Hamm has been producing pneumatic tyre rollers with great success for over 50 years. Having revolutionised this machine type with its asymmetrical frame design around 8 years ago, the roller manufacturer HAMM is now set to present the next innovation in the pneumatic tyre roller market segment in spring 2018 with the GRW 280i.
The new GRW 280i pneumatic tyre roller is being launched with a range of basic weights (10 t, 12 t, 16 t, 18 t, 20 t, 24 t, 28 t). The machines are able to carry different quantities of ballast, depending on the basic weight. The external dimensions are the same for all variants. The “width over tyres” is 1,830 mm for all types. The machine has a maximum working width of 2,084 mm.
The GRW 280i is equipped with an environment-friendly, future-proof, water-cooled 4-cylinder engine with 85 kW output featuring diesel oxidation and nitrogen oxide reduction catalytic converter (DOC and SCR), as well as automatic regeneration. It complies with the requirements of EU Stage IV and US EPA Tier 4.
