A grabber (500) used, for example in the lifting and lowering of blocks, includes one or more arms (540) with a damped self-centering mechanism (570) ata distal end thereof. The damped self-centering mechanism dampens a contactforce received thereon and facilitates a self-centering of the dampedself- centering mechanism relative to the block when the arms are lowered through bores in the block. The mechanism further comprises one or more levers (575) located in the distal portion of the one or more arms, the one or more levers actuatable between a retracted position that allows the grabber to be lowered past a bottom end of the block and an extended position that allows the one or more levers to engage the block, the damped self-centering mechanism configuredto extend past a bottom surface of the block when the grabber is coupled to the block.
