Hydrostatic roller:Mechanically own gravity, for a variety of compaction, dense the laminated layer by permanent deformation. Divided into steel wheel and tire types.
Steel Wheel Roller:Runner wheel construction divided into light grind, slot grind and groove sheep-foot grind. Light grind the most common, mainly for pavement compaction. Driven by mechanical or hydraulic, It can concentrate on the protruding portion, high compaction flatness, suitable for the compaction of asphalt pavement.
According to the shaft arrangement there is single shaft single wheel, double shafts double wheel, three shafts three wheels, etc. With internal combustion and engine as power,driven by mechanical or hydraulic. Usually the front wheel steering, with good mobility, rear-wheel drive.
In order to improve the steering and rolling performance, we should adopt the structure articulated steering and all-wheel drive. Hinged front frame and chassis to reduce body swing by unsmooth pavement. Hydraulic control, hydraulic steering cylinder control. Drums are equipped with front and rear scraper to remove the adhesive substance on Drums. When the sprinkler system is also equipped for the compaction of asphalt pavement on DRUM Sprinklers to prevent the adhesion of asphalt mixture. The force can be increased to fitted iron, sand, water, etc. in the DRUM increase weights.
The main technical parameters of steel wheel roller is the machine weight and line pressure. Machine's weight range of steel wheel roller at 80’s is about: the two wheel roller： 2 to 13 tons, three wheel roller: 1 to 15 tons, according to need it can be pressurized heavy 1 to 3 tons, triaxial three wheel: 13 to 14 tons , after added weight pressure is 18 to 19 tons.

Safety operation rules for road milling machines
Inspection work before start to work 
1、Check the oil level of tank.
2、 Check oil position of milling machine’s engine. Change the engine oil after the first 250 hours trial operation, changing every 500 hours.
3、Check the coolant level
 4、Check the cooler of milling if is clean or leakage.
5、Check hydraulic oil level, to prevent leakage.
6、Check the chain tension of device drive ,to match the specific application adapt to road conditions.
7、Check the working condition of milling machine’s head and the knife holder. 
8、 Check collecting belt and discharge belt tension also its deviation.
9、 Check if it fixed the discharge belt rope and shackle , replace it if there is any damaged, otherwise it happened to personal safety and machine itself.
OPRATION
1、Make sure that no one in the car or under the car, and no one is nearby dangerous area before start the milling at any time.
2、Make sure all guards and covers in the correct position and securely fastened.
3、 Remove all obstacles from road work zone, on a non-whole road, drive carefully, avoid landslides, overturning.
