To deposit a reinforced concrete lintel, there are only two solutions: to release it on each side of the opening and to deposit it of a single block, or to destroy by chipping and / or mechanical cutting. Whether the lintel was cast in place or prefabricated, it is normally part of the masonry surrounding it, which makes it difficult to deposit it in a single block. It is anchored often enough the argement on both sides, from where the necessity to release it over all its length. Be careful not to destabilize the masonry!
