We explain the essentials straight away: correct placement of weight and secure tie-downs prevent accidents and damage on Adelaide roads. Our guide shows practical steps for steady towing, protecting cargo and keeping your vehicle and family safe.
We build and service trailers that tow straight and last, so we speak plainly and share checks we use in our workshop. Park level, chock wheels, and position heavy items just forward of the axle for a roughly 60/40 split of mass front to rear.
Tie down from multiple angles with rope, chain or ratchet straps and tidy excess webbing. Hitch up properly, cross safety chains and test lights and brakes before you set off. For tandem setups, keep 10–15% of gross trailer weight on the tongue to cut sway.
Our team in Adelaide backs these steps with quality materials, routine safety checks and custom builds. Need help or a custom setup? Call 0447 100 145, request a quote, or book a service with Smooth Moves Trailers. We’ll make sure your trailer is ready to head home.

Why safe loading matters on Adelaide roads
Adelaide’s roads test every tow. Windy coastal stretches, steep descents and stop‑start suburban traffic create hazards that poor packing makes worse.
We keep this practical: start on level ground, chock wheels and plan for roughly 60% of the mass just forward of the axle. That distribution reduces sway and shortens stopping distance.
Unsecured loads can fall and cause accidents or serious damage to other vehicles. The law also requires that loads are secured and that you do not exceed ratings.
- Balanced weight cuts wear on springs, bearings and tyres and saves downtime.
- Proper tie‑offs stop toolboxes, bricks and landscaping materials shifting under braking.
- Quick pre‑trip checks — pressure, lights, brakes and chains — take minutes and prevent hours of delay.
We recommend quality straps and routine servicing. If you carry loads often, call 0447 100 145 for an inspection and advice on the best way load and hardware for your trailers and trailer use.
How to load a trailer safely: step-by-step
We walk through each step with clear checks and workshop-tested tips. Follow this short sequence before you move off. Each task takes minutes and prevents major problems on Adelaide roads.
Know limits and set up
We weigh cargo, check the towing vehicle rating and the trailer GVWR, then subtract tare to find usable capacity. Park on firm, level ground and chock the wheels.
Position and pack
Plan a 60/40 rule with 60% of mass forward of the axle. Place heavy items first, just forward of the axle. Keep weight low, fill voids and stack light items only when stable.
Secure and hitch
Use quality straps, ratchet gear and anchor points. Tie down from multiple angles and tidy excess. Cover loose cargo with a net or tarp.
Final checks: seat the coupler, cross safety chains, plug in lights and perform a brake test. For tandem units, confirm tongue weight at 10–15% of gross mass. For anchor points or gear, call 0447 100 145.
| Step | Action | Why it matters |
|---|---|---|
| 1 | Check ratings | Prevents overload and wear |
| 2 | Chock & level | Stops roll and eases placement |
| 3 | 60/40 distribution | Reduces sway and improves braking |
| 4 | Secure with straps | Keeps cargo from shifting |
Weight distribution made simple for single, tandem and flat top trailers
We set out clear placement rules so loads track true and steering stays positive. Our focus is stability, tyre life and predictable handling for each trailer type we build and service.
Single axle units
Place the heaviest items just forward of the axle. Aim for roughly 60% of the usable weight in front of the axle line to keep the coupling loaded and tracking straight.
Tandem axle setups
Follow the same 60/40 rule across the set and verify tongue weight at about 10–15% of gross mass. Regular checks keep sway low and steering responsive.
Flat top configurations
Keep the centre of gravity low and pack tightly. Centre dense items near the front trailer axle and avoid tall stacks that catch wind and shift the weight up top.
- Even side-to-side distribution reduces tyre wear and bearing stress.
- For long loads we add extra lashing points that match the axle trailer geometry.
- Ask us about suspension or brake upgrades and custom tie-down rails — call 0447 100 145.
| Type | Front weight target | Key tip |
|---|---|---|
| Single axle | ~60% front | Place heaviest items just ahead of axle line |
| Tandem axle | 60/40; tongue 10–15% | Check tongue weight and balance across axles |
| Flat top | Low, centred | Pack tight; add lash points for long loads |
Securing your load: straps, tie-down points and weather protection
We fit rated anchor points and show simple tie patterns that keep gear locked in place. Start by choosing tie-downs with a working load limit above the cargo mass so you have reserve strength in sudden stops.
Ratchet straps and anchor points
Use certified ratchet straps over heavy machinery and pallets. Tie patterns should pull from opposing angles to clamp items to the deck and stop forward or sideways shift.
Tarps and cargo nets
Cover loose cargo with a net and add a tarp for weather protection. Tarps are waterproof and mildew resistant; nets hold irregular items and prevent gusts from lifting the top layer.
Protective pads and wrap
Place pads between sharp edges and straps to avoid damage. Wrap doors and drawers so nothing swings open in transit and so finishes stay intact.
- Practical tips: tie off excess webbing away from wheels and road.
- Sweep the deck and ground so friction helps the lashings.
- For flat top work we fit low, tight lines that keep the centre of gravity down.

