LTD220H road roller  is equipped with Cummins turbocharged diesel engine, which has a large power storage. It adopts the hydraulic all-wheel traction transmission mode and has a variable-frequency variable-amplitude rapping device, SAUER/REXROTH planetary reducer, and built-in wet multi-plate brakes. When fuel is off, braking is automatically applied, so it is safe and reliable. It has a high-strength fully closed driver’s cabin. Besides, there is an optional digital display-type compactness detector so as to guarantee the quality of compacting.
