A jockey wheel or trailer jockey is an easy-to-use, self-contained device primarily designed for lowering and raising the coupling end of a trailer and for stablekeeping the trunk of the trailer while towing it to and from another vehicle. It really is used to reduce the strain on the trailer’s tow-line. jockey wheel clamp is the device that raises and lowers the trailer, using a hydraulic system. A jockey wheel acts as the "punch" arm by raising and lowering the trailer with its crankshaft. The trailer is then moved together with the crankshaft of the trailer by the towing arm. Jockey wheels can be either directly or indirectly driven; the latter type of wheel is more regularly used.

There are various forms of jockey wheels, each suitable for particular circumstances. You can find basically two types: straight shafts and counter-rotating shafts. They differ regarding design, size, type of material used and the direction they are fitted. The most frequent types of trailer jockey wheels will be the straight shafts and the counter-rotating ones. The straight shafts feature a single large counter-rotating arm that is placed in the biggest market of the wheel, which has a cross bar attached at another end.

These arms are connected by a large number of smaller arms that are fitted at the ends of the primary body. All the arms have a cross bar attached in order that the upper surface of the wheel could be lifted by it easily. Alternatively, the counter-rotating ones feature an arched design with a series of vertically mounted clamp brackets round the outside of the arm. These are fitted over the trailer jockey wheels and engage the wheels at their ends. Clamp brackets are also used in tandem with the jockey wheels to lock the trailer securely in place.

Mounting brackets, in turn, are made out of different materials. A number of them are created out of steel, while some are created out of aluminum or plastic. The former is more preferable since it is more durable and is light-weight; as the latter can be cast, but is comparatively expensive. You should choose the mounting bracket which will work best with the trailer. However, all jockey wheels and mounting brackets are not too difficult to set up on trailers of any kind, irrespective of the type of vehicle they’re destined to be used on.

The next phase entails mounting the wheel on the trailer, where it’ll engage the trailer’s winch system and the cable ties. At this time, installation of windshield or roof shingles should come in to the picture. Next, the cable will run from the winch to a cable trimmer to the wind shield and finally to a cable cutter to perform the job.

Once installed, it is advisable to practice driving the vehicle without the load on it for a few days to ensure that the device is in perfect working condition. Alternatively, when going over rough and uneven surfaces, it’s important that you utilize pneumatic tires because they offer better traction on soft and muddy ground. Aside from utilizing the appropriate jockey wheel on the trailer, it is also important to make use of a jack to raise the vehicle to a working level. Ensure that the vehicle is raised utilizing the right method – usually utilizing an extension ladder – and is maintained properly in order not to cause damage to the vehicle or its components when raising it. Finally, be sure you drive the vehicle slowly and cautiously over the rough surface, taking care never to step on the gas or the brake pedals.
