Turning, Locking & Braking System

A Superior Solution From A Single Source

The Twiflex system comprises a Turning gear, Locking device, and shaft Brake (TLB) together with a power unit (e.g. Hydraulic Powerpack) and a control panel for local operation of the system close to the equipment. TLB is available as a continuous turning option as shown or as an indexing system using a simple hydraulic ‘push-pull’ arrangement with the brakes and brake disc to inch the propeller shaft for maintenance and accurate alignment. For a more cost effective solution, a simple manual option is also available for this purpose.
