2. Lifting beam - Wikipedia

   en.wikipedia.org/wiki/Lifting_beam

   The lifting beam (also known as traverse, spreader beam) is a steel beam that is attached to the hook of the crane in order to spread the slings from one end of an elongated load (like a wall panel) to another. The bottom of the beam has multiple connection points for hanging the load. [1] H-shaped traverse. The lifting beams are used in ...

3. Rigging (material handling) - Wikipedia

   en.wikipedia.org/wiki/Rigging_(material_handling)

   Rigging is the equipment such as wire rope, turnbuckles, clevis, jacks used with cranes and other lifting equipment [1] in material handling and structure relocation. Rigging systems commonly include shackles, master links and slings, and lifting bags in underwater lifting.

4. Airy points - Wikipedia

   en.wikipedia.org/wiki/Airy_points

   A beam supported at its Airy points has parallel ends. Vertical and angular deflection of a beam supported at its Airy points. Supporting a uniform beam at the Airy points produces zero angular deflection of the ends. [2] [3] The Airy points are symmetrically arranged around the centre of the length standard and are separated by a distance equal to

5. Jack (device) - Wikipedia

   en.wikipedia.org/wiki/Jack_(device)

   The farm jack also known as a railroad jack, high lift jack, handyman jack, trail jack or kanga-jack was invented in 1905. It consists of a steel beam with a series of equally spaced holes along its length, and a hand-operated mechanism which can be moved from one end of the beam to the other through the use of a pair of climbing pins.

6. Vibratory stress relief - Wikipedia

   en.wikipedia.org/wiki/Vibratory_stress_relief

   After stress relief treatment, the braces (rust-colored, structural beams), which are used to maintain the desired shape during welding, were removed. The spacing between the two "arms" remained the same; no change was detectable (measured to 1/32" or less than 1 mm), and the spacing remained so throughout assembly, testing (to 60 ton test ...

7. Cantilever - Wikipedia

   en.wikipedia.org/wiki/Cantilever

   In the cantilever wing, one or more strong beams, called spars, run along the span of the wing. The end fixed rigidly to the central fuselage is known as the root and the far end as the tip. In flight, the wings generate lift and the spars carry this load through to the fuselage.
