Road surface rolling machine roller - has burners for heating and out-of-balance shaft for vibrating roller

摘要

The road rolling machine has heated and vibrated rollers. The heated road roller need not be wetted with water because the hot roller does not pick up any bitumen from the road surface. The roller (2) which rotates on an axle (1) is divided by a ring (3) into concentric sections with annular chamber (4) into which hot gases are blown from the burners (5). The stiffening ribs (6) are arranged so that the burners are optimally utilised. The burners are held on brackets (8) on the frame (7). The roller is vibrated by a rotating shaft (9) with out of balance mass.
