A tower lift comprising:
- a rail module extending in a vertical direction;
- a plurality of carriage modules configured to be movable along the rail module, each carriage module having a carriage configured to carry an object;
- and
- an interference avoidance module configured to avoid travel interference between the plurality of carriage modules traveling opposite directions along the rail module,
- wherein the rail module includes:
- a frame extending in the vertical direction;
- and
- a linear motor coil installed on the frame,
- wherein each of the plurality of carriage modules includes a linear motor magnet coupled with the carriage and configured to interact with the linear motor coil to move the carriage in the vertical direction,
- wherein the linear motor coil includes a plurality of linear motor coils installed on the frame so as to be spaced apart from each other along the vertical direction,
- wherein each of the plurality of linear motor coils includes a pair of linear motor coils spaced apart from each other, and
- wherein a part of the linear motor magnet, when viewed in a plan view, is inserted into a space between the pair of linear motor coils.
