BMW SA145 paver
The Caterpillar board is more common in the engineering machinery and equipment, among which the paver's crawler board is one of them. The requirements for the Caterpillar board are long service life, wear-resisting, corrosion resistance, and good matching with the whole machine.

So what kind of pavement can the crawler board apply to? It is generally appropriate to walk on a very soft ground (wetland).
1. The rough ground of a large obstacle, such as a rolling stone and a fallen wood, can not be used.
2. When the obstacles are unavoidable, it is necessary to slow down at half speed.
3, the selected track width, starting in the floating body, range of ground pressure is no problem, try to use the track plate narrow, trackboard wide used, the split crawler board, the crawler board load becomes large, complex rubber crawler board will be tracked, plate bending, caterpillar joint fracture wreck, pin, pin causes drop or track bolt looseness

So we usually have to walk on the pavement suitable for paver so that the paver can walk on its own. If the dirt on the track plate is attached, we must clear up in time, protect the track boards, and paver in order to go further and further. (home of engineering machinery: http://www.700618.com/)

The following is to share a knowledge about the low leveling of the paver.
Two Liugong pavers appear to have low smoothness during operation. At the beginning of each paving, the phenomenon of ironing is easy to occur, and the ironing board always jumps and jumps when paving.
Terms of settlement：
Inspection found that the left and right spiral feeder of the machine was artificially adjusted, and the respective positive and reverse proportional solenoid valves were also exchanged, that is, the spiral forward feeding mode was adopted.
In the way of paving, in the initial stage of material level is in high position, resulting in elevation of the screed and the spiral feeder reversal exerts an upward force to the ironing board, not only caused the screed is always jumping, also make the floating screed of paver thickness increased, stand the smoothness is reduced.
In addition, in the way of spreading, the spiral feeder in the running process, because the front hopper volume is larger, the larger particles will be rolled in front, and then spreading at the bottom, fine material is always at the top. Although it looks no segregation, and good finish, but if the core will find the density of the core, the upper part is better, and the lower half part of the compactness of the poor, and cavitation.
As a result, the contact area between the ply and the joint decreases, resulting in the decrease of the binding force and the poor permeability. It directly affects the life of the pavement. The screw feeder of the machine is replaced, and the electromagnetic proportional valve is exchanged, so that all the paving works are normal.
