Servo Tractors
Knight’s Servo Tractors are designed to accurately locate, push, tow, lift and position loads from an overhead rail system. Tractors significantly reduce the push/pull forces as well as the energy to sustain movements.
These Servo Tractors are equipped with Knight’s (IAD) Intelligent Assist Device Servo Technology, allowing them to provide controlled transfers of workloads with speed and precision. They can be programmed to automatically or manually move and stop the runway at intended locations with repeatable accuracy while lifting loads at the same time; thus eliminating unnecessary operator motions. They can also be programmed for assembly line speed synchronization.
The KST4000 Rack and Pinion 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.
