The ordinary electric hoist brake is implemented by a motor. Remove the tail cover, and then remove the four screws of the fixed adjustment nut. Finally, use a wrench to adjust the nut clockwise to the extreme position, and then reverse Rotate the clockwise hand once, and finally install the fastening screw, even if the adjustment is successful.

On the one hand, because the axis of the motor is an electric hoist perpendicular to the axis of the drum, generally a worm gear is used directly, so the size of the width is large, and the structure is also bulky, which results in low mechanical efficiency and difficult processing. There is no manufacturer. Production of this type of structure.

The electric hoist with the motor axis parallel to the drum axis generally has the advantages of small height and length. Disadvantages are the large width, complicated grouping, and complicated manufacturing and assembly. The turning radius of the track is large.

The electric hoist with the motor installed in the drum has the advantages of small length and compact structure. Its main disadvantages are poor motor heat dissipation conditions, poor grouping, inconvenient inspection, installation, and maintenance of the motor, and complicated power supply devices.

The electric hoist with the motor installed outside the drum has the advantages of good grouping, high degree of generalization, easy lifting height change, and convenient installation and maintenance. The disadvantage is that the length is large.
