Venting System |
 |
Every Cable Arm clamshell is equipped with a passive venting
system. This venting system serves 3 purposes:
|
 |
 |
Open While Lowering
While the bucket is being lowered, the vents open
- allowing water to flow through. This reduces downward
water pressure
and helps to minimize resuspension. |
| |
|
|
 |
|
Closed When Raising
When the bucket is raised, the vents close - reducing
the possibility of water washing material out of
the bucket. |
| |
|
|
 |
|
Drain Excess Water
Once the bucket reaches
the surface, excess water is drained through the
vents, avoiding excess dewatering costs. |
