Engine: The paver finisher is driven by a water cooled diesel engine. For further de-
tails see the technical data and the engine's instruction manual.
Various engine variants in different emission classes are available as options.
Stage IIIa / Tier 3 (o): There is no separate exhaust aftertreatment for this engine
type when used in countries without specific regulations.
Stage IV / Tier 4final (o): The engine complies with the latest emissions standards
and helps to reduce diesel consumption and improve the working environment.
The exhaust gas aftertreatment system consists e.g. of a diesel oxidisation catalytic
converter (DOC), an SCR catalytic converter (Selective Catalytic Reducer) and
®
an AdBlue
/ DEF injection system.
The emission of exhaust gases which are harmful to the environment and health is
significantly reduced.
Stage V (o): The engine complies with the latest emissions standards and helps to
reduce diesel consumption and improve the working environment.
The exhaust gas aftertreatment system consists e.g. of a diesel oxidisation catalytic
converter (DOC) + a diesel particulate filter (DPF), an SCR catalytic converter
®
(Selective Catalytic Reducer) and an AdBlue
/ DEF injection system.
The emission of exhaust gases which are harmful to the environment and health is
significantly reduced.
Traction unit: The front axle is a tandem swing axle. As the wheels are not mounted
on non-uniform lifting arms, the second front wheel is subject to a heavier load on the
shorter lifting arm.
This solution provides increased steering and load-bearing capabilities, especially on
soft grounds. The tyres are solid rubber tyres at the front axle and large, tubeless,
pneumatic tyres at the rear axle (water filling - o).
With additional front-wheel drive, the second front axle or both front axles can be en-
gaged as additional drive axles.
Hydraulic system: The diesel engine drives the hydraulic pumps for all main paver
finisher drives via the attached distribution gear and its auxiliary drive shafts.
Travel drive: The continuously adjustable travel drive pumps are connected to the
travel drive engines by means of high pressure hydraulic hoses.
These oil engines drive the drive wheels via planetary gears.
The multi-stage planetary gear covers the various driving ranges and the braking
function.
