Abstract
An indexing apparatus for a track press machine moves and positions a track chain assembly into and out of the work area of the track press machine. The indexing apparatus includes upper and lower indexing portions, each having a powered drive mechanism for contacting and driving the track chain assembly. Fluid operated cylinders apply a force between the drive mechanisms and the track chain to prevent slippage. Fluid motors power the drive mechanisms to positively and continuously move the track chain. The indexing cycle is automatically controlled for fast and consistent work operations.
