Manufacturers

There are three major manufacturers of the Tiltrotator concept today (although similar products are sold by various competitors): * Rototilt Group AB (founded in 1973 by Allan Jonsson) who purchased Noreco in 1992, hired the Norgren brothers, and registered the brandname Rototilt. * Engcon (founded in 1993 by also ex-Noreco employee, Stig Engstrom) who started manufacturing their own product using only "tiltrotator" to avoid

Other companies manufacturing their version of tiltrotator on a smaller scale include Juhyun (주현), JK attachment (S.Korea), SMP, HKS, Kinshofer, Catsu, Giant China and Marttiini Metal under various product names as tiltrotator, swingrotator, swingotilt, MRT, Nox, Rotiltor etc., although it's still commonplace on the market as a
