LW Bucket Ladder Dredge or Bucket Chain Dredger is a stationary dredger, which has an endless chain of buckets carried by the so-called ladder.

LW Bucket Ladder Dredge or Bucket Chain Dredger is a stationary dredger, which has an endless chain of buckets carried by the so-called ladder, positioned in the well of pontoons. The chain is driven by the upper tumbler, a pentagonal, at the upper part of the ladder and fixed at the bottom with lower tumbler, mostly a hexagonal. Under the ladder the chain hangs freely, while on the upper site of the ladder the chain is supported and guided by rollers. The buckets filled during their rotation over the lower tumbler are emptied by the rotation over upper tumbler. The soil from there guided via chutes to an alongside layer barge or by long-distance relay conveying system.

Bucket sizes vary from 30 liters to 1200 liters. Rock bucket dredgers do have a double set of buckets; a small rock bucket and a bigger soft soil bucket.

Area of application

The Bucket Dredger can be applied in almost all soils, from soft silt and clays to soft rock depending on the power on and the strength of the bucket chain. They are use in blasted rock as well.

The maximum dredging depth depends on the size of the dredger. Bucket Ladder Dredgers with a maximum dredging depth of over the 30 m are built.

However for such dredgers the minimum dredging depth is almost 8 m.

Nowadays they are often used for dredging contaminated mud, because they can dig the soil under in situ density conditions.

The Bucket Ladder Dredge can not apply under offshore conditions and is certainly an obstruction for shipping. Compared to hydraulic dredgers, its production is rather low.
