The modern St Marys factory has the capacity to build the entire Plasser range of products, including even the largest machines.
The factory is fully self-contained with minimal dependence on sub-contract work. Virtually all work is integrated within the one complex, uniting several engineering disciplines:
- Heavy structural steel fabrication
- Sheet metal fabrication
- Electrical manufacture and installation
- Hydraulic and pneumatic installation
- Hydraulic cylinder manufacture
- Fitting and assembly
- Testing and calibration
Numerous machines have been developed and adapted specifically for Australian railways and local conditions for narrow- standard- and broad gauge, as well as special machines for the 610 mm gauge sugar cane railways.
