ABSTRACT:
The present invention provides transport apparatus for transporting and aculating an article into and out of a housing having limited access, and includes a lifting beam having a curved shape to which is attached a lifting assembly. A hoist device is connected to the lifting assembly for raising and lowering the entire transport apparatus and also includes a worm-drive assembly for moving the lifting assembly relative to the lifting beam to thereby articulate an article about a first axis. In addition, one end of the lifting beam includes a rotational mechanism which is connected to a second worm-drive assembly. Operation of the second worm-drive assembly allows the article to be rotated relative to the lifting beam which allows the article to be rotated relative to a second axis. The combined operations of hoisting and movement about the two axes allows the article to be articulated in any direction for insertion or removal from a housing having limited access.
