Abstract
A lift and rotate dolly (10) functioning to allow a user to lift and rotate material (22) in situations where space is limited such as an elevator. The lift and rotate dolly (10) has a frame (12) which has a frame bed (12A) having a right-rear castor wheel (18RR), left-rear castor wheel (18LR), right-front castor wheel (18RF), and left-front castor wheel (18LF) mounted thereon. The lift and rotate dolly (10) further has a mast (14) securely mounted at a bottom distal end to the frame bed (12A). The mast (14) is vertically aligned and the frame bed (12A) is horizontally aligned forming a perpendicular angle therebetween. The mast (14) further has a mast slot (14A) positioned on a front side therein. The mast (14) further has at least one mast pulley (14F, 14R) rotatably mounted at a top distal end. The lift and rotate dolly (10) further has a lift (20) slidably mounted on the mast (14). The lift (20) comprises a lift pin (20) securely fastened at a front end to a lift plate (20B). The lift pin (20) is securely fastened at a rear end to a lift mast sleeve (20C) which is slidably mounted within the mast (14).
