Lifting apparatus 10 for use in lifting a planar member 12 such as a lid for a railway cabling service duct, a paving slab or a manhole cover which has first and second opposed edge regions 14, 16 comprises: a releasable arrangement 20 to hold the planar member 12; a first pivot portion 22 providing a first horizontal pivot axis 24 for turning the apparatus 10 to raise a first edge region 14 of the planar member 12; and a base member 26 which can move to a position below the raised first edge region 14 to provide a supportive base for the apparatus 10, wherein the base member 26 serves to support the first edge region 14 in the raised position and provides a second horizontal pivot axis 28 for raising the second edge region 16 while the first edge region 14 remains raised. The releasable arrangement 20 may clamp the planar member 12 between relatively pivotable first and second jaws 30, 32 which may be held in position by a lock including a latching, collapsible arm 56. A long arm 52 and grip 54 may form a handle. The base member 26 may include at least one wheel and a foot portion 66 which may fit over a structure such as the wall of a duct 18.
