A device for transporting loads suspended on raised tracks over a ground surface includes a container of materials to be transported, a structure supporting the container, and a movement mechanism for moving along the tracks, having a first motorised wheel and a second motorised wheel, independent of one another and activatable about axes of rotation coaxial with and perpendicular to the two longitudinal sides of the supporting structure. The transport device has a stabilizer with at least a first idle rolling element and at least a second idle rolling element coupled to the supporting structure so as to be arranged on opposite sides with respect to the coaxial axes of rotation of the first motorised wheel and the second motorised wheel, so as to be pivoting about axes parallel to the two longitudinal sides of the supporting structure and the tracks.

An automated storage and retrieval system includes a track system including a first set of tracks arranged in a horizontal plane and extending in a first direction, and a second set of tracks arranged in the horizontal plane and extending in a second direction that is orthogonal to the first direction. The first set of tracks and the second set of tracks form a grid pattern in the horizontal plane including a plurality of adjacent grid cells. Each grid cell includes an opening defined by the first set of tracks and the second set of tracks such that the track system includes a plurality of openings. A plurality of storage containers are arranged in columns beneath the track system such that the storage containers are located vertically below the openings. A plurality of container handling vehicles for lifting and moving the storage containers are configured to move on the track system and access the storage containers via the openings. Each container handling vehicle of the container handling vehicles includes a lower part in contact with the track system and an upper part. The lower part has a width and a length that form a vehicle footprint. The vehicle footprint of the lower part has dimensions smaller than the opening such that a contact area of the container handling vehicle does not extend into an adjacent grid cell. The upper part, which is disposed vertically above the lower part, includes a protruding section and a recessed section. The protruding section is configured to extend beyond the lower part into the adjacent grid cell. The recessed section is of a complimentary shape to the protruding section such that the recessed section is configured to receive other protruding sections of other vehicles of the container handling vehicles. The lower part further includes a storage space configured to accommodate a storage container of the storage containers.

An improved border barrier system is disclosed. The system includes columns situated periodically along an international border, beams extending horizontally between tops of the columns, metallic based walls extending between each pair of columns, a power line extending within the beams, a continuous electric railway located on top of the horizontal surface, electric rail cars powered by the electric railway, sensor arrays located periodically along the border barrier system, stations located periodically along the border barrier system, each station including a housing structure configured for housing personnel, a power generating station or power relay station coupled to the power line and the electric railway for powering the electric railway, and a tunnel that allows the electric railway to enter one end of the housing structure and exit another end of the housing structure.

A track system on which a skater dolly can roll, comprising one or more pairs of rails and one or more rail clamps. Each rail clamp supports one or two pairs of rails. Rails held side-by-side are parallel to each other. Rail clamps can also secure two rails in end-to-end configuration. The distance between rails can be about 5/16 of an inch. The track system can include a skater dolly, the load-bearing wheels of which are angled 20-30 degrees away from vertical to provide clearance past the rail clamps. The skater also has stabilizing wheels that are approximately perpendicular to the load-bearing wheels, and which secure the skater to the rails when the skater is in a non-upright e.g. upside-down orientation. The system can include a motor pulley system that moves the skater along the rails.

An embodiment of a transport system may include a vehicle and a circuit with a rail extending at least on sections of the circuit. The system may include a drive system configured for a positive drive for propelling the vehicle along the circuit, wherein, at least on sections extending along the circuit, the drive system has first and second engagement members. The first engagement member may have a first projection and an adjacent second projection on at least sections of the circuit and, between the first and adjacent second projections, grooves, which are each bounded by the first and adjacent second projections. The first engagement member may have one or more openings, of which at least one through-opening is formed between the first and adjacent second projections. Through the through-opening may engage a connecting member configured for connecting the first engagement member with the rail for attachment to the rail.
