Abstract
A modular lift system may include, but is not limited to: one or more lift segments each including: a lift-truss structure; and a drive shaft having at least one end-coupler, at least one lift assembly coupled to the lift-truss structure, and at least one drive segment including: a drive-truss structure; a drive motor coupled to the drive-truss structure; and a drive-coupler attached to the drive motor and configured to engage the end-coupler of the drive shaft.
Claims5
A modular lift system comprising:
- at least one lift segment including:
- a lift-truss structure;
- a drive shaft;
- at least one lift assembly coupled to the lift-truss structure, the at least one lift assembly including:
- a lift drum operably coupled to and configured to co-rotate with the drive shaft;
- and
- a lift line configured to wrap around the lift drum as it co-rotates with the drive shaft,
- at least one corner lift segment including:
- a corner truss structure;
- a corner drive shaft;
- at least one corner lift assembly coupled to the corner truss structure, the at least one corner lift assembly including:
- a corner lift drum operably coupled to and configured to co-rotate with the corner drive shaft;
- and
- a corner lift line configured to wrap around the corner lift drum,
- one or more bracket portions operably couplable to the at least one lift segment and at least one corner lift segment and configured to retain the at least one lift segment and at least one corner lift segment at an angle relative to one another;
- and
- a flexible connector operably coupling the drive shaft of the at least one lift segment to the corner drive shaft of the at least one corner lift segment.

A modular lift system comprising:
- a first lift segment including:
- a lift-truss structure;
- a drive shaft;
- at least one lift assembly coupled to the lift-truss structure:
- a first power transfer unit operably coupled to the drive shaft of the first lift segment;
- a second lift segment including:
- a lift-truss structure;
- a drive shaft;
- at least one lift assembly coupled to the lift-truss structure,
- a second power transfer unit operably coupled to the drive shaft of the second lift segment;
- and
- at least one belt configured to frictionally engage a drum of the both the first power transfer unit and the second power transfer unit such that rotation of the drive shaft of the first lift segment induces co-rotation of the drive shaft of the second lift segment.
