KNOTT TK57 swivel support wheel with handle 500kg 57mm

KNOTT TK57 swivel support wheel with handle 500kg 57mm

The TK57 swivel support wheel from KNOTT is equipped with a tube with a diameter of 57 mm and a total length of 710 mm including the wheel , which ensures a solid, stable structure and comfortable operation even with a higher drawbar.

The product features a factory-welded mounting bracket with a 140x112 mm hole spacing and an 11 mm diameter. This solution eliminates the need for an additional clamp, simplifies installation, and increases the durability of the entire connection.

Permissible load

The permissible load when parked is up to 500 kg , which is a very high value and allows for exceptionally stable and safe support of the trailer during loading, unloading, and extended periods of standstill. This high load capacity ensures reliable support for the drawbar, minimizes the risk of tilt, and increases comfort around the trailer even with a heavier load. Maintaining the maximum load parameters is crucial to maintaining the durability of the mechanism, protecting structural components from overload, and ensuring long and trouble-free product operation.

Extension length

The jockey wheel extension is 300 mm , providing an appropriate range of drawbar height adjustment. This extension allows for convenient adjustment of the trailer to various ground conditions and facilitates connecting and disconnecting it from the towbar. The appropriate extension range increases comfort and stability when parked.

Type of wheel

The 210 x 75 mm wheel is made of durable plastic , ensuring low weight and resistance to moisture and corrosion. This design is suitable for everyday use, enabling smooth maneuvering of the trailer on hard surfaces such as asphalt, paving stones, or concrete. The plastic wheel requires no pumping, is puncture-resistant , and does not deform in contact with moisture, ensuring trouble-free operation and a long service life.

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 jockey wheel is made of hot-dip galvanized steel, providing high-quality protection against corrosion and guaranteeing long service life even with intensive outdoor use. A thick layer of zinc effectively protects the steel components from moisture, road salt, and changing weather conditions, increasing the durability and resistance of the structure to damage.
