Functional Description Description ZF gearboxes GPT and GFA are drive components for mining ap- Both gearboxes - GPT and GFA - are characterized by high ro- plications and large construction machinery. bustness and reliability. This is - in addition to the design of the As successor company of the former Lohmann + Stolterfoht gears in the development and manufacturing quality - achieved GmbH the ZF Industrieantriebe Witten GmbH incorporates through the use of case hardened gears, and tempered and surfa- decades of know-how into the development and production of ce-hardened ring gears. In addition,...

Functional Description Gearbox design Disconnecting device Our gearbox design is based on long years of experience and If requested, some of the drive systems may also be provided with reflects not only the customary standard design regulations but a mechanical disconnecting device so that, if time is of essence, also satisfies operational strength requirements as per DIN 3990, the equipment can be towed without damaging the hydraulic ISO 6336, AGMA, GL or DNV. The output torque values indicated are short-term admissible peak torques meant for excavator travel drive applications. We offer application-specific...
