Nuttall designs and manufactures primary and secondary gear drives used on all types of moveable bridges including bascule lift, swing, and vertical lift. Custom heavy-duty Nuttall gearboxes are also used on dam and spillway flood gate drivetrains. Nuttall technicians utilize the latest testing techniques and technology including laser alignment of all drivetrain components, twin dynamometers, and massive, custom-built test stands which allow two 15,000 lb. gearboxes to be mounted and tested back-to-back on inclines up to 75 degrees.
