Lead to a common cause of severe wear: the accumulation of dust and tar residue (incomplete) clean machine transitions too fast when walking backward chain tension is too small sliding or rotating parts there is friction materials (sand, dust, etc.)
How to avoid wear and tear: pollution can largely increase the wear: friction materials (such as sand, etc.) in all friction between contact surfaces, and significantly reduce the service life of the crawler unit components.In short, to improve the service life of the components, regular cleaning and maintenance is very important.
Improve the service life of the method: daily thoroughly clean the machine regularly check parts, in order to take effective measures in time against a worn or damaged components
Wear segments change: polyurethane segments or rubber crawler plate reaches wear limit must be replaced, which must be before is shown in the bottom steel tooth replacement segments.
Steel plate on the asphalt friction (traction) than polyurethane (pu) or rubber is much more serious.This will directly affect the speed, will affect the work efficiency of the machine.
At the same time, pu or rubber panel can minimize the road damage, so as to avoid may therefore lead to compensation.In general, if the original is in good condition of the road or damaged after being worn crawler plate rolling on the ground, then you must repair or reconstruction of the road.If in polyurethane crawler board to be able to see the left and right sides of the plate, then do not necessarily need to replace segments.
Segments service life calculation formula through the formula to calculate the wear degree, help to arrange the maintenance time, increase the availability of the machine.For as accurately as possible estimate crawler unit the service life of wearing parts, you should use the following formula:
Crawler plate wear calculation example (W1)
EPS segments after working 750 hours of wear is about 40%, measure the height of 43.2 mm.Through these data to calculate the service life of wearing parts under the condition of normal wear.Calculated until the EPS crawler board replacement, the service life of wearing parts is 1875 hours.* % according to in the table behind the wear state.
* * use commonly 100%, for more than the value, will aggravate the damage of other components.
Please note: this formula helps to estimate degree of wear track components, but only a statistics.The change of some factors, such as pollution degree, damage degree (such as result in component fracture crack or
Cracks, etc.) or maintenance cycle will make the change.
The percentage of the degree of wear and tear is measured at a specific time, may/will change in the future, so the calculation and the service life may be shortened or extended.
