Working Principle
The operating principle is relatively straightforward.
Step 1: Loading
Bulk materials are loaded into the cargo body.
Step 2: Transportation
The trailer transports materials to:
- Construction sites
- Mining sites
- Grain facilities
- Industrial areas
Step 3: Hydraulic Tilting
The hydraulic cylinder raises the front section of the trailer body.
This creates a tilting angle.
Step 4: Automatic Unloading
Gravity allows materials to slide out from the rear gate automatically.
The sloped wall structure helps prevent material sticking.
Step 5: Lowering the Cargo Body
After unloading:
- Hydraulic pressure lowers the body
- Trailer returns to transportation mode
Entire unloading process usually takes only minutes.
