Industry: Theatre
Application: Theatrical Rigging
Problem: Behind the scenes of the performing arts, lighting and other props are moved with theatrical rigging. This is a combination of many cables, winches, and drums. A traditional keyed mount was the means of connecting the drums to the shaft. Keyed mounts have the tendency to wear out quickly causing frequent and costly maintenance.
Solution: With Fenner Drives’ Trantorque GT Keyless Bushing, you can forget about worn keys, backlash, or wallowed keys! The Trantorque GT units eliminate the need for a key in the shaft which, in turn, eliminates the high cost associated with machining the keyway. Trantorque GT uses a single locking hex nut that allows for an easy on/off installation, as well as an extremely precise radial and axial positioning. All of Fenner Drives’ Trantorque products use a mechanical shrink fit to provide exceptional holding power. Since they are keyless, there is no fretting corrosion that is typically associated with a keyed connection.