Mistakes that cause sway, damage and downtime
A few common faults are the main causes of sway and component failure on the road. We see them every week in our Adelaide workshop and on roadside call‑outs. Noticing these issues early saves time and money.
Overloading and poor placement top the list. Exceeding the maximum weight limit cracks springs, overheats bearings and leads to tyre or hub failure. Placing heavy items at the rear reduces weight front at the coupling and invites sway at highway speed.
Loose gear and messy straps
Worn or wrong straps let cargo move and can abrade sharp edges. Untidy excess webbing sometimes reaches the wheels. Always tidy tails and use rated straps for heavy items.
- Skip chocks during loading and the trailer can roll and cause injury.
- Ignore lights and brakes and you risk fines and night‑time hazards.
- Wrong way load—tall stacks—raises the centre of gravity and increases rollover risk.
| Fault | Effect | Common fix | Preventive habit |
|---|---|---|---|
| Exceeding GVWR | Cracked springs, overheated bearings | Replace springs, inspect hubs | Weigh cargo before loading |
| Rear‑heavy load | Sway at speed | Reposition items forward | Follow the 60/40 rule |
| Loose straps | Cargo movement, wheel contact | Fit new ratchets and pads | Tidy and double‑check lashings |
| Skipped checks | Fines, collisions at night | Repair lights and brakes | Test lights and brakes every trip |

FAQ
What vehicle and trailer limits should we check before loading?
We verify the towing vehicle’s tow rating, the trailer’s GVWR and the safe tongue weight. Consult the vehicle handbook and the trailer plate. Never exceed either limit — doing so risks brake failure, axle damage and accidents.
Where should we park the trailer when preparing a load?
We always use level ground, apply the trailer handbrake, chock the wheels and engage wheel stabilisers. This prevents rollaway and makes it safer to move heavy items on and off the deck.
How do we decide which items go near the axle?
We place the heaviest items just forward of the axle or axles. For single-axle units that means slightly ahead of the wheel; for tandem axles follow the 60/40 guideline with more weight forward to maintain adequate tongue load.
What is the 60/40 rule and why does it matter?
We use the 60/40 split to keep the centre of gravity forward — roughly 60% of the mass ahead of the trailer axle(s) and 40% behind. This reduces sway and protects the towing setup from overload and instability.
How should we stack lighter items and fill gaps?
We keep weight low and compact, place lighter items on top, and use smaller boxes or soft fill to remove voids. Tight packing lowers the centre of gravity and stops cargo shifting under braking or cornering.
Which tie-downs and patterns give the best security?
We favour ratchet straps rated for the load’s working load limit. Use multiple tie points and cross straps where possible to prevent longitudinal and lateral movement. Avoid knots in webbing; use approved fittings and check for wear.
When should we use tarps, nets and protective padding?
We apply tarps and cargo nets when weather or road debris is a risk, and use padding where straps contact delicate surfaces. Proper covers also reduce wind drag and the chance of unexpected loss on highways.
How do we check tongue weight accurately?
We use a commercial tongue weight scale or a calibrated load cell. Aim for the manufacturer’s recommended percentage of the gross trailer mass — usually 7–10% for many setups — and recheck after minor adjustments.
What common mistakes lead to trailer sway or damage?
We see problems from overloading, poor fore-aft distribution, loose straps and excess strap slack flapping in the wind. Ignoring tyre pressures, worn bearings or incorrect hitch settings also causes instability.
How should we hitch and test before departure?
We couple the ball and socket correctly, attach crossed safety chains, plug in lights and test indicators, tail lights and brake function. Do a short roll-and-brake test in a safe area to confirm handling before hitting main roads.
What maintenance or checks should we do regularly?
We inspect tyres for correct pressure and tread, check wheel bearings, confirm secure tie-down anchors and examine straps for cuts or UV damage. Regular servicing of brakes, suspension and the coupling is essential.
When should we contact professionals for custom setups?
We recommend expert help for non-standard loads, heavy machinery, customised tie-down frames or if modifications to the trailer or vehicle are needed. A qualified rigger or accredited trailer service can design safe solutions.
Are there legal requirements we must follow on South Australian roads?
We comply with state regulations on maximum axle loads, overall mass limits and load restraint standards. Always check the latest South Australian Department for Infrastructure and Transport guidance for legal limits and penalties.
