摘要:
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 characterised in that 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. 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 characterised in that said apparatus further comprises a member (42) 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 wherein said weight compensating device (20) is arranged between said travelling block (6) or said top drive and said primary elevator (10). This invention also provides a method, a device and an elevator.
