Towbars

Centrally mounted, semi-undermounted and undermounted towbars for centre-axle trailers. Towbars can be fitted at intervals of 25 mm.

Fuel tanks

Aluminium or steel tanks in volumes from 150 to 900 litres. Maximum fuel volume is 1,480 litres for a 4×2 tractor.

AdBlue tanks

Plastic. Volumes from 32 to 90 litres. The AdBlue pump is integrated in the AdBlue tank module.

Fifth wheels

Certified installation permits up to 36 tonnes load. An ISO fifth wheel with L-shaped profiles at different heights is included in the range, offering considerable freedom of choice. The flange-mounted fifth wheel is a low-weight variant since it does not require any attachment plate. The fifth wheel’s height above the chassis is from about 140 mm. Integrated lubrication and trailer connection indicator is available as option for specific variants.

Volvo Dynamic Steering

Active steering system with torque overlay. Delivers more steering force at low speeds, reduces steering kicks and keeps the steering wheel straight forward when braking on split friction. The steering wheel returns automatically to neutral position both when driving forward and when reversing.

Available for tractors and rigids 4×2, 6×2, 6×4, 8×2 or 8×4 with single front axle.

Tag axles

Available in several configurations – fixed with single or dual wheels, self steered or actively steered. Axle load: 7.5, 9.5 or 10 tonnes.

Pusher axles

Available in fixed and actively steered variants for both tractors and rigids. Axle load: 7.5 or 9 tonnes.


Brakes

Volvo EBS (Electronically controlled Brake System) disc brakes are available with EBS Standard and EBS Medium program packages for tractors and rigids. ESP is available for tractors and rigids with 4×2, 6×2 and 6×4 drive. In this way Volvo can offer ESP on virtually all ADR applications and EMS combinations. The brake range also includes Volvo Z-cam drum brakes with ABS (Anti-lock Braking System).

EBS MEDIUM
In addition to the EBS Standard package, EBS Medium adds the following features.

EBS Status Control
EBS status monitoring via the TEA2+ vehicle electronic system and Volvo Tech Tool.

Hill Start Aid
The brakes are only released once there is sufficient engine torque to propel the vehicle forward.

Lining Wear Analysis
Brake lining warning – calculates the remaining mileage available with the current brake linings.

Automatic Parking Brake Release
The parking brake is released when the driver pushes the accelerator pedal and a gear is selected (only I-Shift gearbox).

ADDITIONAL OPTIONS
In addition to the program packages there are the following options:

Stretch Brake
Enables the driver to request pulse braking of the trailer. The brake is then automatically activated and the risk of jack-knifing is minimised. Only for rigids.

ESP (Electronic Stability Program)
The brake stability system applies the brakes individually on each wheel, thereby providing stability for the entire vehicle combination and counteracting jack-knifing, rollover and trailer swing. ESP fulfils the legislation of Electronic Vehicle Stability Control.

Emergency Brake Light
When panic braking from speeds above 50 km/h, the brake lights flash with four flashes per second.

Hydraulic retarder
Gearbox-mounted compact retarder with a max effect of 440 kW.
