Overview
The BOMAG CR 820 T is an 8-foot (2.4 m) tracked highway paver engineered for precise, full-width paving and flexible operation. Improved operator platform, dual swing-out stations with SIDEVIEW, FRAME RAISE and the Stretch® 16 hydraulically extendible screed deliver consistent mat quality and efficient site workflows.

Key values

• Emission stage: Stage IV / TIER4f
• Weight: 16,511 kg
• Working width (min-max): 2,400 - 4,600 mm

Primary features

• SMARTRAC auto-tensioning maintains track chain tension to extend track life and reduce daily maintenance
• Integrated fume-recovery system directs asphalt fumes away from the operator station to minimise exposure
• FRAME RAISE improves ground clearance for manoeuvring and loading while enabling fine tuning of the head of material
• Twin counter-rotating augers reblend the asphalt mix to eliminate thermal segregation and correct cold spots before paving
• Dual swing-out operator stations with SIDEVIEW provide four swivel angles for unobstructed visibility
