Double drum rollers and other construction machinery is capital dense, technology-intensive, and related industrial relations are very strong products, a wide range of technology, business, the host plant's products to enhance the technological content, double drum rollers need a number of supporting enterprises to work closely with about 60% ~ 70% of the ancillary products need to be provided by the plant. Road roller host production to the overall product design, structural components manufacturing, product parts purchase and assembly as the main content.

What are the operating regulations of double drum road roller?

1、When working, the drum should be started first before vibration, and the internal combustion engine should reach medium speed first, and then adjust the high speed.

2、Variable speed and exchange should be stopped first, and the speed of the internal combustion engine should be reduced when changing speed.

3、It is strictly prohibited to vibrate the roller on the hard floor.

4, trample the soft roadbed, to first not vibrate, trample 1~2 times, and then vibrate.

5, rolling, vibration frequency should be consistent. If you can adjust the vibratory roller, adjust the vibration frequency first, and then only work, can not adjust the vibration frequency without vibration.

6、Adjustment of reversing clutch, impact clutch and brake should be done after the main clutch is disengaged.

7、It is not allowed to use quick file when going up and down. When turning sharply, it is forbidden to use fast gears when rolling on small rotors including articulated vibratory rollers.

8、The vibration cannot be engaged when the roller is traveling at high speed.

9, when stopping, first stop vibration, then put the mechanism in the middle position, the transmission is placed in the blank space, pull the handbrake lever, the internal combustion engine idling start a few minutes to turn off the engine.

10, other work requirements in line with the provisions of the static pressure roller.

Whether uphill or downhill, the layer under the asphalt mixture should be clean and dry, spray asphalt binding layer, so as to prevent the mixture from slipping when pressed.

For both uphill and downhill rollers, the drive wheels of the rollers should be at the back. This has the following advantages: uphill, the driving wheel at the rear can withstand the driving force provided by the ramp and the machine itself, and the front wheel initially compresses the road to withstand the larger shear force generated by the driving wheel. Downhill the impact force generated by the self-weight of the rollers is counteracted by the braking of the drive wheels, and only the mixed material pressed against the front wheels has the ability to support the shear force generated by the rear drive wheels.

When rolling uphill, the roller should start, stop, and accelerate in a steady manner, not at too high or too low a speed.

Prior to uphill rolling, cool the mixture to the specified low limit temperature and then perform static pre-compression, using vibratory compression, until the mixture temperature drops to the lower limit (120).

Downhill rollers should avoid sudden speed changes and braking.

When performing downhill rollers on very steep slopes, first pre-compress with a light roller and then compress with a heavy roller or vibratory roller.
