Description

General

Hydrostatic HYDROTRAC GFT drives units are the perfect transmis-sion solution for wheeled or track-laying vehicles and othermobile equipment. Moreover, they are the best choice for allapplications where something is to be moved, rotated, slewed

etc. Various design versions attest to the versatility of these gearunits.

As a result of their extremely compact shape HYDROTRAC GFTgears lend themselves also to space-critical uses.

The use of case-hardened gearwheels and nitrited annulus

gears in conjunction with a high manufacturing quality standard makethe drive unit outstandingly enduring and safe to operate.

Gearteeth design is based on computer programs to ensure maxi-mum safety.

The drives feature an optimum total efficiency achieved by usingplug-in type hydraulic motors and exclusively antifriction-type bearings.The gear units described in this bulletin are subject to con-stantupdating and technical advancement. To suit thespecif-ic needs of our customers with respect to dimensions andoutput further variants can be made available on request.

We are prepared to give advice and provide assistance when-ever needed, even in the project stage, to find the most ap-propriateapplication solution for you.

Brake

The standard supply scope includes a spring-loaded,hydrauli-cally released multiple-disk parking brake arranged on the in-put side.

TBr sta. min = 1 T1 (input torque)

The holding torque multiplies as a function of the selected transmis-sion ratio, The multiple -disk parking brake is not a dynamically op-erating service brake.

Description

Sealing

Tightness of the joint between stationary and rotating gear-box sec-tions is ensured by means of a high-grade axial mechanical seal soas to prevent moisture and dirt entering the gear unit even underextreme operating conditions.
