Liftarms / Triangles

A liftarm is a highly modified 1 x n Lego plate, 1/2 the thickness of a Lego brick, with connector holes and a flanged cross hole at one end. A cross axle placed through the flanged end, when rotated, would cause the arm to lift. More recent examples have been further modified to include connectors or decorative elements. A triangle is the canonical name for the triangular shaped liftarm.
