A track beam includes a main component and a guide component. The main component includes a top plate, a bottom plate, and a web plate. The bottom plate is disposed below the top plate, and the web plate is connected between the top plate and the bottom plate. The guide component includes a guide plate and a connecting structure. The guide plate is disposed between the top plate and the bottom plate. The guide plate includes a planar plate structure extending in a longitudinal direction and is spaced apart from the web plate in a transverse direction. The connecting structure is connected between the main component and the guide plate such that the guide plate is connected to the main component through the connecting structure.

A transfer device may include a transfer part including transfer rails installed on a ceiling of a manufacturing line for an integrated circuit device and a transfer vehicle running along the transfer rails, and a safety fence disposed adjacent to the transfer part. The safety fence may include a plurality of first horizontal supporting portions disposed in parallel to the transfer rails, a plurality of second horizontal supporting portions connecting the plurality of first horizontal supporting portions to the transfer rails, a plurality of vertical supporting portions extended from the plurality of horizontal supporting portions, respectively, and a plate portion connected to the plurality of vertical supporting portions. The safety fence may be partially foldable and partially unfoldable.

The present invention relates to the field of automated transportation systems. Particularly, it relates to a transportation system comprising guide-ways or tracks, vehicle units [100, 100a] with wheel-axle assembly for switching of vehicles from primary [20] to secondary track [22] on changing trajectory to maintain same vertical plane and the method. It comprises of central controller [101], vehicle chassis with main wheels [2W], guide wheels [4iw, 4ow], guide blocks [05, 06], actuator [09]. The chassis [30] has set of contractible axles fixed to wheels [2W] to enables movement from primary [20] to secondary track [22] by withdrawing the wheels [2W] from expanded position [C] to contracted position [C] or vice-versa. The forces required to compress the spring loaded axle axis is derived from inner guide wheels rolling over the edge flange [26] when swung using single linear motor actuator [09] and related electronic controls.

A personnel platform facilitates maintenance on a loop sorter of a material handling system in a distribution center. The personnel platform includes wheeled axle assemblies, having left and right wheel hub assemblies connected by a lateral support structure, engaged for longitudinal travel to opposing wheel channels of a section bed of the loop sorter that guide a train of material handling carriages. The personnel platform also includes a carrier platform comprising multiple sub-platforms, such that each sub-platform is pivotally attached to an adjacent sub-platform. Further, the personnel platform includes a rail assembly having upright structures and side rail assemblies attached between an adjacent pair of upright structures. Further, the side rail assemblies extend and retract according to changing spacing between the adjacent upright structures as the personnel platform moves along a curved section.

An inspection system for inspecting the track of an amusement ride with at least one rail. A vehicle is provided that is designed to ride along the track. The vehicle supports cameras. The cameras are positioned in unobstructed areas. The cameras image the rail from different angles as the vehicle rides along the track. The images recorded by the cameras are reviewed to identify any defect or issue with the rail or its supporting framework that may impact from the safety of the ride.

A system of solar panels over a water reservoir may include a plurality of piers secured to a floor of the water reservoir and extending from the floor to a fixed elevation above a maximum water elevation of the water reservoir. The system of solar panels may also include at least one support structure on the plurality of piers. The system of solar panels may also include a plurality of solar panels supported by the support structure over at least a portion of the water reservoir. The plurality of solar panels both reduce evaporation from the water reservoir and generate solar electricity.
