A loose wheel restraint safety system provides bolt-on support brackets in a system for attachment to the chassis or to the body of a vehicle, to which brackets wheel restraint bars are detachably mounted. The brackets of the system are located adjacent the wheels of the vehicle, such that the restraint bars, when mounted, are located in close proximity to the tires and extend horizontally across the wheel. The system elements, when bolted in place form, in combination with the adjoining vehicle bed or chassis portions, substantial wheel enclosures that permit each wheel and rim to turn freely upon its axle or spindle, while restraining the wheel against lateral deviation from its axle. The system is applied to each outer wheel of a multi-wheel rig, to restrain a break-away wheel against run-away, such that the driver, upon observing the situation, can pull the rig off the road and to a halt. The noise of such a containment occurring is anticipated to serve as adequate warning to the driver, to enable his early response. The brackets and restraint bars are robustly constructed of simple, high strength elements. The support brackets are sized to lie within the plan profile of the vehicle, such that local ordinances governing vehicle width are not infringed by the presence of the brackets. The restraint bars, when secured in place may exceed such ordinances. The restraint bars are readily removed when travelling through such jurisdictions, and to provide access to, and for servicing the tires and wheels.
A loose wheel restraint safety system in combination with a wheeled vehicle having a plurality of wheels rotatable mounted upon axle means attached to the vehicle, said system comprising first support brackets attached to the vehicle within the plan profile of the vehicle and adjacent said wheels, wheel restraint bars having carrying handle means, said restraint bars being detachably secured by removable pin means to the first brackets, in use to extend substantially horizontally, in close proximity to the tires of the wheel, said first brackets and said restraint bars, in association with adjoining portions of said vehicle providing wheel enclosures wherein said wheels are free to rotate in unrestricted fashion upon said axle means, and whereby, in use, upon the loosening of a wheel upon a said axle means, the respective adjacent one of said restraint bars restrains said wheel against substantial lateral deviation from said axle means, said restraint bars having inwardly inclined fender portions at their ends, to safeguard the ends of said bars against impact.
