Abstract
There is disclosed a pendant control arrangement for overhead electric hoists featuring a helically wound elastically memorized insulative cord enclosing a plurality of electrical conductors for attachments at their opposite ends to terminals in the hoist motor and in the pendant control switches. This coiled cord encloses a straight line strain relief cable or the like which is of a length equal to the anticipated length required to support the pendant switch control panel at proper elevation below the electric hoist, and simply mechanically connects at its opposite ends to said motor and said control panel. Thus, changes in the distance required between the hoist motor and the control panel are more readily accommodated by reason of the mechanical connections of the relief cable, while leaving the electrical connections of the control cord conductors undisturbed.
