Shantui SR22H-G Single-Drum Roller

Extra-wide pressurized cab with roof-vent air conditioning and fresh-air exchange. Premium interior trim, a pillar-less front section for a clear view of the drum, and large storage compartments.

The sealed cab keeps ear-level noise below 80 dB. Steering lock-to-lock is about 7 turns with steering effort under 20 N. The three-stage isolation mount supports continuous 600-minute shifts, and the joystick integrates direction reversal, amplitude selection and vibration on/off. Six LED work lights and an 8-inch color display are standard.

The shockless vibratory drum starts and stops smoothly. Balanced weight distribution gives even mat finishes, with compaction density on par with industry benchmarks.

Front and rear tow hooks; cup holder in the right console; reversing camera standard; a water-level sight window simplifies daily checks.

Filter elements are grouped and reached by opening the hood. The inverted engine layout leaves room around service points, the front water tank has a removable dust screen, and the oil sump and coolant drains are routed outside for shorter servicing.

Active obstacle-avoidance system, compaction measurement, 360-degree cameras, padfoot drum and electric hood opener are available on request.

Powertrain control with auto-idle and ECO mode cuts combined fuel use by about 20%. Service intervals are 500 h for the engine and 1,000 h for the drive axle and vibratory drum.

A Linde electro-hydraulic system closes the loop on vibration frequency, with four frequency ranges for different soils. Real-time speed readout and constant-speed control hold the target pace; vibration starts or stops by one key or automatically, and three-stage throttle control keeps engine speed steady in the adjustable second stage.
