At present, the use of roller is more and more. With the vigorous development of infrastructure construction, road construction in many places requires the use of roller, technical transformation, and roller maintenance. How to improve the road environment in China and the use of roller parts are also increasing. In order to better adapt to the modern working mode, we should have better technology for roller Technological transformation, only in this way can we make our production more smooth, so how should we proceed?

　　1. The belt of the roller steering hydraulic pump is easy to wear, which makes the engine turn heavily at low speed. Some rollers use the semi-hydraulic steering of the joystick type, and its control technology is not easy to master.

　　2. The transmission belt or rubber ring is used to connect the engine and gearbox of some rollers. It is difficult to assemble and disassemble the roller parts, and the parts are easy to be damaged.

　　3. We should also fully understand our roller products, fully understand what kind of product transformation should be used for different roller products, so as to prevent them from being unable to be used after transformation.

　　4. We should fully understand the vulnerable reduction of the roller. The reverse clutch of the roller gearbox is a friction plate, which has complex structure and is easy to slip and damage parts.

　　For the use of roller accessories, we should carry out reasonable transformation to prevent unreasonable conditions affecting the use of our equipment. After the formal transformation, our equipment will be well improved.

　　Mastering the technology of the press makes the maintenance much easier.
