Definitions

  • the present invention relates to a lifting and turning apparatus for use in handling payloads or materials which are too heavy to be manually manipulated or are not so manipulated to avoid repetitive strain injury (RSI).
  • Bulk materials whether provided in containers from which the material is dispensed or reels from which a length of cable or sheet material may be unfurled, often require special handling or orientation to allow the material to be used or loaded.
  • the apparatus of the invention may be adapted for the most convenient uses and the terms "materials” and “reels” as used herein are not intended to be restrictive or to limit the scope of the disclosure. It will be appreciated by the skilled reader that any suitable payload may be manipulated by the apparatus and that the shape of the payload is not confined to reels or substantially cylindrical shapes.
  • the invention relates particularly to the lifting and turning of material reels such as paper and polyethylene reels.
  • the invention is directed to overcoming some of the established disadvantages associated with payload manipulation, particularly manipulation apparatus using combined electric and pneumatic or hydraulic systems.

  • a simple hoist arrangement comprises a lifting motor which raises and lowers the payload under direct control of an operator.
  • the hoist is operated by a pushbutton, pendulum type controller.
  • Hoists which include a means for rotating or otherwise manipulating a payload are traditionally cumbersome, complex and require a reasonable amount of operator skill.
  • the present invention provides a lifting and turning apparatus adapted for connection to and defining a point of connection to an overhead support, the apparatus comprising a payload engaging means which is operably coupled to and supported by at least one cable means being acted upon by first and second electrically actuable brake/drive units, the centre of gravity of the lifting and turning apparatus, with or without the payload, being maintained substantially in line with the point of connection to the overhead support.
  • the apparatus includes a hoist incorporating a driven cable engaging means to -3- effect turning of the payload engaged.
  • the in-line centre of gravity allows a lighter or lower rated apparatus to be used for existing payloads or facilitates the manipulation of heavier payloads than heretofore.

  • the payload engaging means comprises a chuck adapted to engage a corresponding receiver within a payload for securing the payload during the manipulation thereof.
  • the invention also provides a pendulum controller comprising a housing which presents to an operator switches to enable and disable a lifting and lowering function and control means for directional control of the payload turning and said lifting and lowering function.
  • a pendulum controller comprising a housing which presents to an operator switches to enable and disable a lifting and lowering function and control means for directional control of the payload turning and said lifting and lowering function.
  • the controls are presented in a readily understandable format to facilitate differing levels of operator skill and experience.
  • a processing means is provided in the controller so that manipulation of payloads may be automated. Preset parameters relating to the position and orientation of the payload engaging means and/or the payload are programmable into said processing means.
  • the automated control of the manipulation of the payload may be realised by transferring a control programme to the processing means via an electrical interface or via a keyboard on the controller.
  • electric motors can be used to realise a hoist with improved payload characteristics.
  • the advantages inherent in decreased weight of the apparatus and the improved features of handling and manipulating payloads arise from the combination of the invention.
  • the resultant apparatus is simple to use and has better handling characteristics with basic ON/OFF control of the brake/drive units and hoist. It will be appreciated the proportional control and other control algorithms may be applied to the apparatus of the invention, however, in is basic form, the performance of the lifting and turning apparatus is equal to, if not superior to, prior art devices of significantly greater complexity.
  • operably as used herein is intended to include chains, ropes, straps and other material webs capable of supporting the weight of the payload or being rated according to the Safe Working Load of the hoist or apparatus in its entirety.

  • Operator controls for the brake/drive units 5,6 are housed in a pendulum housing having a pair of ON/OFF switches and a pair of PUSH ON/RELEASE OFF buttons to enable the drive and brake modes.
  • FIG. 1 Under operator control, the hoist 2 is moved along the beam B until the reel chuck 14 is brought into line with the reel core C. The chuck 14 is locked into the core C and the operator engages the lifting drive mode of the second brake/drive unit 6 to elevate the reel R sufficiently to clear the stack from which the reel has been taken.
  • the apparatus with reel may be moved along the length of the beam B at will, as shown in Figure 2, when the operator has locked the brakes (enabled the brake mode) of each brake/drive unit 5,6.
  • the operator selects one brake/drive unit 5,6, in this case the second brake/drive unit 6, and engages the lifting drive mode while maintaining the brake mode of the first brake/drive unit 5.
  • the centre of gravity is maintained in line with the point of connection with the overhead support beam B via the hoist 2 and wheel unit 3, as will be appreciated from Figure 3.
  • the reel has been turned through 90° so that it may be lowered in this position to a surface such as the floor or mounted on a horizontally disposed reel spindle (not shown).
  • the brake mode is engaged on the second brake/drive unit 6 and disengaged on the first unit 5.
  • the operator then presses the actuator button on the controller to allow the reel to be lowered.
  • the reel chuck is disengaged from the reel core C and the apparatus 1 is withdrawn in this position, as illustrated in Figure 4b.
  • Figure 5a and 5b show the coilspring drive 15 of the brake/drive units 5,6.
  • the coilspring drive is coupled to the driven sprocket for engaging the chain 10.
  • a brake mechanism 17 is connected via a shaft by a gear train 19 which, when engaged by the brake mechanism, prevents rotation of the driven sprocket.
  • the operator is presented with a pair of ON/OFF switches for the lifting/lowering function and for the turning function.
  • a pair of PUSH BUTTON switches is provided to effect the direction of the lifting/lowering and turning functions. For example, for lifting the reel, the lifting switch is enabled and the turning switch is disabled. The two push buttons are then pressed in unison to lift the reel.
