Abstract
A system is useful for positioning a load, such as a test head. The system includes an arm which supports the load and which moves along a first vertical axis. The system also includes a rotation unit for rotating the first vertical axis about a second vertical axis spaced apart from the first vertical axis.
Claims40
A system for positioning a load, said load coupled to a cable, said system comprising:
- a column which defines a first vertical axis;
- an arm unit which supports said load and which moves a) along said first vertical axis, and b) along and relative to said column;
- a rotation unit for rotating said column about a second vertical axis spaced apart from the first vertical axis;
- said column positionable so that it is closer to said load than said second vertical axis is to said load;
- said load positionable by said arm unit so that said cable intersects said second vertical axis and said cable is situated to a side of said column.
A system for positioning a load, said load coupled to a cable, said system comprising:
- a column which defines a first vertical axis;
- an arm unit which moves a) along said first vertical axis and b) along and relative to said column and which supports said load;
- a cable support which moves along a third vertical axis independently of said arm unit and which supports said cable coupled to said load;
- and
- said load positionable by said arm unit so that said cable is situated to a side of said column.
A system for positioning a load, comprising:
- an arm unit which supports said load and which moves along a vertical column which defines a first vertical axis,
- a rotation member for rotating said first vertical axis about a second vertical axis spaced apart from said first vertical axis;
- a cable support which moves along a third vertical axis and which supports a cable coupled to said load;
- and
- a further rotation member which provides rotation of said load about a horizontal axis, wherein vertical motion of said cable is preventable while said load is rotating about said horizontal axis.
A system for positioning a load, said load coupled to a cable, said system comprising:
- a column which defines a first vertical axis;
- an arm unit which supports said load and which moves a) along said first vertical axis, and b) along and relative to said column;
- a rotation unit for rotating said column about a second vertical axis spaced apart from the first vertical axis;
- said second vertical axis situated not more than three widths of said cable away from said test cabinet;
- said load positionable by said arm unit so that said cable intersects said second vertical axis and said cable is situated to a side of said column.
A system for positioning a load, said load coupled to a cable, said system comprising:
- a column which defines a first vertical axis;
- an arm unit which supports said load and which moves along said first vertical axis;
- a rotation unit for rotating said first vertical axis about a second vertical axis spaced apart from the first vertical axis;
- said cable situated along an axis which intersects a center of gravity of said load;
- said load positionable by said arm unit so that said cable intersects said second vertical axis and said cable is situated to a side of said column.
