Abstract
An elongated pipe conduit snow making tower, and assembly method, having an upper end spray nozzle head and pivotally supported on a support pipe for vertical inclination by a hydraulic ram jack enabling infinite non-preselected incremental inclinations. A ram safety latch automatically latch/catches the tower pipe if the jack leaks. Secondary and tertiary external flexible water hoses are selectable to feed associated spray head snowmaking nozzles, and an internal compressed air conduit feeds spray head seeding nozzles. Secondary and tertiary ball valve assemblies mounted on a water feed block are outlet coupled to their respective hoses. In drain condition turbulent primary water continually washes against a valve ball flow closure side for an anti-freezing effect. The spray head is a four-piece modular planar stack up of disks each carrying spray nozzles that all discharge forwardly away from the pipe tower in generally parallel spray patterns.
