A variable speed hoist comprising a rotary switch that changes the rotational speed in multiple stages, the rotary switch being mounted on a push lead operation box. (2) The variable speed hoisting machine according to claim 1, characterized in that a plurality of rotary switches are arranged. The brief description of the drawing has been amended as follows. "Front view of the push button operation box" on page 9, line 4 of the specification is corrected to "diagram of its operating characteristics."

Claims

[Claims for Utility Model Registration] (1) In a hoisting machine whose driving source is a motor controlled by an inverter, the motor is rotated by controlling the inverter and changing its outlet in multiple stages. A variable speed hoist is equipped with a rotary switch that changes the speed in multiple steps, and the rotary switch is mounted on a push button operation box. (2) The variable speed hoisting machine according to claim 1, characterized in that a plurality of rotary switches are arranged.
