2 JOST Trailer Axles Innovation meets experience JOST is a corporate group that has been a global leader in the production of systems, modules and components since its foundation in 192. On the african market it has been present for more than 0 years. In 201 JOST expanded its portfolio with Axle Systems, formerly Mercedes-BenzTrailerAxleSystems. With this Prime-Series, JOST offers weight-saving trailer axles for a wide range of uses. Innovative products from the axle series DCA and the use of disc brakes revolutionised the trailer market in a long-lasting way. JOST and the experts from MercedesBenz have now developed an addition to the existing axle programme, especially for Africas toughest environment: The Standard-Series, a robust and high performance running gear. The new drum brake axle is a very durable and delivers optimum performance under cost-effective aspects. Furthermore it is especially easy to maintenance and hte spare parts are widely available through JOST s worldwide network. Standard Prime

7 The special equipment for Standard and Prime Series Preparation for tyre inflating system Preparation of the DCA Family axles for deployment of a tyre inflating system on the trailer enhances the vehicle s operational safety and availability. Threaded through-bores in the axle journals serve as compressed air connections for a tyre inflating system, which prevents excessively low tyre pressure. Longer service lives for the tyres, less rolling resistance for the trailer and an attendant reduction in fuel consumption for the truck/trailer combination lower the required scope of maintenance work and improve the vehicle s economic efficiency. The Twin Lifts The Twin Lifts are suitable for all applications with medium and high ride heights. They are characterised by their robust construction and low weight. The Twin Lifts reduce effort to a minimum even when retrofitted and are geared towards special usage cases. The Wipper Lift Wipper Lifts are designed for use in mega-trailers and other vehicles of a low ride height. They offer maximum ground clearance thanks to their shallow and stable construction, even for vehicles of a low ride height. Thanks to their lifting power, the WPs are suitable for use with both the DCA family and the DCA Steermaster. Hubodometer Hubodometers are used to calculate distance driven, independent of the truck, for all types of wheeled vehicles. They are characterised by a hermetically-sealed measuring unit. This prevents the formation of condensation and makes them maintenance-free and tamper-proof. The mileage is shown as a six-digit display in km and can be set to miles on request.

8 DCA Family Durable Compact Axle Prime Series The fully-modular axle construction opens up unlimited possibilities with a minimal number of different parts. For you, the customer, this means fewer replacement parts, lower storage costs and, last but not least, lower life cycle costs thanks to unmatched quality. The beam The compact axle beam gives the axle family the name DCA Durable Compact Axle. Integrating all the axle functions creates a compact axle housing that is extremely durable and lightweight thanks to its innovative construction. The axle housing integrates the trailing arm, axle tube, brake flange and axle journal, forming a perfect unit. The wheel head A robust construction for 19." or 22." wheels that has proven itself millions of times. The optimal heat dissipation ensures a very long lifespan for the brake discs, brake pads and storage. The brake discs made out of a wear-resistant alloy and the wearing parts are structurally identical to those of Mercedes-Benz lorries. The compact bearing Maintenance-free thanks to the use of state-ofthe-art compact-bearing technology that has been proven a millionfold. The hanger bracket With three retaining brackets each in some cases also optionally available in stainless steel the DCA Family in combination with the appropriate air bellows supports makes possible all driving heights from 21 mm to 3 mm, from megatrailer to tipper. The tailend The DCA family can be implemented with standardised, weight-optimised or application-specific tailends, covering all areas of usage. The L7 disc brake The new DCA L7 disc brake for 22." use was designed to be weightsaving for maximal loading capacity. Optimised for the DCA family, the disc brakes save more than 8 kg per axle compared to the current systems.

9 DCA Weightmaster The DCA Weightmaster is the core member of the axle family. Its low weight from just 390 kg, depending on which version coupled with its durability, the advantage of fewer components (due to its monocoque design) coupled to the maintenance-free compact bearings, makes it ideal for use in the European transport industry. With its modular design, it is compatible with nearly all trailers, from platform semitrailers, curtainsiders, tippers, tankers and bulk distribution. The DCA Weightmaster is compatible with 19. or 22. wheels.

This special-purpose axle and suspension is for high-volume road haulage applications, and vehicles that require a long axle travel, this range is based on the innovative and proven components of the DCA Family. Despite the low ride height, loading docks can be reached for the purpose of loading and unloading.

10 DCA Airmaster As the world s only axle that stores compressed air for the brakes and air suspension in the axle housing, the DCA Airmaster is able to dispense with the conventional compressed-air tanks that appear on trailers or semitrailers, thereby freeing up space beneath the trailer as well as reducing weight by up to 0 kg. The DCA Airmaster paves the way for the introduction of trailblazing vehicle concepts. TE4-8N TE-8L TE-8K TE-8N Permissible axle load Wheel offset ET 120 Wheel track, spring centre Suitable for all standard vehicle versions Air bellows diameter (Ø) 300 mm; 360 K; 360 L Ride heights 22 3 mm Lift range Depending on version Min. wheel size Brake SN 6 DCA L7 SK7 SN 7 Brake disc diameter (Ø) 377 mm 430 mm 430 mm 430 mm Weight* 381 kg** 389 kg 397 kg 416 kg Type of bearing Maintenance-free cartridge bearing Paint system Cathodic dip priming Tyres Single Storage volume Up to 40 l per axle ** Additional weight saving of up to 0 kg per vehicle due to absence of compressed-air tanks. DCA Steermaster An ideal addition to the DCA Family. With a steering angle of max. 16 degrees, it negotiates bends with consummate ease, while the lightweight design allows high payloads. In addition, the steering axle reduces the truck s tyre wear and fuel consumption. Like the other axles in the family, the DCA Steermaster is based on the tried-and-trusted components of the DCA modular system and, therefore, offers the versatility you expect when it comes to meeting your transport needs.

11 DCA Railmaster The new DCA Railmaster is designed for use in combined roadrail-sea transport. If a semitrailer is lifted by crane, conventional air bellows can be damaged while the vehicle is being set down. That is why the air bellows of the DCA Railmaster consist of two interlocking components which can separate during lifting or driving without air and ensure the optimal position of the air bellows when the semitrailer is set down. TE4-8N / TZ4-8N TE-8L / TZ-8L TE-8K / TZ-8K TE-8N / TZ-8N Permissible axle load Wheel offset ET 120; ET 0 Wheel track, spring centre Suitable for all standard vehicle versions Air bellows diameter (Ø) 300 mm Ride heights 22 2 mm Lift range Depending on version Min. wheel size Brake SN 6 DCA L7 SK 7 SN 7 Brake disc diameter (Ø) 377 mm 430 mm 430 mm 430 mm Weight 397 kg 410 kg 418 kg 436 kg Type of bearing Maintenance-free cartridge bearing Paint system Cathodic dip priming Tyres Single DCA Pavemaster The DCA Pavemaster unites an optimised tail end design especially for tippers in road finisher application. The DCA Pavemaster has been built to the highest standards to meet the specific demands of road construction. With the new design we were also able to reduce the weight of the DCA Pavemaster by up to 12 kg per axle.
