The HG220 handles comprehensive road construction operations including highway construction and maintenance, municipal road grading, airport runway preparation, parking lot development, and large-scale earthmoving projects throughout Southern Africa. The versatile blade control system enables maximum 450 mm lift above ground and 535 mm maximum cutting depth, whilst circle center shift extends 525 mm right and 530 mm left. Moldboard side shift reaches 965 mm both right and left, providing 2,367 mm maximum shoulder reach outside rear tire (right) and 2,372 mm (left) with frame straight, accommodating wide road construction requirements.
The 1,410 mm diameter circle with hydraulic rotation control enables 360-degree blade positioning, whilst maximum blade angle reaches 90 degrees right or left with 29 to 77 degree blade tip angle adjustment. This comprehensive range facilitates precision grading across varied applications from highway shoulders to drainage ditches throughout regional infrastructure projects.
The hydraulic power steering system provides stopped engine steering meeting ISO 5010 standards, delivering 7,300 mm minimum turning radius with 49-degree maximum steering range right or left. The articulated frame achieves ±26-degree articulation for enhanced maneuverability across construction sites. The solid bar construction welded steel sections front axle maintains 640 mm ground clearance at pivot with ±17-degree wheel lean angle and 32-degree total oscillation, ensuring stable operation across uneven terrain conditions.
The oscillating welded box section tandem drive measures 614 mm by 225 mm with 22 mm inner and outer sidewall thickness, providing robust construction. The 1,535.4 mm wheel axle spacing combined with ±13-degree tandem oscillation maintains consistent ground contact across irregular surfaces, critical for achieving precise grade specifications throughout Southern African road projects.
Motor graders are specialized road construction machines designed for fine grading, leveling, and finishing operations across road building, maintenance, and earthmoving applications requiring precise surface control. The Hyundai HG220 delivers 160 kW (215 HP) from its Cummins 6CTA8.3 turbocharged aftercooled engine, managing a 4,320 mm moldboard for highway construction, municipal road maintenance, and large-scale infrastructure development. We supply the HG220 to Southern African contractors with comprehensive technical support and genuine parts availability through our established regional dealer network.
This 15,800 kg motor grader excels in demanding road construction and maintenance operations requiring exceptional precision and productivity throughout the region.
The Cummins 6CTA8.3 powerplant comprises six cylinders with 114 mm bore and 135 mm stroke, displacing 8.3 litres. The turbocharged aftercooled engine with dry-type air cleaner operates from a 370-litre fuel tank, supporting extended operational periods between refueling essential for remote Southern African construction locations.
The standard 15,800 kg operating weight (including lubricants, coolant, full fuel tank) distributes 11,060 kg on rear wheels and 4,740 kg on front wheels across wide 17.5-25 12PR L3 tyres as standard specification. The 2,120 mm tire centerline width and 2,565 mm outside tire width provide a stable platform for precision grading operations.
The dual pump and dual multi-way valve hydraulic system with priority braking and steering delivers 99 litres per minute output at rated engine rpm operating at 17.5 MPa maximum system pressure. Hydraulic locks on scraper lifting, front wheel tilting, traction frame tilting, power tilting, frame articulation, and other circuits ensure positive control. The foot-operated, hydraulically actuated service brakes operate on four tandem wheels with 3,613 cm² total braking surface, whilst flexible shaft control drum parking brake provides secure machine positioning.
Optional attachments expand machine versatility, including automatic leveling device providing precise 2D control system with height and slope control, rear ripper with three-tooth standard or five-tooth optional configuration achieving 436 mm maximum ripping depth, mid-mount V-type scarifier with 11 shanks achieving 210 mm maximum scarifying depth, and front dozer blade for material spreading applications.
