Ejector trailer vs Live Bottom: What’s the difference?

Comparing two non-tipping bulk-unloading systems

Ejector trailers and GINCOR Live Bottom trailers unload material without raising the trailer body. The difference is how they move the load: an ejector uses a hydraulically powered moving bulkhead to push material towards the rear, while a GINCOR Live Bottom 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. The choice depends on the material, discharge requirements, operating environment and fleet priorities.

How an ejector trailer works

Inside an ejector trailer, a hydraulically powered bulkhead moves towards the rear of the body, pushing the load out through the discharge area. The material moves horizontally, so the body remains down throughout unloading.

Ejector trailers are commonly used for asphalt, aggregate, sand, gravel, construction materials and other suitable bulk products.

How a GINCOR Live Bottom trailer works

A GINCOR Live Bottom trailer has a continuous powered conveyor belt along its floor. The belt carries material towards the rear discharge area while the body stays in its normal operating position. It can also run in reverse when the application calls for additional control over material movement.

GINCOR Live Bottom trailers are commonly configured for asphalt, aggregate, sand, gravel, roadbuilding materials and other suitable bulk products.

Live Bottom vs ejector for asphalt

Both systems can be used for asphalt transport and paving. A GINCOR Live Bottom carries asphalt towards the rear on its conveyor-belt floor; an ejector pushes it towards the rear with a hydraulically driven bulkhead. In each case, the trailer body remains down during unloading.

For asphalt work, consider:

  • Type of asphalt being hauled
  • Loading temperature and operating requirements
  • Desired discharge rate
  • Receiving equipment or paver requirements
  • Frequency of loading and unloading
  • Maintenance preferences
  • Site access
  • Overhead clearance
  • Payload requirements
  • Trailer configuration

Both systems can provide UK paving operators with an alternative to conventional tipping trailers where controlled, non-tipping discharge is required.


Live Bottom vs ejector for aggregate

Both systems may suit aggregate and bulk-material transport. A Live Bottom can carry crushed stone, sand, gravel, roadbuilding aggregate and similar bulk products. Its conveyor carries the material towards the rear while the body remains down. An ejector moves similar material towards the rear by pushing it with the internal bulkhead.

Suitability depends on:

  • Particle size
  • Material density
  • Abrasiveness
  • Moisture content
  • Required payload
  • Loading method
  • Unloading location

Why choose a non-tipping trailer?

Keeping the body down during unloading can be useful where a raised body creates additional operating considerations. Bridges, tunnels, utilities, structures and overhead lines can restrict vertical clearance. Some loading and unloading sites also have limited room for a raised trailer body.

Both systems move material progressively towards the rear, providing controlled discharge without relying solely on gravity from a raised body. Operations with frequent loading and unloading may also benefit from a purpose-built horizontal unloading system.

How walking-floor trailers compare

Walking-floor trailers are another non-tipping option. They move material towards the rear using reciprocating floor slats.

Trailer Type How It Moves the Load
Live Bottom Continuous conveyor belt
Walking Floor Reciprocating floor slats
Ejector Hydraulically powered moving bulkhead

All three systems can provide horizontal discharge, using different mechanisms.
