ABSTRACT:
An apparatus to remove rubber from airplane tires from an airport runway surface. There is a manifold arm which rotates at as high as two thousand five hundred rpms over the runway surface, with a plurality of water jets being discharged downwardly at a relatively high pressure (e.g. thirty five thousand P.S.I.) against the runway surface. Even though the water pressure as at a level several times higher than that at which damage to the runway surface can occur, at the relatively high linear speed of the water jets (e.g. ninety to one hundred eighty miles per hour), there is no noticeable damage to the runway surface, but yet there is quite effective removal of the accumulated rubber. Also disclosed is a particular shaft and seal assembly which is capable of operating at relatively high rotational speeds and delivering the high pressure to the manifold arm.
