Also mounted on the mounting surface are a detent mechanism, a locking mechanism, and a clamping mechanism. The detent mechanism includes a roller that is spring biased against the turntable, and that is operable to resist rotation of the turntable at preselected angular positions. The locking mechanism includes a lever, a locking member, and a biasing member. The locking member engages notches in the turntable to prevent the turntable from rotating. The lever actuates the locking member and the biasing member biases the locking member toward the notches for engagement therewith. The clamping mechanism includes at least one clamp that is adapted to engage a portion of an apparatus.Type: GrantFiled: July 21, 1998Date of Patent: September 5, 2000Assignee: Harley-Davidson Motor CompanyInventor: Michael L.

Patent number: 6089354Abstract: A forklift with four wheels mounted on a chassis and a gantry which carries the forks and can be folded down longitudinally for transporting the forklift. The chassis of the forklift consists of two parts joined together by a hinge. The two chassis parts pivot relative to each other about a horizontal transverse axis and about a vertical axis, allowing for concurrent movement in the perpendicular axes of the chassis.Type: GrantFiled: December 18, 1997Date of Patent: July 18, 2000Assignee: Palfinger Crayler Staplertechnik GmbHInventor: Franz Hettegger

Patent number: 6044932Abstract: A device for and method of ergonomically removing parts from a parts bin, so that an operator does not have to unnecessarily bend to remove parts, using an open-ended bin, a platform removably contained within the bin, and a mechanism for lifting the platform which is, also, removably contained within the bin. The mechanism for lifting the platform may be a manually operated or automatically operated scissor-type jack, hydraulic cylinder, or pneumatic cylinder. Also, the platform may be vertically adjusted by a spring whose spring constant is chosen to correspond to the weight of the parts within the bin.Type: GrantFiled: June 14, 1999Date of Patent: April 4, 2000Assignee: Ergonomics SpecialistsInventors: Matthew Zane Neal, Dennis Richard Weber

Patent number: 6035972Abstract: A portable lift table is described having a wheeled frame, a table with a workpiece support surface, and elevating means for selectively raising and lowering the table. The workpiece support surface may be positioned at two different heights relative to the elevating means. The table can be raised to a height greater than that of the mast of the apparatus. The lift table is useful for carrying a workpiece from the floor to a workbench or from low bench (or grinder) to workstation height. The table also preferably includes a roll gate to prevent objects from rolling off the end of the table.Type: GrantFiled: April 6, 1998Date of Patent: March 14, 2000Inventor: John M. Beattie

Patent number: 5941347Abstract: A portable lift for transporting cargo between different vertical levels of a building. The lift comprises a frame mounted for movement on a plurality of wheels. A carriage having a cantilevered platform that is adapted to support the cargo is mounted for vertical movement on the frame between a lower level and an upper level. The wheels can be manually moved between a lower supporting position where they support the frame for movement to an upper, non-supporting position. Movement of the wheels to the upper, non-supporting position automatically engages a locking mechanism to lock the frame to the building to prevent accidental movement of the frame during a loading operation. The platform of the carriage can be selectively positioned at either a lower position to receive cargo from mechanical handling equipment, or at an upper position to receive a manually carried cargo.Type: GrantFiled: May 27, 1997Date of Patent: August 24, 1999Assignee: Pflow Industries Inc.Inventors: Robert H. Pfleger, Gene M. Barth

Patent number: 5931262Abstract: A cargo delivery vehicle is described having storage for multiple tiers, or levels, of cargo. The delivery vehicle includes two or more interior elevating platforms, at least one on either side of a center structural wall running parallel to the side walls. Substantially continuous side access doors provide total exterior access to the lowermost tier of cargo. Cargo stored at the upper tier may be positioned by an elevating means at the level of the lower tier for either rear loading or side retrieval purposes. The center structural wall supports a transverse roof truss system that carries suspended outboard loads inward to the center wall. This non-traditional framing system greatly reduces the structural requirements of the side walls and floor, thereby permitting largely open framing for multiple side access ports as well as a minimized floor thickness to permit easier access from the pavement.Type: GrantFiled: January 16, 1996Date of Patent: August 3, 1999Inventors: Robert J. Greenlaw, Todd M. Greenlaw

Patent number: 5885048Abstract: A powered cart for moving heavy objects. The cart has a container portion that is elevated and lowered under power with a floor of the container portion capable of being lowered onto a surface supporting the cart. The floor has an inclined edge that provides a ramp for loading items onto the cart. The cart is propelled by a steerable wheel and the wheel is provided with a braking system. A removable gate is provided for securing the open side of the chassis and is provided with an automatic latch mechanism that locks the gate in position when the container portion is elevated off the supporting surface.Type: GrantFiled: October 8, 1997Date of Patent: March 23, 1999Inventor: James Kenneth Barth

Patent number: 5870824Abstract: A jet aircraft engine transport apparatus utilizes three major subcomponents. The first subcomponent is a shipping stand which enables a jet aircraft engine to be configured for transport in either a truck transport mode or air transport mode. The second subcomponent is a fan dolly which releasably secures the fan section of the jet aircraft engine for transport. The fan dolly serves the dual purpose of enabling removal of the fan section from the jet aircraft engine and providing a means of transport so that the fan section may be transported on the fan dolly or loaded onto a fan shipping frame, the third major subcomponent of the transport apparatus of this invention. The fan shipping frame enables transport of the fan section in either an upright or horizontal position, and further provides for a fan storage container for securing the fan blades of the fan section.Type: GrantFiled: June 23, 1997Date of Patent: February 16, 1999Assignee: Stanley Aviation CorporationInventors: Gerald D.
