How long of an elevator bolt do I need? |
|
| |
When installing buckets on an elevator belt, use this simple formula: |
|
| |
(belt thickness + bucket back thickness + washer thickness + nut thickness + 1/4 inch) |
|
| |
|
|
| |
What is a "digger" bucket? |
|
| |
Some materials can form a hardened crust along the side wall of the elevator boot, and powders sitting over time |
|
| |
can become rock hard. Both of these issues can cause premature elevator bucket wear. Digger buckets are |
|
| |
designed to have slightly more width and projection than standard buckets, thereby "digging" through or breaking |
|
| |
apart the hardened material, helping to prevent added wear to the standard buckets. Digger buckets are |
|
| |
traditionally made from steel, however nylon buckets may also be used depending on the application. |
|
| |
|
|
| |
How many digger buckets do I need? |
|
| |
For most applications, use one digger bucket for every nine standard buckets. |

Can I use buckets on an overlap splice? |
|
| |
An overlap splice doubles the thickness of the belt, so a bucket's projection will increase on the overlap. |
|
| |
Usually this will not cause a problem, but if it does, you can use buckets with one inch less projection or cut |
|
| |
the tip of each bucket by half an inch on the spliced area. |
|
| |
|
|
| |
When using an overlap splice, how much extra belt should I use for the splice? |
|
| |
The length of the splice should be three times the width of the belt. |

How often should I replace head pulley lagging? |
|
| |
Lagging should be replaced every time the elevator belt is replaced. |
