XD122E Double Drum Vibratory Road Roller
Spacious and bright cab features wide visibility and comfortability, and the suspensible seat, speaker and safety belt are equipped in the cab.
XCMG unique cylinder structure features strong rigidity and strength, and it adopts the special bearing, high limit speed and strong carrying capacity to avoid the polarization of the vibrating drum.
The lubrication method of the vibration bearing is simple and convenient, and the fault of the lubrication system is low.
The control panel could be adjusted in 180 degrees, and the operator could easily operate the machine during Forward and Reverse, and each compaction mode has good visibility.
It adopts hydraulic drive and electric-hydraulic control technology, contributing to simple operation.
Automatic watering and vibrating system improves the flatness of the road compaction.
XCMG patented crab mechanism and dual-articulated steering could ensure staggering distance of 200mm between the front and rear drums, which is convenient for the side compaction and turning compaction. When the dual-articulation is activated simultaneously, the min. turning radius could be 6000mm.
Adjustable resin mud-scraper features easy operation.
Leading in industry of compaction and watering function
The vibration frequency is adjustable in certain range, two gears of amplitude adapt to the asphalt compaction of different depth.
The unique separate vibration function. The front and rear drums could vibrate at the same time, and the drum could vibrate separately, improving the compaction efficiency.
The key imported parts: imported hydraulic plunger piston and motor feature higher centrifugal force and theoretical gradeability. The watering pump and vibration bearing are all of imported parts. There are multiple configurations for the engine to choose to meet various conditions.
Large capacity plastic water tank, three-stage filtering, and double watering systems and interval 7-gear watering ensure the smooth watering.
The engine hood could be opened from three sides, and the engine and hydraulic pump and each control valve could be checked easily.
