Hoisting mechanism

摘要

The present invention relates to hoisting mechanisms and can be utilized to utmost effectiveness in electric hoists. The hoisting mechanism is provided with a rope drum enclosed within a casing and a driving unit of which the motor is accommodated within the rope drum and operatively connected with a reducing gear and a brake. The housing of the motor on the brake side is arranged in supports permitting angular displacement of the output shaft of the driving unit relative to the axis of symmetry of the mechanism and adapted to transmit to the reaction torque to the casing. The drum has one end thereof mounted in a support, the other end of the drum having a flange pivotally supported by the output shaft of the reducing gear of which the input shaft is axially aligned with the output shaft. The disclosed construction enhances reliability and durability of the hoist, facilitates its assembling, operating and maintenance and improves the ergonomic characteristics of the mechanism.
