Abstract: A compact, trailing, auxiliary axle system is attached to a truck for carrying additional weight and distributing the weight of the truck over a greater number of axles and a greater maximum total distance of distribution of those axles. The apparatus is attached high, and may be secured to the body of a truck, such as a refuse truck, reducing the total length of extension from the rear of the truck, yet pivoting from a comparatively high position for easy stowage above the bubble or bulkhead protruding from the tailgate of a truck. Hydraulic actuation relies on pulling, during deployment, providing improved resistance to buckling, protection from road damage, with short coupling for improved strength of booms, hydraulics, and cross members. Conduits may carry control and power through the frame of the assembly, and conventional suspension components may be used.

Abstract: A one way clutch is rotatable with a member (e.g. helical spring) and a sleeve while the spring is being constrained by the manual winding of a cable on the sleeve. The sleeve is constructed to wind the cable uniformly on the sleeve. During the constraint imposition, the clutch drives a shaft and a disc. One disc surface abuts bearing liners affixed to a casing. The other disc surface is separated from the spring. Calibrated numbers are printed on the casing periphery. A dial externally supported by, the casing is rotatable relative to the casing to any of the calibrated numbers to adjust the friction force between the liners and the disc when the disc is rotated. The casing is vented at its opposite ends. When the spring is being constrained or the constraint is being released, air flows through the vents and through the space between the successive turns in the spring and past the disc to cool the disc.
