Used XCMG Roller XS123J 

Fuel consumption is 6–8 L/h for standard stabilized soil base operations—low for this tonnage class—offering a clear cost advantage for long-term contracts. Adjustable power modes allow for fuel savings during light loads and maximum power for heavy-duty tasks.
Emissions compliance
The new model meets National IV standards, ensuring unrestricted access to construction sites and municipal projects across China.
II. Compaction Performance: Dual-frequency and dual-amplitude capabilities suit most operating conditions (Key Highlight)
12-ton operating weight with freely switchable dual-frequency and dual-amplitude settings:
Low frequency/high amplitude (240 kN centrifugal force): Ideal for subgrades, crushed stone backfill, and deep compaction of thick stabilized soil layers; ensures deep penetration and rapid achievement of density targets.
High frequency/low amplitude (160 kN centrifugal force): Ideal for asphalt surface layers, thin-layer patching, and surface finishing; ensures a smooth finish without material displacement or aggregate crushing.
Unique “three-centers-in-one” vibration technology ensures uniform force distribution across the drum and consistent compaction, preventing issues where one side is dense while the other remains loose.
Drum features a four-point cylindrical support structure with an official service life of 10,000 hours; highly resistant to oil leaks, weld failures, and deformation—far outperforming generic models in the same class.
