Abstract This invention relates to an access cover lifter, such as those used to lift access covers, manholes, grates etc. in roads and pavements so as to gain access to subterranean workings. The lifter comprises an elongate shaft, a first end of which carries a cover lifter key and a ground-engaging fulcrum spaced therefrom so as to engage a ground beside the cover when the key is engaged therewith, wherein a second end of the shaft is configured to be urged downwardly toward the ground to pivot the lifter about the fulcrum to raise the first end and thus dislodge the access cover. 18 17 Figure 3A Figure 3B
