A hoist is a machine designed to lift and lower heavy loads that are too heavy for manpower alone. They are usually attached by an automatic lifting hook to a rotating arm or mobile guided by rails placed on ceilings of industrial buildings. Small hoists can be handled by hand, while heavier hoists are electrically powered by motors.
Construction hoists, also known as construction elevators or material lifts, are essential tools in the building construction industry. They are designed to lift or lower a load mechanically, applying a lesser force than the weight to be moved. Hoists consist of a motorized drum with a chain or rope for lifting or lowering objects. Lever hoists, also known as ratchet hoists or come-alongs, allow operators to pull, lift, and position materials in horizontal or vertical directions through a lever or crank mechanism.
A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. The upper part of a hoist system connects to the hoist’s lifting ropes or chains via a steel frame, securely suspending the cage. Hoists are necessary for building construction to secure ease and security in transporting materials and personnel.
In rigging, hoists lift or move heavy objects and support hanging loads like cargo, construction tools, and vehicle engines. Hoists are typically attached to a gantry crane and used to lift heavier car parts (such as the engine) out of the vehicle. Floor-mounted hoists include hook mounted, lug-mounted, and trolley mounted hoists. Hoists use ropes, chains, or braided wires connected to a drum, rollers, or another turning tool to raise and lower objects in a bucket or other container.

📹 How To Lift Heavy Beams by Yourself
The Ultimate Handyman shows you how to lift large beams by yourself using simple tools from harbor freight and common …
I did this when I built my huge wooden patio by myself. I basically used a bunch of tie downs and strap a taller beam next to my posts and run a piece of lumber across and mounted the hoist. It worked like a charm. People were shocked how I manage to get 4x10x20 beams up by myself lol. i love finding solutions.
Super supportive. I have been lifting a number of different building materials on a house build that I am working on, mostly solo. I actually considered those very same chain hoists and I made the exact same lifts that you did out of 4x4s, yours were much more stout and I will go back and reinforce with the Simpson hardware….I even bough and used the same 1/2″ eye bolt. Amazing we were on the same track. Thank you so much for this article, so supportive.
I am using this tip for sure. Thank you. I liked subscribed and hit the bell on this. All that aside this is not just a little OP but a lot OP. It’s always good know the limits of things. There are great references to help people calculate wood weight, and also load capacities such as what weight a 4×4 over a horizontal span can support. I’m not creative enough to come up with the solution you did but hopefully encouraging folks to do this background research can help safety, cost and level of waste. I found info out there that puts your beams each at about 390 lbs. which is a weight that shockingly can be supported with a single 4×4 at the center of an 8 ft. span. Hopefully this comes across helpful and not rude.
