Patent number: 6113130Abstract: The present invention is related to a transport trailer with a suspended articulated platform. The device comprises a platform (1) upon which is pivotally attached a cradle formed of two interdependent arms (6) of a shaft spanning the platform transversely near the longitudinal center of the platform. The fore arms (P'2) are pivotally connected at (P2-P'2). The top of each arm is linked to a fork made up of two tie-beams (2) and a T-shaped tow bar (3). These tie-beams are pivotally connected at (P3-P'3) and (P4-P'4). The hitch device (4) is linked to the hauling vehicle, which, in moving forward, exerts a force (F). This towing force results in the raising of the platform (1) so that it pivots around (P1-P'1) and (P2-P'2). This rotation takes place around the wheel shafts (5) so that they become locked in with the aid of the wedges (10). In the upright position, as shown, the tie-beams (2) are locked against the fore arms (6) at points (S) and (S').Type: GrantFiled: August 26, 1998Date of Patent: September 5, 2000Inventor: Roger Saulce

The dolly includes a pair of platforms and a wheel system having at least three castors extending downwardly from the platforms. The dolly is designed such that one step onto a latching or locking mechanism by the operator causes the wheel system to be forced downward relative to the stand thereby slightly lifting the power tool and stand off of the ground and enabling transport of same via the castors. Another step on the locking or latching mechanism disengages the wheel system and permits gravity to return the stand and tool firmly to the ground for use.Type: GrantFiled: May 22, 1998Date of Patent: June 27, 2000Assignee: Herculift Technologies, Inc.Inventors: Charles L. English, Jr., Douglas R. Stahl, William A. Hees

Patent number: 6062809Abstract: A passenger lift (10) is provided for loading a passenger (12) into and out of an aircraft (14). Lift (10) includes a chassis (38) having a front (34) end and a back (36) end. A plurality of wheels (62 and 63) are attached to the chassis (38) providing means for moving the lift (10). The lift (10) also includes an electrical energy source (70) for providing electrical energy, and an energy converter (104) for translating the electrical energy from the electrical energy source (70) to mechanical energy. The lift (10) includes a rear support (40) generally perpendicular to the chassis (38) and attached to the back end of the chassis (38). The lift (10) has a basket (48) for holding the passenger (12) while the passenger is raised and lowered with the lift (10) and (48) is located at the front end of the chassis (38). The lift (10) includes a pair of lift arms (44) for lifting the basket (48), and a pair of stabilizing arms (42) for providing stability to the basket (48).Type: GrantFiled: August 27, 1996Date of Patent: May 16, 2000Assignee: American Airlines IncorporatedInventors: Rex A.

Patent number: 6045317Abstract: A vehicle including an elevatable cargo box to facilitate cargo loading and unloading. The vehicle includes a U-shaped cargo area within which the cargo box is located by mounted guides. The cargo box is movable between elevated and lowered positions by cables, which is operated by a drive system and is laterally secured in the elevated position by cones being fully registered within blocks. In a preferred embodiment, the cargo box is retrofitted to an existing vehicle. A series of cables is connected to corners of the cargo box and a drive is operably connected to the series of cables for retracting and extending the cables effecting the movement of the cargo box.Type: GrantFiled: December 6, 1996Date of Patent: April 4, 2000Assignee: Tooling Technology Centre, Inc.Inventors: Paul Y. Boucher, Leslie T. Davey

Patent number: 6026341Abstract: The present invention is adapted to provide a method for identifying a machine dump occurrence of an earthmoving machine. The method includes determining an initial elevation of a point on the machine. The elevation of the point is then monitored to determine when a dumping threshold is exceeded. The ground speed is also monitored to determine if the machine 102 is moving at a speed indicative of dumping. When the machine speed is below a dumping speed, and the receiver 116 has exceeded a dumping threshold the machine 102 may be determined to have dumped its load.Type: GrantFiled: December 22, 1997Date of Patent: February 15, 2000Assignee: Caterpillar Inc.Inventor: Gregory R. Harrod

Patent number: 6024528Abstract: Stretcher supporting and lifting apparatus normally stowed beneath the body of an ambulance has a frame in the form of a plurality of telescoping members fastened to and extendable lengthwise relative to the chassis of the vehicle and carries a lifting device on which a platform is mounted. The frame may be extended and tilted downwardly from a stowed position to the ground with the platform in its lowest position. The platform has guide tracks for the wheels of a transportable stretcher and the stretcher may be rolled onto the tracks and a patient supporting litter lowered onto the platform. The lifting device is then actuated to lift the platform and the stretcher to the desired height so that the wheels may roll onto the floor of the ambulance. After the stretcher has been moved thereon, the lifting device is lowered to lower the platform, and the frame may be tilted back to the horizontal position and retracted to its stowed position beneath the ambulance.Type: GrantFiled: September 18, 1998Date of Patent: February 15, 2000Inventor: William L. Taylor

Patent number: 6019565Abstract: An apparatus is provided for the longitudinally aligned lifting and manipulation of bulk material containers having apertured or tapered bases, or horizontally oriented ribs, or external peripheral lips on the sides thereof. The apparatus comprises a central frame having a pair of fork like elongate legs extending therefrom, and supporting wheels located at the central frame and at the distal ends of the legs. The legs are spaced sufficiently to straddle the base and simultaneously engage both sides of a container to be lifted, and lifting action achieved by a plurality of power rams which either extend the wheels more downwardly so that the legs and frame of the device are lifted with respect to the ground in con junction with tongues adapted to engage lifting apertures of the container, or by the upward extension of link bars which engage the side walls of a container so that the container is lifted with respect to the legs and frame of the device.Type: GrantFiled: November 12, 1996Date of Patent: February 1, 2000Inventor: Thomas Gesuale

Patent number: 6010296Abstract: A seat stowage cart enables loading, transporting, and stowing a removable vehicle seat of the type found in sport utility vehicles. The seat is drawn manually upon a pair of ramps which pivot on a frame. The seat passes over the pivot axis, urging the ramps toward a seat stowage position, therein supported by a pair of support members. The ramps are adjustable for seats of varying width. The frame is selectively variable in height, and includes wheels. A pawl is provided for releasably locking the ramps against pivoting, and for blocking the seat wheels from rolling.Type: GrantFiled: December 2, 1997Date of Patent: January 4, 2000Inventor: Bruce G. Enders
