Track tightness cannot be adjusted randomly! This standard should be kept in mind! Excavator Track Link Made in China
The tightness of the excavator track is just like the size of the shoes worn by people. It must be adjusted to the best state to move forward. Excavators often change the tightness of the track during walking, and the tightness of the track also determines the wear degree of the chain to its contact parts.Excavator Track Link Made in China
Therefore, adjusting the tightness of the excavator track is a compulsory course for everyone.
Importance of track tightness
We all know that the "four wheel belt" on the lower frame includes tensioning wheel, roller, carrier roller, drive wheel and track. Some excavators always replace the carrier roller and roller, while others can be used for a long time, which is closely related to the tightness of the track. Therefore, it is the correct method to flexibly adjust the tightness of the track under different working conditions. Let's introduce it in detail.
Adjustment principle of track
▊ The first point: when the excavator is working on a hard ground, it is necessary to adjust the track a little tighter, so as to avoid the track loose and too long, collision with the lower frame, causing wear.
▊ Second point: when the excavator is working on the soft ground, it is better to adjust the track loosely, because the working condition is easy to attach soil on the joint and track, which can reduce the abnormal pressure generated by the soil on the joint.
▊ Third point: When adjusting the tightness of the track, do not adjust it too loose or too tight. It must be moderate. If the track is too tight, it will affect the walking speed and driving power, and will increase the wear between various parts. If the adjustment is too loose, the loose track will cause great wear on the drive wheel and drag chain wheel
▊ Note: one point will be ignored by many people. When the loose track sags too much, it is very likely to contact with the frame and wear the frame. Therefore, it is necessary to master an accurate degree during adjustment, otherwise the failure will surely follow!
Track tension standard
Rotate the excavator to one side and lift the unilateral track off the ground. Generally, the maximum distance between the lower frame and the chain is about 320mm-340mm.Excavator Track Link Made in China
