Operating weight
12,000kg
A 12-tonne hydrostatic single drum roller from Caterpillar (Qingzhou) — dual amplitude and frequency, 45% gradeability, canopy as standard with a sealed cab and air conditioning optional.
Turbocharged with air-to-air charge cooling and a modular cooling package rated to 49 °C ambient, so the machine keeps working in tropical and Gulf-coast heat.
33/30 Hz and 1.8/0.9 mm: high amplitude for sub-base rock fill, low amplitude for asphalt courses and thin layers.
Variable-displacement piston pump and motors drive the drum and the rear axle independently of engine speed — travel stays steady while vibration runs.
Climbs embankments and works uneven terrain where a mechanical-drive roller of the same weight would need a winch.
