Diamond Elliptical
Premium Diamond elliptical dump bodies engineered for maximum payload capacity and superior performance.
The Diamond Elliptical Advantage
Diamond Elliptical dump bodies represent the perfect balance of weight savings and durability. The curved floor needs less internal bracing than an equivalent flat floor body, allowing operators to maximize payload capacity while maintaining the structural integrity Diamond is known for.
Petra Truck Equipment provides expert installation and support for all Diamond Elliptical models. Our team ensures your dump body is properly matched to your chassis and application for optimal performance and profitability.
Key Features
Lightweight Design
Elliptical shape reduces weight while maintaining strength
Increased Payload
Lower tare weight allows for maximum legal payload capacity
Clean Material Flow
Curved design promotes smooth material discharge
Diamond Quality
Premium construction backed by Diamond excellence
Why Choose Diamond Elliptical?
Weight Reduction
A curved floor carries load in compression, so it needs less bracing than a flat floor
Structural Strength
Curved floor design naturally distributes stress throughout the body
Material Flow
Gravity-assisted discharge with curved floor profile
Lower Center of Gravity
Elliptical shape keeps load weight lower in the body
Diamond Elliptical Sizing
| Length | Typical Truck Configuration |
|---|---|
| 10' | Single axle / Tandem |
| 12' | Tandem |
| 14' | Tandem |
| 16' | Triaxle |
| 18' | Quadaxle |
| 20' | Quintaxle |
| 22' | Quintaxle |
Bodies are built from 10′ to 22′ in 6″ increments — the lengths above are common sizes, not the only ones. Cubic capacity and body weight both follow from your final dimensions and steel spec; axle configuration depends on loaded weight and your jurisdiction. Ask Petra for a weight and capacity figure on your build.
Why a Curved Floor
A curved floor carries load in compression, so it needs fewer cross members than a flat floor
Less steel for the same strength leaves more of your legal limit for payload
No corners for material to pack into, and gravity-assisted flow toward the gate
Actual weight saved depends on length, side height and steel spec. Ask Petra to weigh the two builds you are comparing rather than working from a rule of thumb.

Diamond Elliptical Frequently Asked Questions
Why choose an elliptical dump body over a flat floor?
A curved floor carries its load in compression, so an elliptical body needs less internal bracing than an equivalent flat floor model — less steel for the same strength, and a lower tare weight. They are ideal for volume hauling where material flows well and maximum legal payload matters. Ask Petra to weigh the two builds you are comparing.
What materials work best with elliptical dump bodies?
Elliptical bodies excel with free-flowing materials like aggregates, sand, gravel, wood chips, and agricultural products. The curved design promotes natural material flow. For sticky materials like wet clay or asphalt, a flat floor design may be more suitable.
How much weight can I save with a Diamond Elliptical?
Diamond Elliptical bodies typically save 400-800 pounds compared to equivalent flat floor models, depending on size and configuration. This weight savings translates directly to increased payload capacity, allowing you to haul more material per trip.
Are Diamond Elliptical bodies as durable as flat floor models?
Yes! The elliptical design actually enhances structural integrity by naturally distributing stress throughout the curved floor. Combined with quality Diamond construction and Hardox steel, Diamond Elliptical bodies provide excellent durability for long service life.
