摘要： An elevator for handling tubulars includes a first body part (11) coupled to a second body part (12) by hinged connection (13, 14) and slips (31, 32, 41, 42) coupled to each of the first and second body parts. On the backside the slips a member in the shape of a dovetail or spline is arranged which engages a complementary groove profile on first and second body parts. At least 25% of the length of the member is engaged with the groove at all times.
In another embodiment, a swivel includes an upper housing rotatably coupled to a lower housing; and a rotary union having a rotating body attached to the lower housing and a non-rotating body attached to the upper housing, wherein a axial bearing transfers load from the lower housing to the upper housing.
