never will. We’re an organization that sees complicated lifting challenges as opportunities, and we’re constantly developing new ways to approach—and ultimately change—the way gantries perform.

Our hydraulic boom gantry systems offer a number of benefits that are both cost effective and versatile. They are also specifically customized to address the individual concerns presented by each particular challenge. Add in J&R’s proprietary LIFT-N-LOCK® cam lock system, and the result is a gantry solution that doesn’t just deliver performance, but peace of mind as well.
