Beyer - Land-Based Bucket Chain Excavator
The land-based bucket chain excavator moves evenly along an slope on tracks during dismantling. The dredging depth is limited by the length of the bucket ladder, the sag chain, the dead weight of the dredging car and the permissible angle of slope in front of the stand.
The bucket ladder tilted downwards serves as a supporting structure, around which an endless, suspended chain moves with mounted buckets.
The excavator material is dragged upwards in the freely suspended, unguided lower mount of the bucket chain over the slope and brought to the kick-off. After the buckets have left the water, pre-drainage takes place by letting the water leave from the drainage slots provided for in the buckets. When the drop-off point is reached, the material is transferred to an intermediate silo. The bucket chain excavator can also be equipped with a dewatering device.
The conveyor chain is designed as a swastika chain.
There are slopes in a ratio of 1:3. This results in realistic excavator depths of up to 12 m, without the bucket chain excavator undermining its own stand. Removal depths of up to 14 m are possible in exceptional cases.
To enable another cut, the lane is moved inland.
If the material is not removed to stockpiles, but via a stationary landband, the loading of this strip is carried out by a swivel conveyor belt in order to enable greater extraction tunnelling without permanent reunification of the land belt.
The land-based bucket chain excavator cannot be used to deepen existing water surfaces. However, due to its stable chain guide, it can also be used in flowing waters.
