Walk behind roller, also known as the name, walk behind roller compactor, is a kind of mini road roller that needs two hands to hold the handle for compaction. It is lightweight and very easy to operate, which makes it suitable for the compaction of narrow areas, and some places that large road roller can’t enter for compaction. In addition, its price is much cheaper than ride on road roller for sale. That’s why it’s so popular. The walk behind roller for sale are walk behind vibratory roller in our factory, which includes two types, single drum walk behind roller and double drum walk behind roller. Check the technical parameters of the two types below and select the model you want now. We will reply to you as soon as we receive your inquiry.

Walk Behind Vibratory Roller
The static road roller and vibratory road roller are the two different types of road roller equipment. The static smooth wheeled rollers are mainly used to make the surface smooth and the vibrating road roller is mainly used to ensure the degree of compaction. In addition, they also work in different ways. The static road roller compact the pavement by their own gravity, while walk behind vibratory roller strengthen the compaction by vibration. They can both used for road compaction. But the vibratory road roller is widely used, the compaction effect is better and the speed is fast, though the static model is much cheaper. If you are planning to purchase a cost-effective small road roller for sale, I suggest you buy the walk behind vibratory roller for sale in Yugong Machinery. We have both gasoline and diesel engines, you can choose according to your own requirements.
The Working Principle of Walk Behind Vibratory Roller
The source of the vibration generated by the vibratory roller is the hydraulic motor. Its oil path generates a magnetic force through a control coil in the solenoid valve, and drives the spool of the control valve to move, thereby connecting the motor to the oil pump or the return line. The hydraulic motor keeps moving under the action of hydraulic oil and drives the vibrator to excite vibration. The exciting force makes the compaction density of the machine stronger, which makes the compacted road surface difficult to be damaged and can be maintained for a long time.
The Reasons Why The Road Roller Steel Wheel Doesn’t Vibrate:
1.Control circuit fault. The power circuit of the control valve is in the state of disconnection or the control coil is damaged, which will cause the valve core can’t be commutated and can’t be connected with the hydraulic oil chamber and drive the motor to generate excitation.
2.Reversing valve malfunction. When the hydraulic oil is polluted, the impurities enter the closed position of the slide valve and cause the solenoid valve can’t drive, which will cause the hydraulic motor can’t be connected to the oil circuit, resulting in the roller can’t produce vibration.
How to Deal with The Failure of steel wheel without vibration?
First, check the circuit. Use a wire to connect one end of the circuit to the power supply and the other end to the live wire end of the drive coil of the solenoid valve. If the solenoid valve can vibrate, it indicates that the power circuit fault. Then please check the circuit and process it. If there is still no vibration after connection, please remove the solenoid valve and push the valve core manually. If the vibrating wheel vibrates, it indicates that the electromagnetic control coil is damaged. You can also use the wire and the solenoid valve’s terminal to scrape the fire. If there is no spark, the solenoid is disconnected. If there is spark, it means that the electromagnetic coil work normally. But it still can’t vibrate, which means the slide valve is stuck and please check the valve.
