ABSTRACT:
A detachable main frame for an exercise machine includes a casing containing a support column of the exercise machine therein and having a closed side, an open side, and a cover removably attached to the open side of the casing and having a configuration conforming to that of the open side of the casing. In such a manner, the cover can be removed from the casing so as to expose the open side of the casing, thereby allowing a tool to be inserted into the casing of the main frame to facilitate maintenance inside the casing.
