Abstract

PURPOSE: To reduce the weight of the control section while avoiding the unbalance in weight of the entire hoist by making one power source common for the electromagnetic clutch and the elctromagnetic brake in a double speed electric hoist with fine speed operation.
CONSTITUTION: This hoist is equipped with a high speed motor HM, a low speed hoist motor LM, an excitation open electromagnetic clutch CL interposed between a drum selectively driven by the motors and first and second reduction mechanisms G1 and G2 and an electromagnetic brake BR which is actuated at the stoppage of the motors. A clutch coil CLC, a brake coil BRC, and a quick-break switch BrS are connected in series to each other and then, connected to a rectifier Re, while a short- circuit switch L adapted to be opened in the low speed operation is connected in parallel to the clutch coil CLC. With such an arrangement, one power source can be commonly used for the electromagnetic clutch CL and the electromagnetic clutch BR to accomplish the purpose.
