Wearpad arrangement

A boom assembly comprising:

• a first boom member;
• a second boom member that is slidable relative to the first boom member in a first direction;
• a stop member attached to the first boom member, the stop member at least partially defining a receptacle that faces the second boom member when the second boom member is positioned on the first boom member;
• a closure member that is attachable to the first boom member in a fixed position proximate the stop member and movable away from the fixed position;
• and
• a planar wearpad that is insertable into the receptacle in the first direction when the closure member is moved away from the fixed position and the second boom member is positioned on the first boom member;
• wherein the stop member and the closure member inhibit lateral movement of the wearpad in a direction parallel to the plane of the wearpad, and allow movement of the wearpad in a direction transverse to the plane of the wearpad, when the wearpad is positioned in the receptacle and the closure member is positioned in the fixed position, and the second boom member inhibits movement of the wearpad in the direction transverse to the plane of the wearpad, and wherein the closure member is attachable to the first boom member in the fixed position with one or more fasteners that extend in the first direction, and the first boom member has a slot that permits movement of the one or more fasteners in a direction transverse to the first direction.

A boom assembly comprising:

• a first boom member;
• a second boom member that is slidable relative to the first boom member in a first direction;
• a frame attached to the first boom member, the frame at least partially defining a receptacle;
• a closure member that is attachable to the first boom member in a fixed position proximate the frame and movable away from the fixed position, wherein the closure member cooperates with the frame to define a retaining structure when the closure member is positioned in the fixed position;
• and
• a planar wearpad that is insertable into the receptacle in the first direction when the closure member is moved away from the fixed position and the second boom member is positioned on the first boom member, such that the wearpad is positionable between the first boom member and the second boom member, wherein the wearpad has a first surface and a second surface that extends at an angle with respect to the first surface, and wherein the first and second surfaces contact the second boom member when the wearpad is inserted into the receptacle;
• wherein the frame and the closure member inhibit lateral movement of the wearpad in directions parallel to the plane of the wearpad, and allow movement of the wearpad in a direction transverse to the plane of the wearpad, when the wearpad is positioned in the receptacle and the closure member is positioned in the fixed position, and wherein the second boom member inhibits movement of the wearpad in the direction transverse to the plane of the wearpad;
• and wherein the closure member is attachable to the first boom member in the fixed position with one or more fasteners that extend in the first direction, and the first boom member has a slot that permits movement of the one or more fasteners in a direction transverse to the first direction.
