Wearpad arrangement

摘要

A boom assembly includes a first boom member and a second boom member slidable relative to the first member in a first direction. A stop member that at least partially defines a receptacle is attached to the first member. A closure member is attachable to the first member in a fixed position and movable away from the fixed position. A planar wearpad is insertable into the receptacle in the first direction when the closure member is moved away from the fixed position and the second member is positioned on the first member. The stop and closure members 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, when the wearpad is positioned in the receptacle. The second member inhibits movement of the wearpad in the direction transverse to the plane.

主权项

1. A wearpad arrangement for use with two members, wherein one of the members is slidable relative to the other member in a first direction, the wearpad arrangement comprising:
a frame that is attachable to one of the members such that the frame at least partially defines a receptacle; a closure member that is attachable to the one member in a fixed position 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 wearpad that is insertable into the receptacle in the first direction when the closure member is moved away from the fixed position and the other member is positioned on the one member, wherein when the wearpad is positioned in the receptacle and the closure member is positioned in the fixed position, the wearpad is held loosely in the receptacle by the retaining structure, and the wearpad is inhibited from moving out of the receptacle by contact with the other member, and wherein the wearpad has a chamfer configured to be spaced away from the one member when the wearpad is positioned in the receptacle, and the chamfer provides clearance with respect to a weld bead on the other member.
