I see that all models have been replaced with “R” suffix machines, what is the difference?
The mechanical and visual aspects of our machines remain unchanged, electrically they are very different. The LT-1B and LT-2A used a full wave speed control, braking resistor, special reversing switch, and control relay to provide rapid reversing. This was a reliable system that worked very well. All “R” models use a regenerative speed control that eliminates the need for relays of any kind as well as special reversing switches. It provides faster start stop times, and as a result faster direction changes. The speed is more accurately controlled, and all speed and direction controls are low voltage resulting in longer life. All “R” models come with a totally enclosed 1/2 horsepower Baldor motor that provides more power and quieter operation.
