NMFC 189600: Straddle Trailers w/ Hyd Lift | Class 100

To find the correct freight class for your shipment:

1. Confirm each unit weighs 5,000 lb or more and list NMFC 189600, Class 100 on the BOL. Include certified weight and note non-stackable status.
2. Choose the right equipment for height and wheel spread. Many straddle trailers ride tall—use step-deck or lowboy if over 102 in height to avoid over-height charges.
3. Prep hydraulics before pickup: retract lift arms, engage mechanical locks, cap and protect hose ends and manifolds, and shield the control box to prevent impact or oil seepage.
4. Secure via the structural frame using rated chains or straps at four corners. Block wheels, chock as needed, and avoid tying down to hydraulic cylinders or lift components.

Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.

• Class 100, weight-governed rating reduces density disputes, preventing costly reclass fees and billing delays.
• Clear eligibility (≥5,000 lb each) streamlines quoting across carriers, improving rate consistency for capital equipment moves.
• Proper equipment selection (step-deck/lowboy) avoids over-height or specialized handling surcharges, lowering total landed cost.
• Protecting hydraulic systems cuts damage claims and downtime, keeping mission-critical material handling assets in service sooner.
