STR19P fully hydraulic vibratory road roller
Features
These rollers are all born of a rich history in research and development at STR. Though a much more simple machine than STRs hallmark bulldozers, rollers tend to focus more on such differentiating factors as the vibratory technology, user controls and comfort, and also exterior design,at all of which STexcels. In fact,STR researchers on this product line have long focused on the overall crucial factor of the machine’s longevity.
It shows, as STR rollers are besting the competition in China, and now making a name for themselves abroad.
The more inviting exterior designs and cabin ergonomics of STR rollers help create greater creature comforts and ease of controls for the operator.
This leads to getting more work done in a shorter amount of time.
The STR18M-2 is similar in use to the 14M-2 and the 18M/MP, yet sports a few extras such as imported ball bearings, a higher grade gearbox and a Cummins engine. The STR20M and STR20MP are similar to these, only larger. Same goes for the STR19P series.
