ome buyers like dealers and Distributors may not professional in excavator buckets. They must have such questions like “how to check the excavator bucket quality?”, “what is the most important for the excavator buckets?”, “Are these attachments in stock ok?”.
Here is a guide to show you the most important issue: dimensions, even mounting dimensions. We know the buckets will be fit with excavator arm and bucket link.
So first of all is mounting dimension:
- Dipper gap, it should not less than the width of excavator dipper. Best is 1 or 2mm larger.
- Bucket link gap, it should not less than the width of bucket link. Best is 1 or 2mm larger.
- Pin centre. Normal tolerance is +/- 0.5mm.
- Dipper pin diameter.
- Bucket link pin diameter.
- Bucket boss width.
The pin hole will be control severely, normal tolerance is +0.3/+0.2mm. Otherwise, big gap between pin and pin hole will create noise and shakes. Nobody want to see that, right?
Next is the overall height and width. They are also important because of the capacity. If you buy a excavator bucket with correct pivot dimensions but wrong shell, it will still be a problem. Big shell causes high-weight that mini excavator could not stand; incorrect shell is not efficient with a large emission machine.
