An early warning system for a tractor operator engaged in towing or pushing an aircraft includes two ultrasonic sensors that are used to create a detection area in which the aircraft should be present when the steering angle is well within a safe range. When one of the detectors fails to detect the presence of the aircraft, then the operator is alerted, before over steering can occur, in order that corrective action can be undertaken. Accordingly, complex distance-measuring algorithms can be avoided as can the requirement that an aircraft fuselage have a specially modified detection region.

A method and an apparatus for automatically removing pieces of luggage that have different surface properties and dimensions and getting the pieces of luggage ready for further transport by means of a gripper that is hingedly connected to a robot arm is described. The method includes: a) moving the gripper and the container that is to be emptied close together; b) determining the first piece of luggage to be removed; (c) gripping the piece of luggage using a horizontal suction elements (3) and withdrawing the luggage horizontally; d) if the vertical suction elements (4) are not yet able to sufficiently grip the luggage, the vertical suction elements (4) are repositioned and turned off, the vertical suction elements (5) are repositioned, and then turned on to re-grip the piece of luggage.

A wheel pulling apparatus and method for removing vehicle wheels by pushing against the mounting studs of a motor vehicle wheel assembly. The invention is designed to remove or break uni-mount wheels from large wheel assemblies. A push plate is positioned onto the wheel by at least one receiver. At least two threaded grappling hooks are affixed to the wheel, and the threaded portion of the grappling hooks are slid through slots in the push plate. Washers are inserted and nuts are tightened onto the threaded portion. The nuts are then alternately tightened causing the push plate to snug onto mounting studs and to pull the wheel from the wheel assembly.

An aircraft handler (10) for use with an undercarriage of an aircraft, the handler being self-propelled and comprising a generally “U” shaped body (11) having arms (12 &13) linked by a bridge (14) at one end thereof with a pair of drive wheels (16 &17) located one at the free end of each arm, with at least one wheel(15) located adjacent the bridge(14). A pair of clamping jaws (51) are mounted on the body (11) between the drive wheels (16 &17) and the bridge (14)and jaws (51) have a lower profile than the arms (12 &17). The drive wheel (16 &17) are driven by DC electric motors powered by batteries stored in the arms.

A dolly is particularly adapted to lift, support and maneuver a four-wheel vehicle. The dolly comprises an adjustable, generally U-shaped frame assembly for each vehicle tire. The frame assembly has pairs of reciprocally opposed first and second frame members adapted to be positioned adjacent opposite sides of a tire and to lift the vehicle by way of the tires. A castering wheel assembly supports the vehicle on a ground surface. The frame assembly is pivotably mounted on a tractor.

A wheel dolly is disclosed that is suited to serve as both an automobile jack, capable of holding large loads aloft for extended periods, relying on only mechanical systems and eliminating hydraulic systems. In a further aspect, the wheel dolly of the present invention does not include extended arms, handles, or levers for pumping or rotating the lifting mechanisms. Each lifting element terminates in only a single nut exposed to the user. Preferably, each nut of each lifting system has the same plan dimensions as the other, thus providing the advantage of allowing the user to operate the dolly with a driver and only one socket.

A factory layout including a track circuit, one or more wheeled carts for traversing the track circuit and a tire/wheel assembly carried by the wheeled cart. One or more work stations can be positioned at locations along the track circuit. Various wheeled cart embodiments are disclosed and various work station configurations are disclosed.

A guard device for a handrail in an entry zone of an escalator is disclosed, which assures safety of an entry of the escalator, sanitary maintenance of the handrail by sterilization, efficient advertisement of products and business corporations, and clean maintenance of air in the entry of the escalator. The guard device includes a guide channel at its bottom to receive a part of the handrail. The guard device further includes a sterilization unit to sterilize the handrail, an advertising display provided on a front face thereof, and an air-cleaning unit provided at a side wall thereof.

A wheel lift system for efficiently lifting and positioning a wheel and tire onto a wheel hub. The wheel lift system includes a first arm and a second arm pivotally attached to one another, a plurality of caster wheels attached to the lower portion of the arms, and a first support and a second support extending from the arms respectively for supporting a wheel and tire. A bias member is preferably attached to the arms for providing a bias force that assists in elevating the wheel and tire.

A self-propelled transport aid for wheeled structures is advantageously provided. The transport aid generally includes a chassis, a lift assembly operatively supported thereby, and preferably a wheel capturing apparatus operatively united with the lift assembly. The wheel capturing apparatus has a first configuration for receipt of a wheel upon a wheel landing of the apparatus, and a second configuration for retention of the wheel received upon the wheel landing in the first configuration, wherein the first configuration of the wheel capturing apparatus is associated with a down position thereof. Alternate means for receiving and retaining a portion of a wheeled structure are further disclosed.

A dual mode end effector is disclosed. The dual mode end effector includes a bridge member having a first end and a second end, wherein the bridge member includes a first substantially axial flange extending from the first and, wherein the bridge member includes a second substantially axial flange extending from the second end; a tire/wheel gripping assembly connected to the bridge member, wherein the tire/wheel gripping assembly includes a pair of substantially axial members, a substantially radial support member, and a pair of radially-projecting engaging assemblies, wherein the pair of substantially axial members are movably-supported upon the substantially radial support member, wherein a first end of the substantially radial support member is connected to the first substantially axial flange of the bridge member, wherein the a second end of the substantially radial support member is connected to the second substantially axial flange of the bridge member, wherein a first radially-projecting engaging assembly of the pair of radially-projecting engaging assemblies is connected to an inner radial surface of a first substantially axial member of the pair of substantially axial members, wherein a second radially-projecting engaging assembly of the pair of radially-projecting engaging assemblies is connected to an inner radial surface of a second substantially axial member of the pair of substantially axial members.
