J&R was founded in 1978 as a professional engineering consulting firm primarily serving the crane manufacturing business. During it's early years, J&R was instrumental in the development of the first commercially available telescopic hydraulic gantries. With the development of the LIFT-N-LOCK Hydraulic BOOM Gantry in 1989, J&R discontinued offering engineering consulting services so that it could concentrate on the design and manufacture of it's own proprietary line of premier lifting equipment.In addition to it's gantry line, J&R designed and built the first ever tracked spent fuel dry cask Transporter. Other products are LIFT-N-BOOM 60 US ton mobiles and 1,200 US ton vessel dollies. Many of the safety and design features presented are proprietary products of J&R Engineering and are patent protected.
