Engine-Dependent PTOs for Automatic and Manual
Transmissions

High useful torque is attractive for mobile cranes, concrete
pumps, fire-fighting, and special vehicles
The engine-dependent PTO named NMV is installed as a sandwich
between the vehicle engine and transmission.
With this modular system, ZF replaces and extends the proven
engine-dependent PTOs which have so far only been available for
the commercial vehicle manual transmissions Ecosplit and
Ecomid. This modular design allows to combine the NMV also with
the automatic and fuel-saving transmission systems AS Tronic and
AS Tronic mid.
Engine-dependent PTOs are particularly attractive for applications
which require high torques for their auxiliary power units, such as
concrete pumps, mobile cranes, airport crash tenders, or drilling
and winch drives.
The new NMV is generously dimensioned with an output of 316 kW
and a maximum torque of 2 000 Nm. It is available for different
installation positions and with two different ratios. Moreover, it has
a cooling circuit of its own. Independent of the drive clutch being
closed or open, the NMV has a constant engine output but can still
be decoupled with powershifting being possible. For the first time it
is also possible to combine the automatic and fuel-saving
transmission systems of the AS Tronic model range with an NMV.
An SAE interface enables the PTO to be mounted to all common
commercial vehicle diesel engines.
Many special vehicles depend on transmissions which can be
combined with such an engine-end PTO, for example concrete
pumps, sewer cleaning vehicles, airport crash tenders, and mobile
cranes. All of these applications require a rather high output for
operating their pumps. With cranes, for example, there is a linear
correlation between torque, hoisting capacity, and setup times.
With the new engine-dependent PTO, previous setup times are

reduced by half – a significant contribution to increased costeffectiveness in operation.
Another advantage of ZF's engine-dependent PTO is the fact that it
is designed for longer operating times. This is also ensured by a
separate oil and cooling circuit. A powerful torsional vibration
damper, which balances the shocks caused by the irregular
rotation of the crankshaft at the engine output, is also important.

AS Tronic and AS Tronic mid as well as the current Ecosplit
and Ecomid transmissions.
