PROBLEM TO BE SOLVED: To provide a lift assembly drum that can wind and unwind cables in a smooth and controlled manner so as to minimize friction and noise.SOLUTION: A lift assembly system 10 and method can include: a beam clamp tube receiver adapted to allow a tube 11 to slide relative to a beam and be secured to the beam; a cable keeper and a slack line detector adapted to maintain cables 31 in position about a drum immediately after loss of cable tension; a horizontally oriented low profile cable adjuster adapted to adjust the length of a cable; an overspeed braking mechanism; a fleet pivot arm pivotable on the end of the tube 11 so as to guide the cables 31 along a desired fleet angle; and a pull-type load sensor connected between a tube and a drum adapted to sense changes in a load force and adjust movement of a load. |
