We are a group of roofers from Boston local 33. We were tasked to install 2000 to 3000 lb concrete slabs on the roof of a new building project. At first we struggled with crane straps, which was a slow process and set us back a good deal of time. Our employer purchased the Kenco Multilift for us, and it made the job a hell of a lot easier. Thank you very much and keep innovating.
