System Facilitates Changing Crusher Head Nuts by Hand

Technofast Industries developed the EziTite Hydraulic HeadNut system to facilitate changing out head nuts on gyratory crushers. The system features a reusable hydraulic clamping nut, which uses a hand pump to develop the precise tensile load required, integrated mechanical locking screws and a protective wear cover. The assembly is screwed by hand onto the crusher shaft (replacing the original nut) until the base is tight. Hydraulic pressure is then applied. The locking screws are then engaged and the wear cover bolted in place. When it is time to remove the HeadNut, the installation procedure is simply reversed and the nut is removed by hand. The system eliminates the need for use of flogging spanners, sledge hammers, and cutting torches.
