Bridge-Mounted Drive

Bridge-Mounted Drive

Used in industrial, municipal, and mining clarifiers and thickeners

The DBS Bridge-Mounted Drive is a low-speed, high-torque, totally enclosed gear drive with positive overload protection. The drive unit has a central output shaft to drive the rakes, and is supported by a bridge completely spanning the tank. It is typically used on tank sizes from 10 to 100 ft (3 to 30 m) in diameter.

The main gear and pinion are made from forged alloy steel designed for 20 years of life (calculated per AGMA 2001-D04) inclusive with a 10-year warranty. Each unit is designed for minimum maintenance with a permanently lubricated intermediate reducer. The design does not have lower pinion bearings, eliminating a common source of drive failure and increasing reliability.

An accurate torque gauge is integrated into every unit and can be calibrated in ft-lbf, N-m, or any units desired. This model also includes alarm and cutoff switches and maximum torque limiting via shear pin or pressure relief valve.
