<p>An apparatus for manipulating and transporting equipment such as electronic equipment racks is engageable with a rack in either its upright position or its horizontal position and is controllably positionable to rotate the engaged rack to a horizontal position for transport and vertical position for installation. The apparatus comprises a horizontal mainframe (11) which is supported on casters (60) so as to be easily rollable. The mainframe (11) supports a battery-powered drive unit coupled to a first piston manipulator (25), one end of which is pivotally attached to the mainframe (11) and the other end of which is pivotally attached to rotatable rack-support mast (31). The rack support mast unit (31) contains a second piston manipulator (55) one end of which is attached to the support mast (31) and the other of which is attached to a translatable rack engagement subframe (81) having an engagement footplate (101) at one end of the rack support mast.</p> |
