Abstract

The lower wear pads of multi-section telescoping crane booms comprise assemblies located on the forward end and bottom of each boom section. Each such assembly consists of a support housing for a pair of laterally spaced wear pad units and within the support housing are retainer means for each wear pad unit. Each unit includes low friction wear pad elements for direct frictional engagement with the bottom face of the next innermost boom section and spherically curved universally self-adjusting seating means for the wear pad elements.
