ABSTRACT:
An overhead travelling carriage is provided wherein three drums are arranged on a base of a hoist unit along the sides of an imaginary equilateral triangle. Two motors and a brake are arranged along imaginary lines which join the imaginary center of the imaginary equilateral triangle where a hypoid gear of the hoist unit is positioned and the imaginary apices of the imaginary equilateral triangle. The rotation of the hypoid gear is transmitted to a spur gear on the drum side of the spur gear in order to drive the drum. As a result, the hoist unit of the overhead travelling carriage may be reduced in size.
