Abstract: An apparatus for facilitating the connection or disconnection of a tubular to or from a string of tubulars, which apparatus comprises a weight compensating device (20) which can be suspended from a travelling block (6) or a top drive is disclosed. In one embodiment, said apparatus further comprises at least one bail (2) which can support a primary elevator (10) and which can, in use, be raised and lowered by said weight compensating device (20) to enable a tubular (32) to be raised and lowered with respect to a string of tubulars and which can move to a load bearing position in which it can raise and lower said string of tubulars. This invention also provides a method, a device and an elevator.
