4-Axle U-Type Rear-Tipping Trailers for a Quarry Hauler in Uzbekistan

A U-Shaped Body for Loose Aggregate

A quarry and aggregate hauler in Uzbekistan needed a rear-dump tipping trailer for sand and gravel work, and specified the U-shaped body over a flat box profile — the curved floor sheds loose material cleanly on the tip rather than leaving debris packed into square corners.

4 Axles Instead of the Standard 3

SIGMA's standard build for this trailer runs a 3-axle bogie, but this order called for a 4-axle configuration to match the customer's route weight limits and gross combination rating. Adding the extra axle spreads the loaded weight further along the frame, which matters on a haul road that sees the same route run dozens of times a day.

Wear-Resistant Body for the Duty Cycle

The body combines Q345B structural steel with a Hardox wear-resistant floor liner, built for a quarry haul cycle rather than occasional use. A front-mounted hydraulic cylinder lifts the body to a 45-degree dump angle in under 25 seconds, keeping the truck's turnaround at the pit short.

Finished Units Ready for Loadout

The batch photographed clean at the rear three-quarter angle before loadout, U-type bodies down and axles square, ready to be coupled to tractor units for the export run to Uzbekistan.

Quarry to Road-Building Duty in Uzbekistan

Aggregate hauled from pit to road-building site benefits most from a short tip cycle, since a truck sitting at the discharge point longer than necessary is time it isn't spending back at the quarry loading the next run.
