The present invention provides a manhole cover lifter having a key to be located in the manhole keyhole and a lever arrangement to provide the mechanical advantage for lifting the manhole cover. The key may be directly attached to the lever, or indirectly attached thereto by a lifting bar. A manually actuated, hydraulic manhole cover lifter comprises a frame mounted on wheels and adapted to straddle a manhole. An actuator is mounted on the frame. The actuator comprises a cylinder connected to a pump a magnet is connected to the cylinder for engagement with the metallic manhole cover. In a second embodiment, the lifter includes pivotal legs in order to be more compact for storage and transport.
