From lightweight materials to solutions for alternative powertrains, let’s see how JOST supports greener mobility

Under the umbrella brand of JOST, we now have quite a comprehensive range of products coming from the different brands belonging to the JOST World. To make some examples, JOST includes fifth wheel couplings, landing gears, and axles, ROCKINGER specialises in towing hitches, drawbar eyes and drawbars for transporters and trucks; TRIDEC provides steering systems and axle suspensions for trailers, while HYVA, acquired earlier in 2025, is a leading producer of front-end tipping cylinders and also offers underbody and double-acting cylinders, lifting systems and waste handling solutions.

JOST towards greener mobility in freight transportation

One of JOST’s major efforts is put in making the commercial vehicles more environmentally friendly by providing technologies supporting electric or hybrid engines as well as developing light-weight materials to improve fuel efficiency and reduce emissions. Additionally, JOST ensures advanced recycling solutions for end-of-life components. All these innovations aim to minimize environmental impact, decrease carbon footprint, and promote sustainability within the transportation sector. Let’s see how, in terms of very concrete product and solutions.

First of all, the new aluminum drop leg FA027 from JOST is particularly aimed for users of tippers, tankers and silo vehicles, and wherever low weight is a requested. While its “big sister” Modul CA is intended for frequent saddlers, the new FA027 aluminium drop leg is aimed at users who saddle less frequently. As a result, an average of 30 to 40 kilograms can be saved on each semi-trailer, which can be directly converted into additional load. If the extra load is not utilised, users also benefit from lower fuel consumption. As you would expect from JOST, the materials and components used meet the highest quality standards and are maintenance-free, which guarantees a long service life.

JOST for advanced and more sustainable lubrication

The second generation of the LubeTronic 1Point combines sustainability and user-friendliness. Featuring a refillable cartridge, the unit allows easy, tool-free maintenance and reduces waste over its life cycle. Filled with biodegradable high-performance JOST lubricant, the system ensures excellent lubrication and long service life for fifth wheel couplings and other components. On the other hand, JOST high-performance and completely biodegradable lubricant for fifth wheel couplings JHS 2020 B is suited for the manual lubrication of all fifth wheel couplings, king pins and ball bearing turntables. The key features of the lubricant are its complete biodegradability, minimal application requirements, temperature resistance, high adhesion on metal surfaces and minimal water absorption.

Weight-optimised axle and e-axle solutions

Reducing emissions, protecting resources and maximising efficiency were the key aims when developing the lightest axle in its class. The optimised structure of the entire axle reduces the trio weight by 51 kg. In combination with the optional Weight Optimiser 27, the air bellows support with a lightweight aluminium tail end structure, further weight savings of 27 kg. The highlight of DCA WEIGHTMASTER PLUS is its wheel head with optimised weight, wear properties and performance. This includes the new DCA X7 brake, the lightest brake in its segment. The aim during its development was to achieve ideal interplay between the brake disc and lining, thereby reducing emissions while maximising the payload and performance.

With the e-axle, JOST offers a cost-efficient and modular system that can be used flexibly for battery-electric trucks as well as for vehicles with conventional combustion engines in a resource-saving manner. Thanks to its lightweight and compact design, the e-axle enables flexible use in a variety of applications: from light distribution transport and short-haul routes to long-haul operations with the requirement for a long range to heavy-duty transport for traction support during start-up maneuvers. The emission-free drive ensures a reduction in CO2 emissions in conventional diesel vehicles and increases the range of the vehicle combination, regardless of the type of drive. In field testing, over 20 per cent was achieved. Finally, the modular low-voltage system of the JOST E-Axis with an operating voltage of 48 V and a basic output of 90 kW offers a safe and maintenance-friendly product.

JOST CSA and TRIDEC EF-S: Command Steer Axle with electronic steering system

Following the successful market launch of the CSA with the 9-tonne version, a 10-tonne axle has been added to the portfolio. Like the 9T, the CSA 10T can also be used in all conventional steering systems whether mechanical, hydraulic or electronic. It impresses with outstanding performance characteristics and, in particular, the lowest roll radius. This has a positive effect on the actuation force, which is up to 70 per cent lower than that of comparable axles as a result.

The JOST CSA is perfectly tailored to TRIDEC-brand steering systems: the TF mechanical system, the HF and HF-E hydraulic systems and the EF-S electronic steering system. Up to three JOST CSA axles can be used. The steering angle can be easily adapted to the available space for installation and the required maneuverability.

Finally, two more products play a role in the #jostgreen vision. The JOST DCA-L7-2 disk brake impresses in terms of reliability, ease of servicing and weight. Both trailer manufacturers and hauliers benefit from the lower weight, higher payload, optimised ease of servicing and maximum quality and reliability. The swivel axle suspension TRIDEC TP-O Low, which especially fits the high volume low-bed market in Europe, offers the lowest ride height with 12 tonnes per axle line, combined with a greater steering angle than any other suspension solution.
