New aluminum drop leg FA027 from JOST: lightweight and powerful

With the FA027 aluminum drop leg, JOST is expanding its landing leg portfolio in the weight-sensitive transport segment. Like its “big sister” Modul CA, the aluminum drop leg is particularly aimed for users of tippers, tankers and silo vehicles, and wherever low weight is a requested. While the 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. This means that an average of 30 to 40 kilograms can be saved on each semi-trailer, which can be converted directly into additional cargo. This means maximum turnover on every journey. If the extra load is not utilised, users also benefit from lower fuel consumption. With a static load of up to 24,000 kg per set, the FA027 offers the ideal combination of high robustness and extremely low weight. We focus on lightness without compromising on stability or safety. 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.

Sustainable lubrication: LubeTronic 1Point with refillable cartridge

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.

JOST high-performance organic lubricant for fifth wheel couplings

Conventional connections between truck and trailer are made of steel and need to be lubricated regularly to avoid wear and damage. JOST was the first manufacturer to introduce a completely biodegradable high-performance lubricant for its fifth wheel couplings and has been able to further develop the mixture over the last few years to meet customer-specific requirements. The lubricant 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.

DCA WEIGHTMASTER PLUS: new weight-optimised axle

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 are possible in the trio. 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.

The PLUS series of DCA axles offers benefits for all trailer applications. That is why it is not limited to the WEIGHTMASTER series. The new features will also be available for DCA AIRMASTER, DCA STEER-MASTER, DCA PAVEMASTER, DCA MEGAMASTER and DCA RAILMASTER.

E-Axle: Save while driving

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 e-axle can be modularly adapted to different application requirements and offers a cost-effective way to make transport fleets more sustainable. 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.

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. Regenerative braking put less strain on mechanical brakes, which reduces the need for servicing the brakes.

The system can be operated with conventional trailer tires.

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

Tight depots, narrow city streets and a 16.5-meter-long trailer that needs to be steered safely – all challenges that push conventional axle systems to their limits and demand a command steer axle. 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. Additional batteries are rendered obsolete and there is greater flexibility when designing steering systems. The low space requirement of the CSA is unparalleled, enabling smaller mud guard designs and thus wholly new vehicle designs, even when space is tight.

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.

DCA-L7-2 disc brake: weight-optimized brake caliber design

JOST has once again optimised the weight of its tried-and-tested DCA-L7, allowing the user to pull 3 kilos more payload per axle. The JOST DCA-L7-2 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.

TP-O Low: swivel axle suspension

The swivel axle suspension TRIDEC TP-O Low is opening up a new market for independent trailer manufacturers. The TP-O Low especially fits the high volume low-bed market in Europe. With suspension travel of 600 mm, the TP-O Low offers the lowest ride height with 12 tonnes per axle line, combined with a greater steering angle than any other suspension solution.
