Top Roller/Upper Roller/Carrier Roller
The top roller supports the wheels of the top track and plays the role of supporting the top track shoe, which can prevent the track from hitting.
The upper roller also makes the track have a certain degree of tension, and the verticality of the track does not exceed a certain limit, so as to prevent the track from drooping too much.
Moreover, the carrier roller can reduce the running resistance of the track to ensure the smooth running of the track.
The top roller is composed of wheel body, shaft, copper sleeve, end cover, floating oil seal and other parts, and its structure is the same as that of the bottom roller.
The upper roller models currently being produced in the factory are: Fuwa QUY50 and QUY70; Hitachi CX1000, CX900HD and KH180-3; Manitowoc 4000 and M85; Liebherr LR1160, LR1280 and HS885; Demag CC2500; Zoomlion QUY180, QUY70 and ZCC750H; American 7250; IHI CCH700 and CCH2500; Kobelco P&H315, '7055-1, CK1000-II and CK1200.
