Contoured Beam at Rear for Proper Axle Loading

This design optimizes load distribution between the axles and extends suspension life.

Durable Outrigger Attachments

Absorbs load, rather than resisting it, resulting in a longer outrigger attachment life.

Durable Suspension Design

The 4000S features optimized suspension structure, designed to minimize fatigue cracking of the main beams and suspension components for extended frame life.

Higher Quality Paint Process for Lower Life Cycle Costs

For more protection against rust and corrosion, main beam surfaces are shot blasted prior to painting with a high quality two part primer and two part urethane top coat. Interior surfaces of the main beams are painted with a durable rust preventative coating for lower maintenance costs.

Microencapsulated Adhesive on All Screws

Better and stronger connections, reducing maintenance.

Plasma Cut One-piece Main Beam Webs

For strength and durability, Utility flatbeds feature camber-shaped one-piece main beams. Our computer controlled plasma cutter creates the cambered shape into the main beam web with absolute accuracy. Utility main frame beams typically maintain more of their original shape when loaded.
