The Plasser American Corporation 08 32 Unimat 4s is a fully automatic tamping machine. The 08 32 Unimat can be used to tamp, lift and line switches or plain track. The 08 32 Unimat 4s utilizes the proven Plasser technology along with the AGGS computer geometry system to give superb quality track work. The 08 32 Unimat 4S uses a 32 tool split tamping unit system that allows the independent tamping of inside and outside the rail or any combination there of. The tamping units can also be traversed side to side and telescoped outside the frame, and rotated to allow for the most complete, accurate tamping of a switch. The rail lifting and lining is done with a rail hook and roller clamp assembly. The 08 32 Unimat 4s also has an auxiliary third rail lifting clamp that will allow the lifting of the turnout rail in conjunction with the main lift to eliminate the need for helper jacks to prevent over lifting of the main rail.
