Digital Turning Tool

DTT Components

Hydratight's Sweeney brand of Digital Turnover Tool (DTT) is designed to improve the efficiency of aircraft engine borescope inspections by automating the process of rotor shaft positioning.

The DTT provides greater efficiency than manual turnover by eliminating the need for a second technician to rotate the engine shaft. The DTT also provides a constant rotation speed, overshoot-free operation and automatic blade counting, all of which are unattainable with manual turnover.

There are three major components to the DTT system: the controller, the power unit, and the drive unit. All engine inspection functions reside on the controller, with a second user interface housed on the power unit.

The Digital Turnover Tool makes borescope inspections much more efficient. The inspector can control the engine rotation with the push of a button making it a one person operation.

A full product demostration can be arranged, on-site, by our fully trained representatives, please call for details.
