Power Transmission Solutions for Marine and Offshore Oil & Gas
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.

When purchasing a complete turning gear system integrated with locking and braking from Altra, customers can consolidate 3 separate interfaces into one multi-functional solution: Turning ‘T’, Locking ‘L’, and Braking ‘B’, which enables customers to save dimensional space, decrease installation and maintenance time and reduce costs!
