This video shows the process of manually transferring wet river sand from shallow water into a dump truck bed. A worker uses a shovel to scoop sand from the riverbed and load it into a waiting vehicle for transport.

Technical Principles & Material Handling

The sand loading process uses simple manual tools to move bulk material from its natural source to a transport vehicle. Its functional mechanism can be understood in three key aspects:

First, the shovel blade penetrates the riverbed to scoop sand. The moisture content increases the material’s weight and cohesion, making it heavier and slightly more compact than dry sand.

Second, the lifting motion transfers the load from water level up to the height of the dump truck bed, requiring significant physical effort and balance.

Third, through repeated cycles, the worker gradually fills the truck to the required capacity for transport to a construction site or processing area.

From a logistics perspective, this manual method is a low-cost extraction solution, especially suitable for small-scale operations or areas where heavy machinery cannot access. The entire technique relies primarily on human labor for material movement.

Step-by-Step Loading Procedure

Positioning Stage:
The worker stands in shallow water within shoveling distance of the truck’s rear loading area.

Scooping Action:
The shovel is pushed into the riverbed, collecting a mixture of sand and water.

Lifting and Transfer:
The loaded shovel is lifted out of the water and swung or raised to pour the material into the truck bed.

Repetition:
The process continues until the desired load level or collection target is reached.

Key Features & Advantages

Accessibility:
Manual loading allows access to locations where heavy equipment cannot operate due to terrain or water depth limitations.

Low Capital Requirement:
No machinery investment is needed, making it ideal for small contractors or local operators.

Selective Collection:
The worker can visually inspect sand quality during loading and remove unwanted debris.

Important Construction Considerations

Ergonomics:
Proper lifting techniques are essential to reduce the risk of injury during repetitive heavy loading tasks.

Moisture Content:
Wet sand is significantly heavier than dry sand, affecting load calculations and transportation planning.

Truck Positioning:
Keeping the truck close to the water source minimizes shoveling distance and maximizes efficiency.

Environmental Impact:
Manual extraction generally causes less environmental disturbance compared to mechanical dredging operations.
