CP221 and 271 are heavy pneumatic rollers designed for the surface sealing and compacting of

asphalt together with steel-drum rollers. Due to their very high weight these pneumatic rollers are

also suitable for the compacting of subbases and base courses.

CP221 has three steered wheels at the front and four drive wheels

at the rear, mounted on a rigid axle.

CP271 has five wheels at the front and four at the rear, mounted on a rigid axle.
