とを特徴とするホイストの非常上限回路。 A contact point for switching forward/reverse of the hoisting motor controlled via a push button switch block is connected between the power supply and the hoisting motor, and power is supplied to the hoisting motor when the hoist's load block rises above a certain value. In the case where an emergency upper limit switch is provided for disconnecting, a main contact of a remote control breaker is arranged between the power supply and the hoisting motor, and a return switch is connected to the on-excitation side terminal of the coil that controls this main contact. The emergency upper limit circuit for a hoist is characterized in that the switch is connected and housed in the push button switch block, and an emergency upper limit switch with a normally open contact is provided at the off-excitation side terminal of the remote control breaker.
