Noise Behaviour:

New concepts were applied to clearly improve the noise emission of the gear units
Designing noise-absorbing case
Achieving exceptionally large contact ratios
All the gears have been grinded .

Thermal conduction:
Gear units not only have a high efficiency but also have a favorable thermal conduction

Through enlarged housing surface areas;
As large fans incorporating a new type of air conduction fan cowl are being used
Selection of gear unit is based on a lower maximum oil temper ature .By that ,the operational
reliability will be increased and the cost of maintenance reduced due to longer oil change intervals

Storing:
Gear units have been designed according to a new unit construction principle, which reduce the variety
