Abstract
A transfer boom adapted for suspension from a reciprocal shuttle carriage comprises a boom arm having a plurality of interior passages extending the length of the boom arm. These passages define air passages, thereby eliminating the need for exterior hoses. A T-shaped cavity is provided within the exterior walls of the boom arm. A boom mount, having Venturi cups or grippers is detachably mounted to the boom arm within the T-shaped cavity by a T-bolt. This enables the boom mount to be mounted anywhere along the length of the boom arm. The T-bolt provides for easy removability of the boom mount from the boom arm.
