The GGT 275 gearbox series has undergone a major upgrade to be designed again for maintenance staff vehicles.
In this case, the biggest advantage is its
new modularity. The GGT 275 series of
gearboxes allows the use of several fixed

gear ratios without changing the size of
the gearbox housing. It is also a two-speed spur gearbox intended for maintenance vehicles. Three different fixed gears and two different motor connections
can be used. The gearbox series has been optimised for very low operating speeds at full load (<1 km/h). It is also important to note that the gearbox is
available in two versions, one directly
mounted on the axle or a suspension
version with a hollow shaft in the gearbox and a clutch on the axle.
The gearboxes can be equipped with
a unique remote condition monitoring
system developed by Gmeinder. GGTGearSaver® is a unique system using only
one comprehensive sensor that is capable
of monitoring oil operating temperature,
relative humidity, oil level and ferromagnetic particle contamination. The system
brings a completely new concept of preventive maintenance to the customer. It
reduces maintenance costs and minimises
the risk of a fatal gearbox or whole drive
failure.
Hronov-seated Wikov MGI focuses on
the use of artificial intelligence in serial
stress-free testing of gearboxes or its involvement in the evaluation of measured
data in the WiGuard® remote diagnostics
system.
The development project for the use of
composite materials in the production of
gears looks very promising.
