JOST Werke

JOST Werke SE is a leading global producer and supplier of safety-critical systems for the commercial vehicle industry, headquartered in Neu-Isenburg, Germany. Founded in 1952 by Hans Breuer and Joseph Steingass initially as a manufacturer of ball wreaths, the company expanded into fifth wheel production by 1956 and grew through international plants in over 35 countries across six continents. Its core offerings span On-Highway applications for trucks and trailers, including fifth wheel couplings, landing gears, king pins, ball bearing turntables, and axle systems under the JOST brand, alongside container equipment and steering solutions from TRIDEC. The ROCKINGER brand provides towing hitches, drawbars, and eyes for transport and agriculture, while Quicke specializes in front loaders for tractors and forestry machinery. Since 2025, the acquisition of Hyva has enhanced its portfolio with tipping cylinders, container lifting systems, and cranes for off-highway sectors like construction and mining. Employing over 7,500 people, JOST Werke SE generates primary revenue from Europe and serves transport, agriculture, and construction industries with reliable, innovative components.
