The main frame—comprising the upper, middle, and bottom frames—forms the core component of the gyratory crusher. Among these, the upper frame plays a critical role in stabilizing the main shaft, transferring power, and absorbing heavy impact loads. Long-term heavy impact, vibration and dust erosion inevitably cause frame deformation, sealing failure and metal fatigue, making upper frame replacement one of the most essential overhaul works for gyratory crushers.
This article focuses on the upper frame’s structure, core functions, daily maintenance, and the complete standardized replacement procedure for field operators.
