Loose or poorly balanced cargo causes sway, blow-offs, and serious liability. Edmond Rentals does not load cargo for you — you are responsible for weight, balance, securement, and legal compliance. This guide covers limits, placement, tie-downs, and pre-trip checks for open utility trailers.
Trailer, axle, tire, hitch, and truck ratings all apply.
Heavier weight forward of the axle centerline.
Straps or chains matched to cargo weight.
Straps loosen as cargo settles.
Know your weight limits
Never exceed the lowest rating in the chain:
- Trailer GVWR (gross vehicle weight rating)
- Trailer axle and tire ratings
- Coupler, tongue, and hitch receiver ratings
- Your truck’s towing and payload capacity
| Material | Approx. weight | Notes |
|---|---|---|
| Mulch / topsoil (wet) | ~800–1,000 lb per cubic yard | Fills fast on dump/utility beds |
| Gravel / stone | ~2,400–3,000 lb per cubic yard | Easy to overload axles |
| Concrete rubble | ~2,000+ lb per cubic yard | Consider multiple trips |
| Appliance (full-size fridge) | ~200–350 lb | Secure upright; strap to frame |
| Riding mower | ~400–600 lb | Use wheel chocks + straps |
Load placement — the 60/40 rule
For most bumper-pull trailers, aim for roughly 60% of cargo weight ahead of the axle centerline and 40% behind. This keeps tongue weight in a safe range (often 10–15% of total trailer weight for bumper pulls — confirm on your trailer label).
Choosing the right tie-downs
| Gear | Best for | Working load limit (WLL) |
|---|---|---|
| Ratchet straps (1″–2″) | Most general cargo | Check strap tag — typically 500–3,333 lb WLL |
| Cam buckle straps | Light furniture, soft goods | Lower WLL; not for heavy shifting loads |
| Grade 70 chain + binder | Equipment, machinery | Match chain tag to load weight |
| Tarps / cargo nets | Loose yard waste, light debris | Prevents spillage — may be required by law |
How many tie-downs do you need?
Federal motor carrier rules require cargo securement strong enough to prevent movement in any direction. Practical guidance for renters:
- Minimum two tie-downs for many loads under 5 ft if cargo cannot shift
- One tie-down per 10 ft of cargo length (rule of thumb for long loads)
- Angle straps at 30–45° to the deck for best hold
- Attach to rated D-rings or frame points — not thin stake pockets alone
Step-by-step loading
- Park on level ground; chock trailer tires
- Load heaviest items first, forward of center
- Fill gaps with dunnage so cargo cannot slide
- Strap in opposing pairs; tighten evenly
- Tarp or net loose material if required
- Push-test cargo — nothing should shift
- Re-check straps after 5–10 miles of driving
Common load types — quick tips
Lawn mowers and small equipment
- Wheel chocks or blocks in addition to straps
- Strap to trailer tie-down points; strap over wheels or frame
Furniture and appliances
- Blankets or edge protectors prevent strap damage
- Strap through legs or frames; secure upright refrigerators against tip
Lumber and long loads
- Flag or mark overhang per state rules if material extends past trailer edges
- Multiple straps along the length
Gravel, mulch, and loose material
- Do not overfill above sidewalls
- Tarp securely — road spillage is illegal and dangerous
Good vs. bad examples
60-second pre-trip walk-around
- Total weight under GVWR and truck ratings
- Load balanced; tongue weight feels reasonable
- All straps tight; no frayed webbing or bent hooks
- Tarps or nets secure; no loose debris
- Ramps and gates latched for travel
