Trailer Types in South Africa: Which Trailer for Which Cargo

The cargo picks the trailer. Not the other way round. This is the single most useful habit for anyone entering road freight, and the most common thing new operators get backwards — buying the truck they can afford, then hunting for work it happens to suit.

This is a working index of the trailer types used in South African and SADC road freight: what each one is for, roughly what it carries, and the lengths it comes in. There are 34 of them in Kweli’s equipment catalogue, grouped into seven families. Most operators will only ever need to know three or four — but knowing which three is the whole game.

Scoping a trailer to a cargo: five questions

1. What physical form is it in? Palletised boxes, loose bulk, liquid, gas, livestock, vehicles, or something long and awkward. This alone eliminates most of the 34.
2. Does it need protection from weather, theft or temperature? Open deck, curtain, hard sides, or refrigeration.
3. How does it get on and off? Forklift from the side, crane from above, tipped out, pumped, or driven on. Loading method decides more trailer choices than payload does.
4. What does it weigh, and what does that do to your axles? Dense cargo runs out of mass before it runs out of deck; light bulky cargo does the opposite.
5. Is it regulated? Fuel, chemicals, gas and food each carry their own requirements, and the trailer is only part of what you will need.

The seven families

Dry freight — 3 types

General cargo that needs cover but not cooling. This is where most freight sits and where most operators start.

Type	Typical payload	Common lengths	What it is for
Tautliner / Curtain-side	28–34 t	6.1 m, 12.2 m, 13.6 m	Flexible curtain sides for easy side loading. Most common trailer type in SADC.
Box Body / Pantech	24–30 t	6.1 m, 8 m, 12.2 m, 13.6 m	Enclosed rigid body with rear doors. Good security for valuable cargo.
Dropside	26–32 t	6.1 m, 8 m, 12.2 m	Flatbed with hinged sides that drop down for easy loading.

The tautliner is the default South African trailer for a reason: the curtain opens the entire side, so a forklift can load anywhere along the deck rather than working from the back door forwards. That one feature is worth more in a working day than most spec-sheet differences.

Flatbed — 4 types

Type	Typical payload	Common lengths	What it is for
Flatbed / Flatdeck	28–35 t	6.1 m, 12.2 m, 13.6 m	Open platform for oversized or heavy cargo. Common for construction materials.
Lowbed / Lowboy	40–80+ t	9 m, 12 m, 15 m+	Low deck height for transporting tall machinery and abnormal loads.
Step Deck / Drop Deck	26–32 t	12.2 m, 13.6 m	Two-level deck for taller cargo without requiring oversized permits.
Extendable Flatbed	25–40 t	13.6 m – 25 m+	Telescoping deck for extra-long cargo like pipes, poles, and beams.

The step deck earns its place through a rule rather than a capability: by dropping the rear deck lower, it lets taller cargo travel under the 4,3 m height limit that would otherwise make the load abnormal and put it on a permit.

Bulk — 8 types

Type	Typical payload	Common lengths	What it is for
Tipper / Dump	28–38 t	6 m, 8 m, 10 m	Hydraulic tipping for bulk materials like sand, gravel, coal.
Side Tipper	28–38 t	6 m, 8 m, 10 m	Tips to the side instead of rear. For narrow unloading areas.
End Tipper	not recorded	not recorded	Rear-discharge tipper — sand, stone, aggregate, coal, grain.
Dropside Tipper	not recorded	not recorded	Tips like a tipper, loads from the side like a dropside.
Bottom Dump / Belly Dump	30–40 t	10 m, 12 m	Unloads through bottom doors while moving. For road construction.
Walking Floor / Live Floor	24–30 t	12.2 m, 13.6 m	Moving floor slats for automatic unloading of bulk and palletised cargo.
Hopper / Grain	30–38 t	10 m, 12 m, 13.6 m	V-shaped bottom for grain and agricultural products.
Bulk Cement / Powder	28–35 t	8 m, 10 m, 12 m	Pressurised tank for cement and other powders.

Side tipper versus end tipper is not a preference, it is a site constraint. An end tipper needs room behind it and firm level ground to raise a loaded body safely. A side tipper discharges alongside, in a windrow, which is what you want on a narrow haul road or when placing material in a line rather than a heap.

Liquid — 6 types

Type	Typical capacity	Common lengths	What it is for
Fuel Tanker	25 000–50 000 ℓ	8 m, 12 m, 16 m	For petrol, diesel, and aviation fuel. Multi-compartment.
Chemical Tanker	20 000–35 000 ℓ	8 m, 12 m	Specialised for hazardous chemicals with safety features.
Food Grade Tanker	25 000–35 000 ℓ	8 m, 12 m	Stainless steel for milk, juice, oil, wine.
Water Tanker	10 000–36 000 ℓ	6 m, 8 m, 12 m	For potable or industrial water transport.
Bitumen Tanker	20 000–35 000 ℓ	8 m, 12 m	Heated tank for hot bitumen transport.
LPG Tanker	18 000–45 000 ℓ	8 m, 12 m	Pressurised vessel for liquefied petroleum gas.

