| There are 2 diagrams illustrating elevator
conveyor systems. |
| |
| Diagram 1: shows a very common construction.
The drive wheel is at the top of the elevator system. The first
support after the drive wheel ensures the best possible engagement. |
| |
| The second support should be located in
such a position that the weight of the belt "sag" between the
first and the second support is sufficient to maintain the correct
belt tension. This ensures continuous positive engagement from the
sprockets on the drive wheel. If there is insufficient distance between
the first two supports, the tensioning belt "sag" should be moved to
the area between the second and the third support. When provision has
been made for adequate tensioning by following the above points, the
belt can then be enclosed and allowed to run inside the conveyor
framework for the remainder of the return leg. |
| |
| At the point where the belt runs negatively,
between the horizontal and incline (E-radius), it can be held
in position and retained at the sides by the synthetic guide rails.
Another option is the use of the hold-down
segment built into the underside of the belt. These segments attach
onto a suitable rail incorporated in the conveyor support bed. |

|
| |
| |
| Diagram 2: shows a similar elevator
system. It is constructed in the same way. In some exceptional
cases, more tightening/tensioning may be necessary. This
can be achieved by using weights or springs. |
