Castor OF EXTRA LONG SPRING GATE WITH A DIAMETER OF 100 MM LOAD 60KG TO 130KG WITH A TRAVEL OF 200MM

REF: 99314

Castor designed to relieve the hinges of very heavy swinging gates. The strong travel of the spring allows this model to be installed on steep terrain. Indeed, the spring at rest measures 360mm, at maximum the spring will compress by 160mm, which leaves a maximum travel of 200mm.

In order to know precisely the effort required to assist your gate, you can use a basic dynamometer found online to attach to the bottom of your gate and measure the force needed to make it level.

The steel used to manufacture the plate and the fork is 6mm thick, making it practically indestructible for most gates. We have applied black paint to the castor, but it should be kept in mind that during the raising/lowering of the rod, it will inevitably rub against the plate, which will cause some paint to come off; ideally, regularly adding grease to the rod will help reduce friction.

The stated load corresponds to the maximum compression of the spring, as the wheel can withstand 180 kilograms and the metal frame over 300 kilograms.

The compression spring has spaces between the coils when it is not loaded. The distance between the coils decreases when the spring is loaded and compressed. In principle, a compression spring should never be compressed to the point where the coils touch each other. Its lifespan would be significantly shortened. The ideal solution is to use 60% of the maximum force and maximum travel. A compression spring should never serve as a physical stop.
