A device for lifting a steel reinforcement mat includes a grid of parallel rods in a first direction and, placed thereon and fastened permanently, parallel rods in a second direction, each according to a predetermined mesh width. The device has a hoisting frame suitable for being secured to a hoist. The hoisting frame has supporting elements on opposite sides positioned in such a way that when the hoisting frame rests on an uppermost steel reinforcement mat of a stack thereof, each supporting element is located in a respective mesh. The supporting elements are configured to slide in the first direction in such a way that during lifting, the supporting elements each support with a respective supporting surface exclusively rods in the second direction of exclusively the uppermost steel reinforcement mat. The supporting elements on the opposite sides slide away in the opposite direction to each other.
