Jockey wheel with cast iron clamp KNOTT TK48+LBG48 150kg 48mm 500-720mm

Jockey wheel with cast iron clamp KNOTT TK48+LBG48 150kg 48mm 500-720mm

A complete KNOTT set including a solid jockey wheel, a dedicated clamp and the necessary mounting elements , ensuring stable and safe support for the trailer while parking, maneuvering and connecting to the towbar.

The set includes:

• 1x TK48 support wheel
• 1x LBG48 cast iron clamp (clamp) for the jockey wheel
• 4x M10x25 screw
• 4x self-locking nut M10

The TK48 support wheel is equipped with a tube with a diameter of 48 mm and a total height of 500 mm including the wheel , which ensures a solid, stable structure and comfortable work.

The LBG48 cast iron clamp (clamp) with a 48 mm pipe diameter ensures stable and secure attachment to the trailer drawbar. The clamp is 142 mm long and 77 mm wide , ensuring adequate clamping surface and solid pipe retention. It is equipped with six 11 mm diameter mounting holes with a 105 x 50 mm spacing, allowing for easy and precise installation to the trailer structure.

The jockey wheel and clamp kit is a practical and reliable solution designed to stabilize the trailer when parked and facilitate maneuvering and rolling it around the yard , driveway, campsite, or workshop. It allows for convenient connection and disconnection of the trailer from the towbar and precise positioning. The jockey wheel stabilizes the trailer but is not intended for lifting it with a load . The clamp, however, is a key mounting element, ensuring a stable and secure attachment of the tube to the drawbar and its secure positioning. This combination increases the comfort and safety of transport, boat, and caravan trailers, guaranteeing durability and solidity of the structure. For safety reasons, check the lever pressure and condition of the jockey wheel tube before each ride.

Permissible load

The permissible load when parked is 150 kg , providing stable and safe support for the trailer during loading, unloading, and extended periods of standstill . A properly selected load capacity ensures reliable support for the drawbar, reduces the risk of tilt, and improves comfort when working around the trailer. Maintaining the maximum load limits is crucial for maintaining the durability of the mechanism, protecting structural components from overload, and ensuring long and trouble-free product operation. .

Extension length

The support wheel extension is 220 mm , providing a suitable range of drawbar height adjustment. The height with the wheel is 500 mm, and the maximum height with extension reaches 720 mm . This range allows for convenient adjustment of the trailer to various ground conditions and facilitates connecting and disconnecting it from the tow bar, increasing comfort and stability when parked.

Type of wheel

The 260 x 85 mm wheel is an inflatable wheel with a steel rim , providing better shock absorption and smoother trailer handling, especially on uneven surfaces. The air-filled tire effectively dampens vibrations and improves maneuverability. The steel rim reinforces the structure and increases resistance to loads and mechanical damage, ensuring durability in various conditions of use. An inflatable wheel differs from a solid rubber wheel in that it contains air, which allows it to better absorb shocks and uneven terrain. A solid rubber wheel is airless and therefore cannot be punctured, but it provides less vibration dampening.

Crank with thrust bearing

The crank is equipped with a thrust bearing , which significantly improves comfort. The bearing reduces friction during operation, resulting in smoother and lighter crank movement . This means that raising and lowering the jockey wheel requires less force and is more comfortable, even under heavy loads.

Anti-corrosion protection

The steel jockey wheel and cast iron clamp are electro-galvanized , ensuring high corrosion resistance and long service life even with intensive outdoor use. The zinc coating effectively protects the components from moisture, road salt , and changing weather conditions, increasing the durability and strength of the entire structure.
