Track Link For SK200-8

Production introduction

Track assy:            

Classification: There are two types: holistic and combined.            

The integral track is the meshing teeth of the track board, which tends to mesh with the driving wheel. The track board itself becomes the rolling track of the wheels such as the supporting wheel.            

Features: Easy to manufacture, but fast wear and tear.            

The multi-purpose combined excavator features small pitch, good rotation and fast walking speed. Long service life.            

Most of the materials used are light weight, high strength, simple structure and cheap rolling plate. There are single tendon, double tendon, three tendons and so on.            

Three tendons are commonly used in excavators. The characteristics are: the height of the rib is small, and the strength of the Caterpillar board is large. Smooth movement, low noise.            

There are generally four connecting holes on the track board, and two mud clearing holes in the middle, which are used to automatically remove clay. There are overlapping parts between two similar crawler boards to prevent damage caused by stones clamped in the middle.            

The excavator on wetland can use triangular track board, whose cross section is triangular, which can compact the soft ground and improve the supporting capacity.

Sizes

Our track link assy is applicable to below models:

Characterristics

1. Hign-degree harden treatment ensure the most strength and wearness.

2. The track pin is done the tempering and the surface intermediate frequency quenching treatment,

which ensure the sufficient hardness of core and abrasion resistance of external surfaces.

3. The track bushing is done the tempering ensure the reasonale hardness of core and abrasion

resistance of internal and external surfaces.

Quality control procesures

When material come inside our factory, we need to analyze the material compostion. after several parts are heat treated, we need to check the hardness before all are done.And our inspectors will check the sizes at ramdom when parts are being machined or assembled

Particle Examination: Magneric Particle Test of Each Track Link to Eliminate Detective Product　

And we will check the size of every track bush hole of every link piece.

FAQ

1. How can you control your quality?

When material come inside our factory, we need to analyze the material cost. And when front idlers and sprocket rims material are casted. We need to analyze the composition to see if the material is qualified or not. When track rollers, carrier rollers and front idlers are being assembled, we need to oil leakage testing. After several parts are heat treated, we need to check the hardness before all are done.And our inspectors will check the sizes at ramdom when parts are being machined or assembled. All of these can guarantee the parts with correct sizes and good quality.

2. What is the percent of your parts for overseas market?

70percent of our parts are for overseas market.

3. Is there any guarantee of your parts?

There are 6 months guarantee time for excacavar parts under normal working conditions and 3months guaranteet tiem for bulldozer parts under normal working conditions.

4. How do you offer guarantee?

If parts are broken due to manufacturing problem, we will deduct the value for next order amount or offer you brand new one to replce.
