The Probst CT75750 AIRLIFT® Base Kit is a one-man back pack vacuum lifter. It is used for installing pavers, slabs, porcelain etc. and works by providing a secure grip on the materials for easier movement. The unit is designed for lifting and moving slabs, pavers and even porcelain tiles in a safer, easier, and more ergonomic manner. Because AIRLIFT is electric, it does not require an air compressor like most comparable tools. The backpack-style vacuum is also very lightweight and easy to maintain.
