Performance Advantages

1. Maximum Payload Efficiency

The aluminum Wave construction + Wedge body allows superior cubic capacity without the extra weight of steel — perfect for maximizing loaded miles.

2. Faster Dumps & Cleaner Discharge

The Wedge taper reduces bridging and keeps your cycle times tight on busy sites.

3. Superior Strength-to-Weight Ratio

Wave sidewalls outperform traditional flat sheet aluminum thanks to:

• Internal structural webs

• Dual-wall construction

• Higher resistance to denting

• Better lifespan under abrasive materials

4. Lower Fuel Costs Over Time

A 39' aluminum end dump can save thousands annually on fuel vs. heavier steel tubs.

5. Long-Term Durability

Aluminum construction resists corrosion from aggregate dust, road salts, and general wear — stretching your ROI over years of service.

Ideal Hauling Applications

• Sand

• Gravel / aggregates

• Rock

• Demolition debris

• Asphalt / millings

• Clay / dirt

• Agricultural loads

• Waste / sludge (with liner)

• Oilfield materials

• Construction site hauling

This size and configuration is especially suited for West Texas, the Permian, construction, asphalt, aggregate quarries, and large-scale dirt work operations.
