Automotive: Fifth Wheel Couplings and Towing Hitch

The range of stamped and deep-drawn parts comprises almost all types of alloy and all geometries. Production is carried out on hydraulic and eccentric presses from 25 t to 250 t. From the prototype and process development up to the series delivery, Hunger is always available for the customer to provide him with advice based on experience and creativity. In addition to our strong customer orientation, we consider the mechanical processing of the manufactured components to be one of our greatest strengths. This includes joining technology such as welding, riveting or crimp technology just as much as the production of assemblies and modules with subsequent surface finishing. We offer all standard procedures such as glass bead blasting, cathodic immersion painting or powder coating and galvanizing.

In 1995 Hunger presented a world first with the patented, maintenance-free luxury semi-trailer coupling. The coupling plate stands out due to its sintered-on antifriction coating, while the closing mechanism is designed so that the kingpin is enclosed by divided maintenance-free roller bearings. The greasing that is required for standard couplings as well as the grease supply are no longer necessary. In 2004, Hunger again presented a world first – the first maintenance-free semi-trailer coupling made of full aluminium. The clear advantages of this innovation are a reduction in fuel consumption and an increase in the possible load. The hydraulic trailer coupling is also available in a version with full remote control.
