Walking Floor vs Live Bottom Trailer: What’s the Difference?
Comparing Two Non-Tipping Bulk-Unloading Systems
Walking-floor and GINCOR Live Bottom trailers both unload bulk material without raising the trailer body. The difference is how they move the load.
A walking-floor trailer uses hydraulic floor slats that move backwards and forwards in sequence, gradually shifting material towards the rear. A GINCOR Live Bottom trailer uses a continuous powered conveyor belt built into the floor to carry material towards the discharge area.
Both systems can handle demanding bulk-hauling applications, including asphalt and aggregate. Choosing between them depends on the material, discharge requirements, operating environment and fleet priorities.
How a walking-floor trailer works
A walking-floor trailer, also called a moving-floor trailer, has groups of narrow, hydraulically powered floor slats.
During unloading, the slats move together in the discharge direction. They then retract in smaller groups while most of the floor holds the load in place. This sequence repeats, gradually moving material towards the rear without raising the trailer body.
Walking-floor systems are widely used to transport:
- Aggregate
- Asphalt
- Biomass
- Waste and recycling materials
- Agricultural products
- Wood products
- Other loose bulk materials
How a GINCOR Live Bottom trailer works
A GINCOR Live Bottom trailer has a continuous conveyor belt running along the bottom of the trailer. During unloading, the powered belt carries material towards the rear discharge area while the body stays in its normal operating position.
The conveyor can also run in reverse when the application requires additional control over material movement.
GINCOR Live Bottom trailers are commonly configured to carry:
- Asphalt
- Aggregate
- Sand
- Gravel
- Roadbuilding materials
- Other suitable bulk products
Walking floor and Live Bottom compared
| Comparison Point | GINCOR Live Bottom | Walking-Floor Trailer |
|---|---|---|
| Unloading mechanism | Continuous powered conveyor belt | Reciprocating hydraulic floor slats |
| Trailer body during unloading | Remains down | Remains down |
| Material movement | Belt continuously carries material towards the rear | Slats move material towards the rear through a repeating sequence |
| Discharge type | Controlled horizontal discharge | Controlled horizontal discharge |
| Floor design | Continuous belt system | Multiple moving slats |
| Reverse operation | Conveyor belt can run in reverse | Depends on the system and configuration |
| Typical applications | Asphalt, aggregate, sand, gravel and other bulk materials | A broad range of bulk materials, including aggregate, biomass, waste and agricultural products |
| Suitability | Depends on the material, discharge requirements and operating environment | Depends on the material, discharge requirements and operating environment |
With a Live Bottom, the load travels along with the belt surface. A walking floor shifts the load through the repeated movement of its slats. Both provide horizontal unloading through different mechanical systems.
Live Bottom vs walking floor for asphalt
Both technologies can transport asphalt. For paving operations, the ability to unload with the trailer body down and maintain controlled discharge is often an important requirement.
A GINCOR Live Bottom carries asphalt towards the rear on its conveyor belt. An appropriately configured walking-floor asphalt trailer moves it using reciprocating slats.
When comparing the two, consider:
- The type of asphalt being hauled
- Loading temperature and operating requirements
- Desired discharge rate
- Paver or receiving-equipment requirements
- Frequency of loading and unloading
- Maintenance preferences
- Site access
- Overhead clearance
- Trailer configuration
For UK roadbuilding operations focused on asphalt, a purpose-built Live Bottom configuration may be worth considering alongside walking-floor and ejector systems.
Live Bottom vs walking floor for aggregate
Both systems may also suit aggregate transport.
A Live Bottom can carry and discharge crushed stone, sand, gravel, roadbuilding aggregate and similar bulk materials. Its conveyor floor moves the load towards the rear discharge area with the trailer body down.
Walking-floor trailers can also handle many bulk materials. The suitability of either system depends on:
- Particle size
- Material density
- Abrasiveness
- Moisture content
- Required payload
- Loading method
- Unloading location
Why choose a non-tipping trailer?
Keeping the trailer body down during unloading can be useful where clearance or space is limited.
Bridges, structures, tunnels, utilities and overhead lines can restrict vertical clearance. Confined loading and unloading areas may also leave little room for a raised trailer body.
Walking-floor and Live Bottom systems move material progressively, giving operators controlled discharge without relying solely on gravity from a raised body. Operations with frequent loading and unloading may benefit from a purpose-built horizontal unloading system.
How ejector trailers compare
An ejector trailer is another non-tipping option. It uses a hydraulically powered bulkhead to push material towards the rear.
The three systems use different mechanisms:
| Trailer Type | How It Moves the Load |
|---|---|
| Live Bottom | Continuous conveyor belt |
| Walking Floor | Reciprocating floor slats |
| Ejector | Hydraulically powered moving bulkhead |
