A construction vehicle includes a telescoping boom assembly that includes a first section and at least a second section configured to nest within and to extend from the first section. At least one wear pad is positioned between the first section and the second section. The wear pad includes a length, a first surface, and a second surface spaced apart a height from the first surface. A first portion of the wear pad includes a first bending stiffness. The wear pad also includes a second portion having a second bending stiffness, wherein the second bending stiffness is different than the first bending stiffness. Optionally, the height of the wear pad between the first surface and the second surface is substantially the same in the first portion and the second portion. Optionally, the construction vehicle is a crane.

A beam for use in construction equipment is made from tailor welded panels. At least one of the panels is made from at least two pieces of material such as steel welded together with the weld running the length of the beam. The weld between pieces of steel can either be parallel to the longitudinal axis of the beam, or the pieces can be tapered and the weld will be at an angle diverging from the longitudinal axis of the beam. The two pieces of material have a different compressive strength per unit of length in a direction transverse to the longitudinal axis of the beam. In some embodiments a top panel is welded to two side panels to form two top corners of the beam and a bottom panel is welded to the two side panels to form two bottom corners of the beam.
