Roofing Swing-Hoist

We have been tasked with designing and manufacturing a small electric-powered roofing hoist, specifically engineered to lift a maximum of 1,000 lbs from a 60-foot building. The hoist must be designed for easy assembly and disassembly on the job site, with minimal parts to ensure quick mounting and dismounting from the location. The design requirement is that it should be lightweight, making it easy to transport and set up, without compromising on safety or reliability.
