A hydraulic lifting arrangement for moving a climbing screen, climbing formwork or other structure, vertically along a construction, comprises a hydraulic ram 1 and a mounting arrangement 100 for detachably mounting the ram 1 to a construction, the mounting arrangement 100 comprises a first part 2, which is either fixed to a first end of the ram 1 or mountable to the construction and a second part 3 that is conversely either fixed to the first end of the ram 1 or mountable to the construction, with the second part 3 arranged to receive the first part 2 for holding it captive. The first part 2 may move along a horizontal axis (A-A fig. 3) into engagement with the second part 3. The second part 3 may comprise a straight slot 4, closed at one end, the closed end being semi-circular. The slot 4 may be provided in a planar support member 6. The first part 2 may comprise a neck portion 8 to be received in the slot 4 and a head portion 9 connected to the neck portion 8 and wider than the slot 4 so as to constrain or prevent movement of the ram perpendicular to the horizontal axis (A-A fig. 3). Locking means 18 restrict movement of the first part 2 by blocking the exit of the neck portion 8 from the slot 4. Vertical loads from the ram 1 may be supported by a recess, opening or socket in the second part 3 engaging a conical, frusto-conical or spherical cap element 12 of the first part 2.
