Trailer PRONAR T663/2 & T663/2 SILO

Trailer PRONAR T663 / 2 is a three-way tipper trailer that can serve a similar purpose as two-axle trailer. However, due to  tandem suspension which not only distributes the load on the wheels of the trailer but also on the  tractor hitch,  it is perfect  to work in difficult terrain, when  dealing with soft  ground, including  green areas and work related to  municipal services.

PRONAR T663 / 2  Trailer  is available as SILO version “T663 / 2 SILO”, which has sidewalls increased by 500 mm , including the hydraulic tailgate which make it more effective . High quality and multifunctionality will satisfy every demand.
