ZF

ZF Industrieantriebe Witten GmbH is the industrial gearbox business of ZF Friedrichshafen AG, based in Witten, Germany. It traces its history to Lohmann + Stolterfoht, whose large-gear business passed to Bosch Rexroth in 2009 and was taken over by ZF in 2015, and it draws on more than 100 years of heavy gear engineering.

For marine and offshore markets the Witten business supplies large reverse-reduction propulsion gearboxes (the former Navilus range), flexible couplings and clutches, and drive gearboxes for offshore equipment: GPV gearboxes for jack-up systems on drilling platforms and supply vessels, GFB swing drives for positioning on-board cranes, and GPT-W winch drives for lifting heavy offshore components. Couplings and clutches are offered as a separate product family with a long marine record.

The unit is distinct from ZF Marine in Friedrichshafen, which supplies transmissions, thrusters, propellers and controls for smaller commercial vessels and yachts. Customers include deep-sea merchant ship, offshore and naval builders.
