Abstract

Wear pads or bearings for telescoping crane booms consists of units on the rear and top and forward end and bottom of adjacent telescoping sections. Each wear pad unit comprises plural wear pad or plate sections floatingly mounted on cushioning elements within a retainer. The strength or spring constant of the cushioning elements may vary within the units to meet conditions of varying stress. The wear pad units are self-adjusting to accommodate inherent angularity between telescoping boom sections.
