System, method and apparatus for servicing a pulverizer

A method for servicing a pulverizer having a housing, a journal assembly pivotally connected to the housing, a grinding mechanism operatively connected to the journal assembly, a journal opening within the housing adjacent to the journal assembly that provides an access point to an interior of the housing, and a plurality of holes in the housing surrounding the opening, the method comprising the steps of:

• mounting a hoist apparatus to the housing of the pulverizer adjacent to the journal opening in the housing, the hoist apparatus including:
• a frame assembly received about the journal opening within the housing of the pulverizer, the frame assembly including a back plate with a plurality of apertures configured to receive fasteners for mounting the frame assembly to the plurality of holes in the housing of the pulverizer, formed from a pair of spaced apart, opposed leg members, and a cross member extending between the leg members to connect a top end of each of the leg members with one another to provide the frame assembly with dimensions that correspond to a size of the journal opening within the housing, a top plate extending outwardly from the cross member of the back plate away from the housing of the pulverizer, and a plurality of support plates coupled to the back plate and the top plate, each of the support plates extending between the back plate and the top plate at a downward angle between the leg members to support the top plate from below;
• a sheave assembly including a plurality of sheaves supported by the frame assembly, the sheaves being mounted for rotation about respective horizontal axes;
• a motor operatively connected to one of the plurality of sheaves;
• and
• a cable received by the sheave assembly;
• extending the cable from a sheave of the sheave assembly in the hoist apparatus through the journal opening into the housing of the pulverizer;
• connecting the cable to a component within the housing;
• actuating the motor of the hoist apparatus to rotate the sheave to withdraw the cable;
• and
• rotating the component out of the housing through the opening.
