Knowledge sharing: Crawler board is one of the chassis parts of construction machinery, and it is a vulnerable part of the construction machinery used. Imported rubber material is used. The rubber used on the rubber board is oil-resistant, asphalt-resistant, corrosion-resistant, diesel oil-resistant and wear-resistant. There will never be cracks in the rubber board. The rubber on the ground is 12-13MM higher than the metal surface, and the track composed of trackpads will not destroy the road surface when driving on the highway.

Question: Reasons for derailment of paver track and solutions?

Answer: Analysis of the causes of the failure may be due to the tension cylinder not fully ejected, or abnormal wear and tear of the guide cam flange.

Track tension of paver is not very suitable in the initial use. When turning radius is small, the right track derailment occurred, but the tensioning cylinder was not adjusted in time. After the paver has been in use for a long time, the cylinder always stops in one position. It is very difficult to tighten and relax (when the paver is repaired, the tightened cylinder is retracted by jack), which makes it possible for the driver to install the crawler forcibly. In this process, the inclined track will pull the installation side plate of the guide wheel outward, making it inclined outward, which is more likely to cause derailment of the track. Appropriate adjustment of the tensioning cylinder can reduce derailment of the track, and after derailment of the track, we must try to retract the tensioning cylinder to the innermost side and install the track again.

Question: How should the Caterpillar board avoid wear and tear?

Answer: Pollution will greatly increase wear: friction materials (such as sand) will produce friction between all contact surfaces, and significantly reduce the service life of trackboard unit components. In a word, regular cleaning and maintenance are very important to improve the service life of components.

Question: What are the requirements for the use of trackpad rubber?

Answer: When paver works, the adhesion force is realized by friction between rubber on track board and ground. When turning, it is realized by the difference of walking speed between two sides of track. During turning, there is a great friction force between track board and ground when lateral displacement occurs. If the strength or deformation ability of rubber is not enough, the track board will be seriously damaged, such as wear and tear. Tear and so on. When hot mix asphalt mixture is paved in summer, the increase of ambient temperature leads to the decrease of rubber deformation ability, and the damage situation is more serious at this time.
