Скачать или смотреть Excavators dredged pebbles from the river onto boats—to improve water flow.

The video shows an excavator on a boat dredging pebbles from the river onto the vessel. This is a common operation in water engineering, primarily used for sand and gravel transportation or river dredging. Here are the specific procedures and precautions: The excavator must be secured to the boat via a ship-mounted platform or floating work platform to ensure equipment stability.

The boat must remain balanced to prevent tilting due to excavator operation. The excavator arm extends into the water, grabbing pebbles from the riverbed and transferring them to the boat's storage compartment. The boat is equipped with an unloading device to unload the pebbles at a designated location. During transport, the boat speed must be controlled to prevent cargo swaying. To avoid damaging the riverbed ecosystem, the site must be cleaned up after operation. Operations should be suspended during severe weather (such as strong winds or heavy rain) to ensure the safety of personnel and equipment. The pebbles are used in breakwater or bank protection projects. Removing silt improves water flow.
