ABSTRACT:
A dual elevator system and method which, in one embodiment, includes two elevators and a table for supporting one or both of the elevators thereon, for shuttling an elevator between well center and offset standby positions, and for hands-free coupling and uncoupling power and control to an elevator on the table by remote actuation. Each elevator has a rear power and control connector and hitch which connect to complementary connectors and hitch located on a table shuttle mechanism by remote actuation. The table shuttle mechanism is driven by an actuator coupled between the shuttle mechanism and table frame which moves an elevator hitched to said shuttle mechanism between well center and standby positions.
