Abstract
A wear pad for a telescoping boom assembly includes a wear pad body having a first surface and a second surface oppositely positioned from the first surface and spaced from the first surface by a height of the wear pad body, a groove formed in one of the first surface and the second surface, the groove extending along a length of the wear pad body, and an insert positioned in the groove such that a portion of the insert projects outwardly from the groove. The telescoping boom assembly includes an inner boom section and an immediately adjacent outer boom section. The wear pad is configured to be installed between the inner and outer boom sections.

A wear pad for a telescoping boom assembly comprising:
- a wear pad body having a first surface and a second surface oppositely positioned from the first surface and spaced from the first surface by a height of the wear pad body;
- a plurality of recesses formed in at least one of the first surface and the second surface and extending in a width direction of the wear pad body, the recesses spaced apart along a length of the wear pad body;
- a groove formed in one of the first surface and the second surface, the groove extending along the length of the wear pad body, wherein the groove includes an open side elongated along the length of the wear pad body;
- and
- an insert positioned in the groove such that a portion of the insert projects outwardly from the open side of the groove,
- wherein the wear pad is configured to be installed between an inner telescoping boom section and an immediately adjacent outer telescoping boom section.
A telescoping boom assembly, comprising:
- an outer boom section;
- an inner boom section disposed in the outer boom section and configured for telescoping movement to extend out of and retract into the outer boom section;
- a wear pad having a first surface and a second surface oppositely positioned from the first surface and spaced from the first surface by a height of the wear pad;
- a plurality of recesses formed in at least one of the first surface and the second surface and extending in a width direction of the wear pad, the recesses spaced apart along a length of the wear pad;
- a groove formed in one of the first surface and the second surface, the groove extending along the length of the wear pad;
- and
- an insert positioned in the groove, the insert having a portion which projects outwardly from the open side of the groove,
- wherein the wear pad is installed at one of the inner boom section and the outer boom section and the insert is configured to contact the other of the inner boom section and the outer boom section.
A telescoping boom assembly of a crane, comprising:
- an outer boom section;
- an inner boom section disposed in the outer boom section and configured for telescoping movement to extend out of and retract into the outer boom section;
- a first wear pad having a first surface and a second surface oppositely positioned from the first surface and spaced from the first surface by a height of the first wear pad;
- a plurality of recesses formed in at least one of the first surface and the second surface and extending in a width direction of the first wear pad, the recesses spaced apart along a length of the first wear pad;
- a groove formed in one of the first surface and the second surface, the groove extending along the length of the first wear pad, the groove having a depth and an open side elongated along the length of the first wear pad;
- an insert positioned in the groove, the insert having a height greater than the depth of the groove such that a portion of the insert projects outwardly from the open side of the groove;
- and
- a second wear pad,
- wherein the first wear pad is installed at a rear portion of the inner boom section and is configured to move with the inner boom section relative to the outer boom section, and the second wear pad is installed at a forward portion of the outer boom section and is fixed relative to the outer boom section.
