Switch/Production Tamping Machine with Tamping Trailer

The Plasser GRM3000T is a heavy-duty, high-performance production and switch tamping machine. It is a multi-function tamping machine and has fully automatic track lifting, lining, and cross-leveling capabilities. These capabilities are specially designed for the stringent requirements of high density, high tonnage railways, shortlines and contractors. The machine’s compact design and weight allow for flexibility when transporting with flat cars or road trucks. The Plasser GRM3000T utilizes design concepts and components that have been well proven worldwide. The machine is constructed for ease of operation and maintenance.

Use of well proven components

The heavy-duty tamping units and rail clamps are well-proven components also used on machines of the DYNACAT and UNIMAT series tamping machines. During working operation and track travel, both axles of the GRM3000T are powered hydrostatically.

The GRM3000T is standard equipped with Plasser’s PLC system. Touch screen monitors allow quick access to all machine functions and the integrated diagnostic system assists the operator with effective trouble shooting. The sturdy control system works at temperatures of –40° F to 158° F, allowing operation in a wide range of environments.

During the machine’s development, particular attention was paid to ergonomic design. All operating controls are incorporated in the armrests of the operator‘s seat. The monitor showing the measured values is located directly within the operator‘s field of view. Moreover, diagnostics and service data can be accessed from the workplace.

Tamping Units

The Tamping Unit consists of four, 4-tool, non-synchronous tamping heads, housed in two separate frames with ballast consolidation performed via a vibratory hydraulic squeeze system. Each frame is laterally adjustable to allow complete switch tamping and splits into two, 4-tool sections. Each of the 4-tool, tamping unit heads can be individually controlled. This unique, “split head” system provides several major advantages over other switch tampers. Each unit is raised and lowered vertically instead of at an angle. This provides more uniform ballast compaction. Each 4-tool head concentrates ballast compaction near the rail base area where it is needed most. Unnecessary tamping at or beyond tie ends or center binding is eliminated. Individual control allows complete switch tamping with a minimum of horizontal tamping unit adjustment, thus reducing the amount of time required to tamp a switch. Tamping unit depth control is easily adjusted from the work cab to allow proper ballast compaction under varying track conditions. When using the machine as a production tamper, all four units are raised and lowered in unison, providing the same thorough tamping action for which all Plasser tampers are known. An automatic tamping unit lubrication system is installed with all Plasser Tampers.
