The boggle drive unit consists of double side helical and at the center a worm gear unit which is specified as double Hell-worm hear unit.

The boggle drive arrangement is used where bridge scrapper for lime stone is required to stack and for that this gear boxed are used at two different speeds.

• Shunting speed (High speed) – This is achieved through an A.C.Motor which drives worm gear unit through coupling (on RH side).
• Reclaiming speed (Low speed) – This is achieved through D.C. Motor which is driven Helical gear box and driving worm gear unit (onLH side).

Application : Bridge Scraper in the cement industry.
