JOST to showcase new modular systems at IAA Transportation 2026
JOST will bring a broad range of new components and systems to IAA Transportation 2026, with a particular focus on modularity, automation and electrification. Highlights will include the new ADDTRONIC fifth wheel platform, a modular ROCKINGER towing system and the DCA One4All axle platform.

JOST will showcase a broad portfolio of new components and technologies at IAA Transportation 2026, covering applications ranging from transport and logistics to construction, mining and urban mobility.
Among the main premieres in Hannover will be JOST ADDTRONIC, a new modular fifth wheel platform designed to allow functionality to be added or upgraded over the vehicle’s lifetime.

Based on standardised interfaces, the system supports upgrade packages covering areas including safety, driver assistance, comfort and operational efficiency. According to JOST, the approach allows fleets to progressively introduce new functions without replacing the underlying fifth wheel platform.
New ROCKINGER towing system and DCA One4All axle
JOST will also introduce a new generation of the ROCKINGER towing system, again based on a modular architecture. The system is designed to accommodate future safety, comfort and driver-assistance functions while maintaining compatibility with existing vehicle concepts.
Another premiere is DCA One4All, a common axle platform covering both disc- and drum-brake configurations. By using a shared architecture, JOST aims to give trailer manufacturers greater flexibility while reducing complexity in production, maintenance and spare-parts management.

Other products heading to Hannover include the TRIDEC TP-O low pendular suspension for heavy and specialised transport, as well as technologies from Hyva, which has been part of the JOST portfolio since 2025. These include Digital Tipping Solutions for construction and mining applications and the HPS hydro-pneumatic suspension system.
JOST will also showcase its KKS automatic coupling system, which uses camera guidance to automate the coupling process, and Hyva’s ePTO, designed to enable battery-electric commercial vehicles to perform tipping, lifting and other hydraulic operations without a conventional engine-driven PTO.
The company’s IAA display will be organised around four application areas – Transport & Logistics, Construction, Mining and City – bringing together products from JOST, Hyva, ROCKINGER and TRIDEC.
