Abstract: A gate may include a first supporting arm and an adjustable arm. The first supporting arm may include an interior surface and an interior cavity. The adjustable arm may include an insertable end, an adjustable compression member and a compression fitting. The insertable end may be configured to be inserted into the interior cavity of the first supporting arm. The adjustable compression member may be disposed at the insertable end. The compressing fitting may be configured to adjust the adjustable compression member. When the insertable end is inserted into the interior cavity of the first supporting arm, the adjustable compression member is adjusted to compress against the interior surface so that the adjustable arm is fixed relative to the first supporting arm.

Abstract: A gangway comprises at least one component formed from a continuous piece of metal. The at least one component formed from the continuous piece of metal may be a support structure or an underbody, a platform, a ramp, a step, or other support surface. A method for manufacturing such a gangway comprises forming the at least one component from the continuous piece of metal.

Abstract: A handrail or a swing gate for fall restraint equipment comprising an outer rail constructed from a single, continuous piece of tubular metal, a midrail constructed from a single, continuous piece of tubular metal, and a toeboard constructed from a single, continuous piece of sheet metal, where the outer rail is constructed to receive portions of the midrail and toeboard for an integral construction.

Abstract: Uprights and lateral or connecting posts to be used in conjunction with a gangway or other fall restraint equipment where the uprights and posts are created by cutting portions of integral, continuous pieces of tubular metal rather than welding smaller pieces of stock material together. Sidepost assemblies or handrails are created by connecting the uprights and posts together.

Abstract: An articulating cage configured to raise and lower with respect to a fixed structure. The articulating cage comprises support structures affixed to the fixed structure and that include one or more springs.
