Flexible Load Heights – Ratchet neck and multiple fifth-wheel settings allow height customization.
Low Transportation Profile – Deck heights from 18″–24″ maintain overall transport clearance for oversized loads.
Structural Strength – Full-depth frames, cambered beams, Apitong decking, and outriggers ensure load stability.
Safety Built-in – Positive-lock pins, alignment guides, scraper-style necks, and self-locking systems offer secure, reliable hook-ups
Capacities include 55 ton (110,000 lb), 60 ton (120,000 lb), 65 ton, and 75 ton with concentric load ratings at 12′ load zone.
