Single Phase, Rack and Pinion Servo Tractor, 4000 lb capacity

Knight Global's KST4000 Series Rack and Pinion Servo Tractors is a stand alone tractor that is designed to push, tow and position loads that are suspended from a trolley on an overhead rail system. Tractors significantly reduce the push/ pull forces as well as the energy to sustain movements. Knight's KST4000 Series Servo Tractors have Knight's (IAD) Intelligent Assist Device Servo Technology incorporated into their design allowing them to provide controlled transfers of workloads with speed and precision. Rack and Pinion Tractors can be programmed to automatically or manually move and stop the runway (X Axis) or bridge (Y Axis) at intended locations with repeatable accuracy; thus eliminating unnecessary motions. (Knight Servo Tractors can also be programmed for assembly line speed synchronization).

The KST4000 Servo Tractor offers a continuous contact non-slip rack and pinion design. This continuous non-slip design allows for a more accurate positioning of the load. Movement of the Servo Tractor is controlled by a two speed pendant, and can be programmed for multiple positions.
