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.
