Common Features Across All Elliptical Models
Lightweight Design
Elliptical shape reduces weight while maintaining superior strength
Increased Payload
Lower tare weight allows for maximum legal payload capacity
Clean Material Flow
Curved design promotes smooth and complete material discharge
Hardox Construction
Premium Hardox steel throughout for unmatched durability
The Elliptical Advantage
Weight Savings
A curved floor carries its load in compression, so an elliptical body needs less internal bracing and fewer cross members than an equivalent flat floor model — which means less steel for the same strength.
Lower tare weight leaves more of your legal limit for payload. Exact savings depend on length, wall height and steel spec — ask Petra to weigh the two builds you are comparing.
Superior Design
The curved floor design provides excellent structural integrity while using less material, achieving the perfect balance of strength and weight.
Material flows naturally during dumping, with the elliptical shape promoting complete discharge and reducing cleanup time between loads.
