ABSTRACT
The International Masonry Institute (IMI) has developed and demonstrated a prototype of a new, electronically controlled mechanical device it is calling a Mechanically Assisted Mason’s Aid, or ” MAMA,” that enables bricklayers to easily lift, handle and set into walls masonry units that weigh up to 90 pounds each. The device is especially useful for laying of block walls where the masonry units are heavier than a worker can reasonably handle.
