In some embodiments, a mobile safety platform includes a protective enclosure coupled to a frame of a wheeled transport. The wheeled transport is configured to raise the protective enclosure so that the wheeled transport can relocate the protective enclosure and to lower the protective enclosure so that the protective enclosure and/or deck is deployed on a substrate. In at least one embodiment, the wheeled transport is configured to raise and to lower the protective enclosure utilizing a lifting and lowering mechanism, such as a hydraulic system. In at least one embodiment, the lifting and lowering mechanism is configured, when deployed, to transfer at least some of the weight of the transport to the protective enclosure and/or deck. In at least one embodiment, the wheeled transport comprises a trailer. In other embodiments, the wheeled transport can be a motor vehicle including an engine.

A side structure of a bus includes a skirt rail. Window fillers are connected to the skirt rail at lower ends, extend in an upper side, and are arranged from a front to a rear with a predetermined interval. A waist rail extends from the front to the rear with a predetermined distance in the upper side of the skirt rail and is engaged with each of the window fillers. A first region includes a first member connecting the waist rail and the skirt rail and a second member connecting the upper part of the first member and the lower end of the window filler. A second region includes a third member connecting the waist rail and the skirt rail and a fourth member connecting the upper of the third member and the lower part of the window filler.

A vehicle lowering system having a cargo surface with an adjacent pivoting arm is connected to a vehicle at a pivot point. The pivoting arm moves between a raised and a lowered position by an actuator that is affixed to a frame and the pivoting arm. The frame has an upper portion and a lower portion that provides structure for the portion of the frame that is beyond the pivot point and actuator. The pivot arm has a spindle that holds and allows a wheel to rotate. The spindle has an axis that is always located above the cargo surface. The actuator is movable between an extended position and a retracted position. When the actuator moves between the extended and retracted position, the pivoting arm moves the vehicle between a raised and a lowered position.

A suspension assembly for a vehicle modified to transport an individual using a wheelchair. The modified vehicle includes a lowered floor having an inclined portion to accommodate a ramp. The suspension replaces a portion of the suspension of an original equipment manufactured vehicle to accommodate the lowered floor, which is lowered from the original floor and which includes a width not found in the original floor. The suspension assembly includes a left bushing arm and a right bushing arm operatively connected together by a front and a rear crossmembers. Vehicle frame mounts, coil spring locations, and shock absorber locations are maintained, while accommodating the depth and width of the lowered floor. The additional weight of the vehicle, due to the addition of the lowered floor and anticipated weight of wheelchaired individuals, is accommodated by the suspension to maintain rider comfort.

Embodiments of the Working Chute are comprised of A working livestock chute comprised of an adjustable width alleyway from 18 inches wide to 36 inches wide; one or more double hinges; one or more catwalks; one or more pins; a plurality of chains; a stabilizer bar; support straps; one or more palpation gate assemblies; a hydraulic gooseneck; a hydraulic gooseneck lifting means; an underslung torsion tube; and a plurality of free floating gates.

Provided are a transportation device for transporting heavy plate-shaped cargoes such as thick plate products, and a transportation system using the transportation device. The transportation device may include: a device body unit; a device moving unit provided on the device body unit to move the transportation device; and a cargo loading unit provided on the device body unit for self-loading cargo. The transportation device is capable of rapidly loading and transporting plate-shaped heavy objects such as thick plate products of an iron mill without using additional lifting/unloading apparatuses and heavy pallets (cassettes) for markedly decreasing the total transportation (distribution) time necessary for lifting, transportation, and unloading of cargo, providing efficient transportation environments, improving productivity, and decreasing costs.

A vehicle lowering system is provided having a movable arm that is connected to a vehicle through an upper link and a lower link. The upper and lower links pivot with respect to the vehicle on pivot points on one end and pivot with respect to the arm on pivot points at the opposite end. The spacing of the pivot points and the length of the upper and lower arm create an instant center, about which the movable arm pivots. An actuator is connected to the vehicle on one end and the movable part of the suspension on the opposite end. The actuator is movable between an extended and a retracted position. When the actuator moves between the extended and retracted position, the movable arm moves the vehicle between a raised and a lowered position.

A bed height adjustment system for adjusting height of a bed of a vehicle including an air spring supporting the bed; a valve unit connected to an air tank and configured to adjust height of the air spring by supplying and discharging air; and a vehicle-control ECU provided with a dump-signal line and a return-signal line each connected to the valve unit. The valve unit adjusts the height of the air spring into a dump mode by inputting a signal of the dump-signal line, returns the height of the air spring into a normal mode by inputting a signal of the return-signal line, and maintains the dump mode or the normal mode when the signal is not input.

A bed height adjustment system for adjusting height of a bed of a vehicle includes: an air spring supporting the bed; a valve unit connected to an air tank and configured to adjust height of the air spring by supplying and discharging air; a relay provided with a dump-signal line and a return-signal line each connected to the valve unit; a pressure switch configured to be switched between an ON state and an OFF state based on whether air is supplied from the valve unit; and an indicator that becomes illuminated state when powered when the pressure switch is in the ON state and becomes non-illuminated state when the pressure switch is in the OFF state.

A modular low-floor transport system comprises at least one drive module and at least one carrier module. The drive module includes a drive base and a drive chassis connected to the drive base. The drive chassis includes at least one driven wheel coupled to a drive. The carrier module includes a carrier base and a carrier chassis connected to the carrier base. The carrier chassis includes at least one non-driven carrier wheel. The drive base and the carrier base are rigidly connected to each other with respect to a stroke direction, and the drive chassis is movably mounted in the stroke direction to the drive base.
