What is a jockey wheel and what is it used for?

A jockey wheel is a support wheel fitted to the front of a trailer or caravan. It is used to stabilise the trailer when it is uncoupled from a towing vehicle, and to manually manoeuvre the trailer into position. The wheel can typically be raised or lowered via a clamp mechanism to suit the required height.

What is the maximum load this jockey wheel can support?

This jockey wheel has a rated load capacity of 400kg. This makes it suitable for heavy trailers, large caravans, and substantial mobile equipment. Always ensure the load applied does not exceed this rated capacity to maintain safe operation.

What shaft diameter does this jockey wheel use, and will it fit my trailer?

The shaft diameter is 60mm. Before purchasing, please verify that your trailer's clamp or mounting bracket is compatible with a 60mm shaft. This is a common size used across a wide range of trailer and caravan applications, but it is always advisable to confirm your existing fitting dimensions.

Can this jockey wheel be used on uneven or outdoor surfaces?

Yes. The 255mm rubber tyre is specifically suited to outdoor use on a variety of surfaces including concrete, tarmac, compacted gravel, and firm ground. The larger wheel diameter helps to roll over minor surface irregularities more smoothly than smaller wheels, making it a practical choice for outdoor yards, farms, and construction environments.

Why is the wheel diameter important when choosing a jockey wheel?

Wheel diameter directly affects rolling performance and surface compatibility. A larger diameter wheel — such as this 255mm model — distributes load more effectively, rolls more easily over surface imperfections, and reduces the effort required to manoeuvre heavy loads. It also contributes to the overall height of the assembly, which is an important consideration when matching the jockey wheel to your trailer's coupling height.

What does the total height of 720mm refer to?

The total height of 720mm refers to the overall assembled height of the jockey wheel unit from the ground contact point of the tyre to the top of the shaft. This measurement is important when assessing whether the jockey wheel will provide sufficient height range to support and level your trailer or caravan at the required coupling height.
