Abstract
A wall block lifting apparatus can include a support member, first and second adjustment members, first and second posts, and first and second gripper elements. The adjustment members can be adjustably coupled to the support member such that the adjustment members are movable between a lifting position and a release position. The first post can be coupled to and extend from the first adjustment member, and the second post can be coupled to and extend from the second adjustment member. The first and second gripper elements can be respectively coupled to and extend from the first and second posts, and the first and second gripper members can be configured to securely engage a wall block when the first and second adjustment members are in the lifting position and to release the wall block when the first and second adjustment members are in the release position.
