Bascule® Gates (Crest Gates)
Bascule® Gates are usually mounted on the crest of a dam and are hinged along the invert. There are several different types, but all lower to open and raise to close.
- Fully functional in ice conditions
- Can be fabricated in a number of sections joined in the field to a total of 200’ or more
- Ideal for flood protection/spillway control
Bascule® Gate Design
The Bascule® Gate design features a flat plate that is reinforced with vertical and horizontal members and is fitted with a single torque tube across the invert. The torque tube is supported by bearings along the invert edge of the gate. A hydraulic cylinder, cable drum hoist, or electric motor-driven cylinder is attached to the arm of the gate with a stem for operation.
The drawings presented here show a standard Bascule®Gate, and a typical construction arrangement.
