Highlights

  • Continuous action production and switch track-tamping machine with high production rates
  • Two ties or single tie tamping operation based on tie spacing and position and machine model
  • Split head tamping unit design for turnout tamping with three-point auxiliary turnout lifting system achieving high working quality and lowering long-term maintenance costs
  • Optional tilting tools if required for special conditions
  • PLC touch screen controls for easy diagnoses and trouble shooting
  • Automatic Geometry Guidance System (AGGS) and Automated Tie Locating and Analyzing System (ATLAS)
  • Continuously moving machine frame reduced the impact on the operator during the indexing process of the tamper
  • Powerful lifting device for manipulating large concrete or wood-tie switches enhancing the taming quality in a switch and reducing the overall maintenance demand

The latest development in continuous action switch/production track tamping, surfacing and lining. The Unimat 09/4S series are all-in-one machines – continuous action production tamping, double split-head switch and interlocking tamping, and 50 mph travel capability. The 09/4S is available as a single tie tamper (Unimat 09-16/4S) or as a two tie tamper (Unimat 09-8x4/4S).

The Unimat series offered a number of benefits and features to increase machine productivity and worksite efficiency.  The operator’s cabin, travel cabins, power unit, main hydraulic components, and electronic systems are mounted on the continuously moving main frame. Satellite mounted tie tamping units and rail clamp are designed for high speed, continuous action production tamping. Double split, traversable, single tie tamping units provide complete switch tamping and combination rail clamp allows for switch and production work. The unique three-point Integrated Auxiliary Turn-out Lifting System excels in switch and interlocking work. The machine’s four rail tamping is capable of operating in switches and cross-overs..  A separate cab for switch and interlocking work allows better visibility and direct control over the track lifting operation while the sound insulated cabins provide for operator comfort and efficiency.

Integrated Auxiliary Turn-out Lifting System

The Plasser Integrated Auxiliary Turn-out Lifting System consists of a hydraulically-operated, telescopic, auxiliary-track-lifting clamp mounted on each side of the machine adjacent to the main track-lifting clamp. These clamp assemblies provide a precisely controlled lift of the outside turn-out rail during switch-tamping operations. The auxiliary clamps are controlled from the operator's cabin, with the amount of lift determined automatically by the machine's electronic surfacing and cross-level control system. The use of the system during switch tamping operations greatly reduces stress applied to rail fasteners, ties and rails, and applies uniform lift at three points in the long tie areas of switches. The need for cumbersome, manually placed track jacks, hydraulic hose reels, and the related maintenance cost is eliminated. Labor costs can be reduced; and safety hazards associated with the placement and operation of conventional track jacks during switch-tamping operations are eliminated. Due to the system's integrated design and its lifting function that coincides with main machine operations, overall performance is greatly enhanced.
