Turn cargo and device details into a useful pre-dispatch conversation—without mistaking a raw WLL total for a securement design or compliance decision.
In This Guide
What It Means
A flatbed securement worksheet inventories cargo, proposed trailer context and available devices before dispatch. It helps the shipper, dispatcher, carrier and loading team expose missing information early. It is not a securement design, inspection or safety or compliance determination.
The OTR Flatbed Load Securement Planner multiplies quantity by weight per item and device count by entered per-device working load limit (WLL). It compares the raw device sum with full cargo weight. Dimensions, trailer type and orientation are context only; the tool does not calculate geometry, restraint forces or a device arrangement.
A device rating is only one part of the system: the load path also includes tensioners, connectors, cargo attachment points and trailer anchors, plus arrangement and commodity-specific rules. Arithmetic can prompt questions, not answer them.
Why It Matters
Dispatch delays can start with a guessed item weight, an unmarked strap, an unknown anchor rating, an unsuitable contact point or missing commodity instructions. An early inventory gives the carrier concrete details to verify.
- Documented quantity and weight support planning but do not replace weighing or applicable weight checks.
- Check device markings, condition and compatible hardware before the truck arrives.
- Gather commodity instructions and list unknowns for carrier review before dispatch.
How It Works
Build the inventory before choosing a setup
Record commodity, piece count, documented weight per piece, dimensions, packaging, centre-of-gravity concerns, loading method and shipper or manufacturer instructions. Keep units consistent. Note proposed trailer and orientation as context, then inventory device type, marked rating and condition. Add connector, tensioner, cargo attachment and anchor information where available; a count and label do not describe the assembly.
Treat outputs as arithmetic prompts. Comparing raw entered device WLL with full cargo weight is not the statutory aggregate-WLL test in either country. U.S. FMCSA general rules include an aggregate tiedown WLL criterion generally based on at least one-half of the article’s weight, alongside other requirements. Canada’s NSC Standard 10 is adopted through provincial and territorial frameworks. Neither a full-weight screen nor a passing result establishes compliance; check the actual route and commodity provisions.
Hypothetical example: useful arithmetic, incomplete evidence
Suppose a fictional shipment has 8 crates entered at 2,500 lb each: 8 × 2,500 = 20,000 lb total. The planner is also given 6 devices at an entered 4,000 lb WLL each: 6 × 4,000 = 24,000 lb raw sum. The worksheet comparison would show 24,000 lb is greater than the 20,000 lb cargo total. Those figures are invented solely to explain the arithmetic; they are not a recommendation, a device count, or a result from a customer shipment.
The example leaves key facts unanswered: are ratings legible; what are connector, tensioner and anchor ratings; what are the actual paths and angles; are devices direct or indirect; can cargo attachment points take the loads; is the freight stable; and do route or commodity rules add requirements? A weak component or unsuitable geometry can limit the system. The carrier must review the actual load and configuration.
Common Challenges
- Mixing pounds and kilograms, or inches and centimetres, makes totals misleading.
- Treating a device label as the assembly rating. U.S. 49 CFR 393.108 uses the lowest-rated tiedown component or anchor; check the applicable rule and full assembly.
- Assuming a larger raw sum compensates for weak anchors, poor angles, damaged devices or unstable cargo.
- Assuming dimensions and trailer selections mean fit, axle loading or geometry was assessed; it was not.
- Overlooking commodity-specific requirements or manufacturer instructions.
A raw sum below cargo weight is not a non-compliance finding: the worksheet models neither the legal test nor full system. Either result is a prompt to verify, not a green light or violation notice.
Best Practices
- Confirm piece count, weight, packaging and dimensions with the shipper; label estimates clearly.
- Record device markings and condition; confirm compatible hardware and anchor ratings with the carrier or manufacturer.
- Share instructions early for machinery, lumber, coils, pipe, vehicles and other specialized commodities.
- Have a qualified carrier reviewer examine the real load path, angles, arrangement, contacts, blocking, edge protection, dunnage and stability.
- Identify route jurisdictions and check current general and commodity rules; adoption and enforcement details can differ.
- Label the worksheet preliminary and revise it if cargo, equipment or loading conditions change.

When to Use This Service
Use this worksheet to organize cargo, trailer context and available-device information before booking, a loading discussion or carrier review. It does not replace the loading plan, inspection, engineering advice where needed, or the carrier’s determination under applicable requirements.
For a separate, more guided advisory workflow, the OTR Hub Load Securement Planner collects additional cargo and setup information. It is also preliminary—not final legal approval, a securement design, or a safety determination.
Use the matching Flatbed Load Securement Planner to organize cargo details and available-device ratings in its pre-dispatch worksheet. Its raw comparison is advisory only and does not determine whether a load is safe or compliant.
Frequently Asked Questions
Does a raw WLL sum greater than cargo weight prove that the load is adequately secured?
No. The planner compares only device-count × entered WLL with full cargo weight. It omits weakest components and anchors, geometry, angles, load paths, condition, cargo attachment points, stability and commodity rules. The actual system still needs qualified review.
Does a raw sum below full cargo weight mean the shipment is non-compliant?
No. This is neither the statutory test nor a compliance finding. Rules vary by jurisdiction and cargo; U.S. FMCSA general rules use an aggregate tiedown-WLL criterion generally based on one-half cargo weight, alongside other requirements. Verify the rules and setup.
Why do anchors and connections matter if the straps have a marked WLL?
An assembly is limited by its components and attachment points, not simply a strap label. U.S. 49 CFR 393.108 uses the lowest WLL among components or anchor points, whichever is less. Confirm all ratings under applicable rules and manufacturer instructions.
Does the planner assess dimensions, trailer choice or load orientation?
No. They preserve planning context. The tool does not test trailer fit, weight distribution, axle loads, cargo geometry or orientation suitability; review these against the real equipment, load and route.
Which securement standard applies to a Canadian–U.S. flatbed move?
Do not assume there is one universal regime. U.S. operations are subject to applicable FMCSA regulations; Canada’s NSC Standard 10 is a model standard adopted through jurisdictional frameworks. Check the rules applicable to each part of the route, the carrier and the commodity, including local adoption or additional provisions.
