Inverted carrier lift device system and method

A method for manipulating the position of a workpiece in a workstation, the method comprising:

• transferring a trolley engaged with a conveyor along a path of travel to a predetermined position at a workstation, the trolley connected to a carrier having a workpiece support beam operable to support a workpiece;
• connecting a tether to the workpiece support beam;
• engaging the tether with a rotatable drum mounted to the trolley;
• engaging a motor stationarily mounted in the workstation with a ratchet coupler connected to the drum when the carrier is positioned at the predetermined position at the workstation;
• energizing and selectively rotating the motor engaged with the ratchet coupler to selectively rotate the drum to unspool a length of the tether from the drum lowering the workpiece support beam relative to the trolley by a lifting mechanism from a raised position to a lowered position along a carrier axis of travel in the workstation;
• conducting a process on the workpiece;
• energizing and selectively rotating the motor engaged with the ratchet coupler to selectively rotate the drum to spool the length of the tether onto the drum raising the workpiece support beam from the lowered position to the raised position in the workstation by the lifting mechanism;
• and
• transferring the trolley from the predetermined position at the workstation by the conveyor along the path of travel.

A method for manipulating the position of a workpiece in a workstation, the method comprising:

• transferring a trolley engaged with a conveyor along a path of travel to a predetermined position at a workstation, the trolley connected to a carrier comprising one of a scissors device or a telescopic post device connected trolley and having a workpiece support beam operable to support a workpiece;
• disengaging a locking mechanism from one of a foot connected to the workpiece support beam or the telescopic post device permitting the lowering of the carrier from a raised position to the lowered position;
• lowering the carrier relative to the trolley by a lifting mechanism from the raised position to the lowered position along a carrier axis of travel in the workstation thereby extending respective one of the scissors device or the telescopic post device;
• conducting a process on the workpiece;
• raising the carrier from the lowered position to the raised position in the workstation by the lifting mechanism thereby contracting respective one of the scissors device or the telescopic post device;
• and
• transferring the trolley from the predetermined position at the workstation by the conveyor along the path of travel.

A method for manipulating the position of a workpiece in a workstation, the method comprising:

• transferring a trolley engaged with a conveyor along a path of travel to a predetermined position at a workstation, the trolley connected to a carrier having a workpiece support beam operable to support a workpiece, the carrier further comprising a workpiece engaging device connected to the workpiece support beam operable to selectively engage the workpiece;
• lowering the carrier relative to the trolley by a lifting mechanism from a raised position to a lowered position along a carrier axis of travel in the workstation;
• one of disengaging or engaging the workpiece by the workpiece engaging device while the workpiece support beam is positioned at the lowered position in the workstation;
• conducting a process on the workpiece;
• raising the carrier from the lowered position to the raised position in the workstation by the lifting mechanism;
• and
• transferring the trolley from the predetermined position at the workstation by the conveyor along the path of travel.

A method for manipulating the position of a workpiece in a workstation, the method comprising:

• transferring a trolley engaged with a conveyor along a path of travel to a predetermined position at a workstation, the trolley connected to a carrier comprising a workpiece support beam operable to support a workpiece, the carrier further comprising a pair of telescopic post devices positioned apart along the workpiece support beam, each telescopic post device connected to the trolley and the workpiece support beam;
• lowering the carrier relative to the trolley by a lifting mechanism from a raised position to a lowered position along a carrier axis of travel in the workstation thereby extending the telescopic post device;
• conducting a process on the workpiece;
• raising the carrier from the lowered position to the raised position in the workstation by the lifting mechanism thereby contracting the telescopic post device;
• and
• transferring the trolley from the predetermined position at the workstation by the conveyor along the path of travel.
