Overview & Key Advantages
High-Strength Steel Hopper Design
Built using 10-gauge and 12-gauge steel throughout the upper and lower hoppers, supported by vertical structural bracing, this CPS design handles abrasive materials including rock, gravel, caliche, and millings. The hopper geometry includes a 54" × 108" discharge opening for fast, controlled dumps.
Precision Gate Control – Electric Over Air
This model includes a dual-mode gate control system:
Electric control from inside the cab, allowing quick, safe operation
Manual ground control for precision when needed
Integrated quick-exhaust valve for responsive gate action
23-Yard Capacity With Bang Boards
With 10" bang boards installed, the trailer offers a full 23 cubic yards of capacity — perfect for maximizing payload without creating stability issues.
K-Braced Front & Rear Ends
Both ends feature high-strength K-bracing, increasing structural stability and reducing frame flex on uneven terrain.
Certified Pushblock With Underride Protection
A fully welded pushblock provides extra strength for backing into piles or dozers, while an integrated underride guard improves safety compliance.
