An apparatus to facilitate the replacement of a grinding wheel secured to a mounting plate. The apparatus includes a frame having two spaced-apart uprights. An elongated support bar extends between and is pivotally mounted to the uprights while a mounting plate of a grinding wheel is detachably secured to the support bar. A lift table is mounted to the frame between the uprights and movable between a raised position in which the lift table is positioned adjacent the support bar and a lowered position in which the lift table is spaced downwardly from the support bar. The lift table is dimensioned to support a grinding wheel. An actuator is mounted to the frame and selectively moves the lift table between its raised and lowered positions.
