A single-axle livestock trailer is a 3 m stock body on one axle, built for sheep, goats, pigs and calves. Sides run to 2.2 m on a 50 x 50 mm square-tube frame, and the trailer is available braked or non-braked depending on what you tow with.
Most smallholders and farmers moving small stock do not need a tandem trailer, and buying one costs them fuel and manoeuvrability every trip. A 3 m single-axle body carries a working load of small stock, hitches to a standard bakkie, and turns in a kraal gateway that a 5 m trailer cannot.
The body is where the money goes. Sides at 2.2 m are high enough that nothing gets a leg over the top rail. Square-tube framing on close spacing stops a lamb pushing through while still moving air through the load, which matters when you are standing in a queue at a weighbridge in January. The floor is laid for grip rather than for looks, because an animal that slips takes the whole load down with it.
Gates are specified for one-person work. Combo swing gates let you open the back partially and work from the side, and a centre dividing gate lets you split the load or hold a single animal in half the space so it cannot build momentum.
The non-braked version stays inside the 750 kg towing class. The braked version runs a 1,500 kg braked square axle with a two-tonne coupler, which is the one to choose if you regularly load to capacity or if your route home is downhill.
For cattle, game and bigger loads, the tandem-axle livestock trailers cover 4 m and 5 m bodies to 3,000 kg GVM.
