Definitions

  • the present invention relates generally to vehicles for handling heavy loads, and more particularly, to an improved vehicle incorporating a mechanism for lifting, supporting, and transporting coils.
  • conventional coil carriers In order to prevent tipping, conventional coil carriers typically employ a relatively long wheelbase and substantial dead vehicle weight to counterbalance the load. As a result, conventional coil carriers require substantial room to maneuver into position to engage, lift, and stack coils. Rows or stacks of coils must be spaced apart a sufficient distance to provide an aisle of a width which permits such extensive maneuvering of the carrier into appropriate contact with the coils .
  • a related object is to facilitate a relatively dense pack of coil stacks to minimize storage space and costs associated therewith.
  • An additional object is to provide a vehicle which may be readily maneuvered by an operator.
  • a further object is to provide a vehicle that may be used to lift objects either to the side or to the front of the vehicle and which may be used to move the load over a broad range of motion.
  • the present invention provides a load handling vehicle having a mainframe supported on a plurality of wheels and a lift apparatus which is rotatably coupled to the mainframe by a turntable.
  • the turntable supports a counterweight and the lift apparatus which may be used to engage and lift a load, such as a coil.
  • a load such as a coil.
  • the lift apparatus can lift and engage a load disposed forward the vehicle when the lift apparatus is in a position substantially parallel to the mainframe, or a load disposed alongside the vehicle when the lift apparatus is positioned substantially perpendicular to the mainframe.
  • the lift apparatus is coupled to upright supports secured to the turntable and includes a pair of lift arms pivotally coupled to the upright supports at one end and to a mast and engagement probe at the opposite end.
  • Movement of the lift arms and, accordingly, the mast and engagement probe in a vertical plane is provided by means of a pair of hydraulic lifting cylinders coupled to the lift arms, respectively.
  • the tilt angle of the mast is controlled by a second pair of hydraulic cylinders pivotally coupled to the upper end of the mast at one end and to the upright support on the turntable at the other end.
  • the engagement probe is retractably mounted in the mast by a rack and pinion gear controlled by a hydraulic motor.
  • the engagement probe may be fully retracted within the mast and the mast positioned within the footprint of the wheelbase of the vehicle.
  • the vehicle may be advanced in an aisle between two stacks of coils with the turntable rotated such that the mast disposed to the side or front of the vehicle, while maintaining the mast and engagement probe within the footprint of the vehicle.
  • the mast may then be raised to an appropriate level adjacent the coil, the engagement probe advanced to engage the coil, the coil lifted, and the turntable rotated, if desired, to move the mast and coil to an alternate position for transportation.
  • the vehicle offers versatility in handling coils, and may be effectively utilized in an area requiring a minimal amount of floor space beyond the footprint of the wheelbase.
  • the coils may be stacked in relatively close rows, minimizing the floor space required for storage or more efficiently utilizing the floor space available, and, accordingly, minimizing storage costs .
  • FIGURE 1 is a side elevational view of a load handling vehicle constructed in accordance with teachings of the invention showing the lift apparatus in the lowered position in solid lines and in the raised position in phantom lines.
