These single speed transmissions consist of planetary set up, driven by a sun gear. There are two reaction brake banks within the housings. One engages the forward position and the other engages the opposite reverse direction. When either one is clamped down by force of the cam, forward or reverse will then be engaged.

The unique dual brake band design allows for immediate shift on the fly direction control from the forward to reverse, even under a full load, since the input and output shaft gearing is always in constant mesh with each other.

​

Our rugged designs provide for a prolonged life even in the harshest applications.
