Abstract
A side lifting boat and a tool assembly is disclosed. The tool is detachably engageable to selectively lift a boat. Both boat and tool are anti-rotationally engageable by the tool's upper and lower projections at its forward end fitting into a correspondingly shaped space defined between the outer (non-wafer-carrying) surface on the side of the boat. The boat's corresponding space permits the lifting tool to be moved into the space and into position between two fulcrum points that stabilize the boat/tool assembly from anything other than a small relative angular rotation.