These six look alike and are not interchangeable. A food-grade tanker and a bitumen tanker are both steel cylinders on a tri-axle; one is polished stainless with a cleaning regime, the other is insulated and heated. Nobody will let you carry milk in the wrong one, and the paperwork differs as much as the steel does.

Refrigerated — 4 types

Type	Typical payload	Common lengths	What it is for
Refrigerated / Reefer	22–28 t	6.1 m, 12.2 m, 13.6 m	Temperature-controlled for perishable goods. Essential for food logistics.
Freezer	20–26 t	6.1 m, 12.2 m, 13.6 m	Deep freeze capability for frozen goods.
Insulated	24–30 t	6.1 m, 12.2 m	Insulated without active cooling. For temperature-sensitive cargo.
Curtain-side Reefer	22–26 t	12.2 m, 13.6 m	Combination of tautliner and reefer. Side loading with temperature control.

Note what the payload column does across this family: refrigeration equipment and insulation are heavy, so a reefer carries several tonnes less than a tautliner of the same length. That difference comes off your revenue on every trip.

Specialised — 7 types

Type	Typical load	Common lengths	What it is for
Car Carrier / Auto Transporter	6–12 vehicles	18 m, 22 m	Multi-level for vehicle transport. Adjustable decks.
Livestock	30–50 cattle	12.2 m, 13.6 m	Ventilated multi-deck for cattle, sheep, pigs.
Logging / Timber	30–40 t	10 m, 12 m, 13.6 m	Stakes and bolsters for logs and timber.
Pole Trailer	25–35 t	variable — extends	For long loads like pipes, poles, and structural steel.
Sugar Cane	not recorded	not recorded	Bundled sugar cane haulage, common on the KZN and Mpumalanga mill routes.
Glass Carrier / A-Frame	20–25 t	12.2 m, 13.6 m	A-frame for flat glass sheets and panels.
Horse Box	3–8 horses	6 m, 8 m, 10 m	For horse transport with stalls and living quarters.

Specialised trailers are narrow markets with fewer trucks chasing them. That cuts both ways: less competition for the work, and far less to fall back on when that work is quiet.

Container — 2 types

Type	Typical payload	Common lengths	What it is for
Skeletal / Container Chassis	30–34 t	12.2 m (40 ft), 6.1 m (20 ft)	Chassis for ISO shipping containers. Adjustable for 20 ft / 40 ft.
Tank Container / ISO Tank	21 000–26 000 ℓ	20 ft	ISO tank in standard container frame for liquids.

What the network actually runs

Thirty-four types exist. Here is what operators on Kweli Load Exchange have actually registered — real, non-test vehicles, read on 16 August 2026:

• Flatdeck — 103 · Tautliner — 89 · Tipper — 36
• Reefer — 13 · Container — 8 · Tanker — 4 · Lowbed — 4 · Car carrier — 1
• Other or not recorded — 66

Two types are two thirds of the fleet. If you are choosing a first trailer and have no specific customer in mind, flatdeck and tautliner are where the volume is — and, for exactly the same reason, where you will be one of many. The single car carrier on this network is at the other extreme.

What we do not record, and will not guess

The catalogue behind this page carries fields we have never populated: exact minimum and maximum payload in tonnes, operating temperature ranges for the refrigerated family, and whether a given trailer is certified for dangerous goods. They are empty, so nothing on this page cites them.

The payload figures above are the catalogue’s typical ranges — a planning guide, not a specification. Three types carry no figure at all and are marked as such rather than given a plausible-looking number. Your own trailer’s plate is the only payload that belongs in a quote.

Watch

• The Different Truck Trailer Types Explained — Truck Tropia. A clear visual run through trailer shapes and what each is for.

One caution before you watch. Almost all English-language trailer explainers are made for the North American market, and the names do not travel. Over there a dry van is roughly our box body, and a lowboy is our lowbed — while the tautliner, the most common trailer in this country, is uncommon enough there that it often does not appear at all. The shapes are universal; the words are not. Watch it for the shapes and use the tables above for the names.

We looked for a South African trailer-types explainer of the same quality and did not find one. That is a gap in the available material, and the sort of thing this hub exists to fill.

Questions people ask

What is the most common trailer type in South Africa?
The tautliner, or curtain-side. On the Kweli network flatdeck (103) and tautliner (89) together make up about two thirds of registered trucks. The tautliner’s advantage is that the curtain opens the whole side, so a forklift can load anywhere along the deck.

What is the difference between a side tipper and an end tipper?
An end tipper discharges to the rear and needs clear, level ground behind it. A side tipper discharges alongside the trailer, which suits narrow haul roads and placing material in a line rather than a heap. It is a site constraint, not a preference.

How much can a tautliner carry?
Typically 28 to 34 tonnes, in 6.1 m, 12.2 m and 13.6 m lengths. That is a planning range from our catalogue — your own trailer’s plate and your axle loading decide the real figure.

Why does a reefer carry less than a tautliner?
The refrigeration unit and the insulated body are heavy, so a reefer of the same length typically carries 22 to 28 tonnes against a tautliner’s 28 to 34. That difference comes off your payload on every trip.

Which trailer should I buy first?
Work from the cargo backwards. Establish what you will haul and for whom, then pick the trailer that suits how that cargo is loaded and protected. A confirmed customer with regular work beats a more capable trailer with none.
