Claims

[Scope of utility model registration request]

In an electric lifting device comprising a rope hoisting drum driven by a motor fixed in a main body case and an elevating body that goes up and down via a lifting rope, the electric lifting device is arranged on a side of the main body case facing the hoisting drum. The lifting rope is wound around a pair of first and second pulleys provided, and extends in a direction perpendicular to the lifting rope between the first and second pulleys, and one end thereof is connected to the rope. a tensioning fitting slidably engaged with the tensioning fitting and having the other end fixed to the biasing spring means; and a rope slack detection switch means actuated by movement of the tensioning fitting in the orthogonal direction. Lifting device.
