Hoist assist mechanism which assists in the manual movement of a coil insertion tool assembly to and from an operational position. The hoist assist mechanism has a rotatable base, to which is attached an upwardly extending post. At the upper portion of the post is a sheave. Also, attached to the base, adjacent the post, is a support arm which supports a coil insertion tool assembly. The support arm is pivotally attached to the rotatable base. A cable is attached to the arm. The cable extends over the sheave and is also attached to a spring which assists in pivotal movement of the arm. The spring is adjacent the post or enclosed by the post. Preferably, plurality of posts and arms are pivotally attached to the base. Each pivotal arm supports a coil insertion tool assembly. Thus, coil insertion tool assemblies for different stator cores can be easily and readily moved into and out of operational position as desired.
