Abstract: A foldable roll-over protection structure is provided for use on a vehicle movable in a generally fore-and-aft direction. The foldable roll-over protection structure includes a frame comprising a base section and an upper section. The base section is connectable to the vehicle. The upper section is swingable relative to the base section between a forward position in which the upper section projects forwardly from the base section, a rearward position in which the upper section projects rearwardly from the base section, and an upright position positioned between the forward and rearward positions. A hinge assembly swingably interconnects the sections of the frame. The hinge assembly is configured to releasably secure the upper section in each of the positions of the upper section.

Abstract: A folding roll-over protective structure has hinges that may be attached weld-free to the folding legs of the structure. Selectively removable locking pins may be used to lock the structure in its fully upright use position or a collapsed folded position. Strategically located cushions within the hinges take up slack in the system to minimize rattling when the structure is locked in its use position.

Abstract: A bending machine is provided to form a multiplicity of predetermined types of bends within several planes in elongated, heavy gauge workpieces of various sizes and shapes by pressure between a stack of dies and a pair of swingable anvil plates carried by elongated wings each of which is, in turn, swingable to adjust the distance between the anvils. Slide rails for the workpiece are readily accessible for loading and unloading. The die stack includes releasable vise-like clamps which grip the workpiece to preclude distortion during bending, and the stack can be raised or lowered to provide proper alignment of preselected die units of the stack.
