GW207G is mostly worked in with the spreaded asphalt machine. Because of the very width vibrated wheel(1.7m) and the fine pressing speed which bring the great working ability. It is mostly worked with the largest spreaded asphalt. The roller is applied to builded-road, parking area and industry area, it is especially suited for express shoulder, side walk and the limited area.
Main features:
Main features:
1) Hydraulic vibration, great centrifugal force and high compactness.
2) Machnical travel, pneumatic tyre drive, three speed changes both forward and backward and high speed travelling.
3) Articulated frame, hydraulc steering, small turning radius and fexible drive.
4) Full anti-corrosice spray water system, large capacity water tank, electrical pressurized sprinkler and unique nozzle design which covered all of the steel and pneumatic wheel.
5) Two sets of brake devices, a hand crake and foot pedal brake, assure the machine's safety and dependability.
6) Both clutch and foot pedal brake system are sdopted hydraulic power and saving manpower to operate.
