Komatsu Track Shoe Ass'y 17M-32-01340 For D275

A: There are many types of track shoes for Komatsu D275 crawler assembly. Common ones include single-tooth track shoes, which are characterized by a small number of grousers and a relatively simple structure. They are suitable for working environments such as relatively soft soil or sand, can provide good adhesion, and have less resistance when driving on such ground, which is conducive to improving the working efficiency of the bulldozer; double-tooth track shoes increase the number of grousers, while ensuring a certain adhesion, the grip on the ground is stronger, suitable for more complex working conditions such as general construction sites, and can cope with ground of different hardness and terrain; there are also three-tooth track shoes, which have denser grousers, stronger grip and stability, suitable for working in rugged, muddy or steep sites, can effectively prevent equipment from slipping, and ensure the smooth operation of bulldozers in complex terrain. In addition, track shoes can also be subdivided according to the presence or absence of mud holes, width, etc., and different types meet diverse engineering needs.

A: The working environment is an important influencing factor. When working in harsh environments with many rocks and high-hardness materials such as mines and quarries, the tracks frequently rub and collide with sharp objects, and the service life will be greatly shortened. In contrast, when working in relatively soft and flat sites, the track wear rate will be much slower. The frequency of use of the equipment also has an impact. Long-term, high-intensity continuous operation causes the various components of the track assembly to continuously bear loads, which accelerates fatigue wear and reduces the service life. Daily maintenance is also critical. Regular cleaning and lubrication of the tracks and timely adjustment of the tension can effectively reduce component wear and extend the service life. On the contrary, if maintenance is neglected, the tracks are prone to failure and their lifespan will be greatly reduced. In addition, the operator's driving habits should not be ignored. Improper operations such as sudden acceleration, sudden braking, and frequent steering will cause the tracks to bear additional impact and aggravate wear.

A: Common faults include track chain wear, which is caused by long-term operation under complex working conditions, frequent friction between the chain links and the ground, drive wheels, etc., which will affect the transmission accuracy and strength of the track when worn severely; track pins are loose or broken. The impact force and vibration during operation may cause the track pins to gradually loosen. If not handled in time, they are prone to breakage under continuous force, causing serious faults such as track derailment; in addition, uneven wear of track shoes is also common. For example, when operating on rugged terrain or when the center of gravity of the equipment is unreasonable, some track shoes will be under greater pressure, resulting in local excessive wear, affecting the driving stability and passability of the entire machine.
