Abstract
A jib crane that includes an open column having a first end and a second end opposite to the first end that is adapted to operably engage with a ground surface. The jib crane also includes at least one interior space collectively defined by the open column between the first end and the second end. The jib crane also includes a crane beam operably engaged with the open column at the second end of the open column. The jib crane also includes a bearing assembly operably engaged with the crane beam and the open column, and the bearing assembly has at least one bearing positioned inside of the at least one interior space defined by the open column.
Claims23
A jib crane, comprising:
- an open column having a first end and a second end opposite to the first end, wherein the second end is adapted to directly attach to a ground surface;
- at least one interior space collectively defined by the open column between the first end and the second end;
- a crane beam operably engaged with the open column at the first end of the open column;
- a bearing assembly operably engaged with the crane beam and the open column, the bearing assembly comprises a tube having a first end that operably engages with the crane beam and a second end opposite to the first end, at least one bearing positioned inside of the at least one interior space defined by the open column and operably engages with the tube and the open column, and a mounting plate directly attached to the first end of the tube;
- and
- a trolley assembly operably engaged with the crane beam and the bearing assembly and directly attached to the mounting plate.

A method of moving an object with a jib crane between a first position and a second position, comprising steps of:
- engaging a bearing assembly of the jib crane with an open column of the jib crane, wherein the bearing assembly includes a tube having a first end that operably engages with a crane beam of the jib crane and a second end opposite to the first end, at least one bearing positioned inside of the open column and operably engages with the tube and the open column, and a mounting plate directly attached to the first end of the tube;
- engaging a trolley assembly to the crane beam and the bearing assembly and being directly attached to the mounting plate;
- attaching the object, via a hanger assembly, with the jib crane;
- and
- moving the object with the jib crane between the first position and the second position.
