An unmanned rail vehicle for surveillance, inspection, and/or maintenance of an industrial site is provided. The rail vehicle includes at least two carry rollers adapted for engaging on an upper rail side of a rail, wherein the center of gravity of the rail vehicle is vertically below the upper rail side; and at least one support roller connected to the chassis and adapted for rolling against a lateral rail side of the rail to laterally displace the center of gravity of the rail vehicle with respect to the upper rail side.

An overhead conveyor for conveying heavy loads such as lorry frame components, lorry trailers or the like, the overhead conveyor having passive travelling mechanisms guided on rails for receiving the heavy load, wherein at least two passive travelling mechanisms are connected via a load-bearing crossmember to form a passive carrier, and the load-bearing crossmember is designed to receive the heavy load, extends substantially along the conveying direction, and is mounted underneath the passive travelling mechanism, and at least one stationary drive device for introducing a driving force into the passive carrier, wherein the drive device has a friction wheel-counter wheel arrangement and a contact device, the friction wheel being mounted on one side of the load-bearing crossmember in order to transmit the driving force to the load-bearing crossmember, and the counter wheel being mounted, transverse to the conveying direction, on the side of the load-bearing crossmember opposite said first side in order to transmit a transverse force to the load-bearing crossmember and/or to absorb a transverse force from the load-bearing crossmember, wherein a contact force is exerted by means of the contact device via the counter wheel and/or via the friction wheel in the direction of the load-bearing crossmember. The drive device has a preloading device designed to apply an additional preloading force to the contact device.

A conveyor system comprising a fixed, non-powered rail defining a conveyor path and an automated conveyor carrier (ACC) supported on the rail to be movable along the conveyor path. The ACC includes an on-board motor and an on-board electrical power source selectively powering the on-board motor to drive the ACC along the rail. The ACC may include a wireless sleep mode module operable to selectively shut off power to an on-board ACC controller.

The Curtis Protocol, an aircraft control interface, is provided. The Curtis Protocol standardizes the division and selection of aircraft flight regimes and flight modes within the selected flight regime.

The present invention relates to the field of coal mine underground auxiliary transportation equipment, and particularly relates to an overhead monorail driving unit group realizing mechanical fast power distribution. The overhead monorail driving unit group realizing mechanical fast power distribution includes a rail, wherein the rail is connected with driving portions, carrying trolleys and a hoisting beam, the hoisting beam is disposed in a middle position of the driving portions and the carrying trolleys, and the driving portions, the carrying trolleys and the hoisting beam are connected through driving portion short pull rods, frame-shaped pull rods and driving portion long pull rods. Overhead monorail driving portions have four paths for transmitting a driving force to the hoisting beam, the frame-shaped pull rods directly transmit the driving force of the driving portions in positions far away from the hoisting beam to the hoisting beam, the objective is to reduce an accumulated peak value of the driving force of the driving portion in a mode of serial-parallel arrangement of the overhead monorail driving portions, the problem of horizontal direction bending failure of the rail caused by the driving portions in an operation process of an overhead monorail is solved, and the reliability and adaptability of overhead monorail transportation equipment are improved.

The present invention provides a dual rail track system for independently moveable carts in an industrial control environment in which upper and lower rails of a track are substantially L shaped to allow upper and lower groups of rollers of a cart to orthogonally contact the upper and lower rails, respectively, to provide vertical and horizontal control of the cart while in motion along the track. The shape of the rails and arrangement of the rollers, orthogonal with respect to the rails in vertical and horizontal planes, provides an efficient support system allowing high speed movement of carts, including through turns, with only two rails and with symmetric weight distribution of the cart. Flexible members provided with respect to each roller also provide resiliency to allow the rollers to adapt to variations in the track.
