Q:How about roller Qingdao kotai heavy industry.

Good, the price advantage, and other brands also have a function, but as long as it is mechanical or any other products, there are some deficiencies, it can not be perfect. If you want to use it or choose Qingdao Ketai, there are certain advantages at least economic cost

Q:How do the rollers see dual vibration, single vibration, double drive, single drive, double steel single steel?

Double steel is a finger press. It has two front and rear steel wheels. The single steel refers to the front of the steel wheel, and the back is the rubber wheel. Steel wheels are mainly pressure bed, and some are asphalt. Some are front and rear rubber wheels, which can only be used to press asphalt.Double drive means that the front and rear steel wheels (or rubber wheels) are provided with drive motors on the side, so that the front and rear two motors drive the wheels to roll.

Q:How often does the roller change the engine oil? Is there a master pointing at one or two?

To see what brand of your engine, diesel, Hangzhou, Yuchai and so on domestic engine in general. From the beginning of the first factory replacement engine is the timer display 300 hours or work for three months should be replaced, at the same time to replace the filter, replacement according to the service condition and working environment and then, usually 250-550 hours. The worse the environment, the shorter the time, but less than 250 hours, as long as the oil viscosity, and through the oil traces can see the oil dipstick, metal color (oil slightly transparent), we do not recommend replacement, because it is a waste. Replace the oil and replace the filter at the same time, otherwise it will be wasted. In fact, when we go to the site service, listen to the user said, as long as life is not too busy, usually only once a year.

Q:The asphalt pavement here is divided into three layers, the two layer with rubber tire roller for rolling, the surface layer is needed for the rubber roller, wherein the two layer is below AC, the top layer is SMA series.

The asphalt aggregate ratio and slag amount is more than 6% SMA can not use leather wheel, this is the result of the test section, the rub mastic floating that the depth of the surface structure reduces in this case leather wheel, skid resistance is reduced, skin wheel function is rubbing that is dense, so more suitable for dense graded mixture.

Q:What is the action of a vibrating gas? What is the principle of action and what is the working principle?.

Vibratory roller is to use its own gravity and vibration compaction of various construction and road construction materials. In highway construction, vibratory roller is suitable for compaction of various non cohesive soil, crushed stone, crushed stone mixture and various asphalt concrete, and is widely used.Static pressure: 1 tons roller weight 1 tons, static pressure strength is 1 tonsVibration: 1 tons roller, vibration force 2.5 tons, vibration pressure strength 1+2.5=3.5 tons.The working principle of vibratory roller1, the emergence of vibration - mass eccentric + rotationIn the picture, the big circle is a vibrating wheel, and the blue green is an eccentric vibrator. When running at high speed, the eccentric steel force drives the big steel wheel to vibrate together, and generates exciting force.

Q:How many rollers are there in the roller?

Single wheel mechanical rear wheel drive.The single steel wheel is fully hydraulic and can drive both front and rear.Full hydraulic pre vibration of double steel wheel.Tire type roller mill, single or full shaft.

Q:XCMG vibration roller 14J and 14JC what is the difference?

As for where there is a difference, you call Xugong after consultation. Not used, basically unclear, or go to their official website to find out, see if there is any?. Hope to help you.

Q:What's the use of this roller? What is the difference between a roller and an ordinary roller?

This is a convex block roller, is adding a layer with a convex block device mounted on the original circular surface of the base, consisting of two semicircle. This roller is mainly used for the compactness of roadbed. In general the main base material is not easy to be smooth when compacting it will be used

Q:Building construction, taking vibratory compactor as an example, illustrates the method of compaction Matters to be attended to?

Roller static pressure 2 times. The overlap wheel width is 1/3 to 1/4, and the rolling speed is 25 to 30m / min. Then crush it 6~8 times with shock. Overlapping rear wheel 1/2, rolling speed 30 ~ 50M / min.

Q:When the new high-speed road roller is used to press the road surface, it will cause cracks in the surrounding houses. What are the criteria for compensation? How many meters away from the subgrade is the range of compensation?

In this case, the local government can be reflected in the situation, and for the corresponding losses caused by residents, or compensation.
