Introduction
  YZ12 series vibratory roller is one kind of medium self-propelled vibratory roller. It is mainly used for the compacting work of infrastructure,sub-base and backfilling,which combined of sorts of materials. It is the ideal compacting machine for the building of high-level highway,airport,seaport,dam,and industrial yards.
  All of YZ12 series vibratry roller's main components and system are in line with international standard,with characteristics and constructions such as: three-gear stepless speed drive,three independant brake system,three-level vibratory reductions,as well as hydraulic conjoint steering,etc.
  YZ12 series includes three types: double drive and smooth drum,double drive and welded blocked wheel(DB as said in following table),as well as double drive and cover-shaped blocked wheel(DCB as said in following table). The changing work between the smooth and blocked drums is very simple.
