Mi-Jack Products designs, manufactures, and distributes Rubber Tired Gantry (RTG) cranes and material-handling equipment. Founded in 1954 by Jack Lanigan Sr. - who developed a boom crane capable of lifting utility poles from the back of a truck - the company has expanded from its Illinois base into national and international markets. The family-owned business acquired manufacturing rights to the cranes it had been distributing in the early 1980s, establishing itself as a recognised global leader in RTG crane innovation.
The company operates from headquarters in Hazel Crest, Illinois, with four regional offices and five sales locations across its footprint. Its product lines include the Travelift® and Translift® RTG crane ranges, which form the core of its industrial operations. All cranes are manufactured to ISO 9001:2015 certified standards, reflecting the company's commitment to quality management in a specialised manufacturing environment.
Technical development remains central to Mi-Jack's strategy. The company has developed the Mi-Star™ automation platform for crane operations and is advancing hydrogen-powered drivetrain innovations. These efforts exemplify a continuing focus on automation, sustainability, and the technological modernisation of material-handling equipment across ports, yards, and industrial facilities.
