Lifting And Material Handling: Fill & Download for Free

(A2A) - Thank you.Mr. Andrew Goh has actually summed it up pretty well already.Mjolnir was an enchanted weapon. Odin casted an enchantment that only those that are worthy will be able to weild Thor's hammer. Doesn't matter how strong you are, if you aren't worthy, then you cannot lift it. I'm looking at you, Hulk.For Stormbreaker, there was no enchantment. Thor simply needed a weapon that was the “Thanos killing kind”.Quill objects by stating that they should all have that kind of weapon and Thor responds that they are not strong enough. Not worthy enough, but strong enough.(Groot was able to lift it because it was simply just two pieces of metal prior to him cutting his arm off to use as the handle.)Both Mjolnir and Stormbreaker are made from the same material, and that is mystic Uru metal. Very indestructible (unless you're Hela) and very heavy.To sum it up:Only select few are able to lift Mjolnir because they need to be worthy as stated by Odin's enchantment.Anyone who has the strength will be able to lift and wield Stormbreaker as there is no type of enchantment on it.Therefore,Thanos was able to lift and wield Stormbreaker, because he had the strength to do so.Lifting Stormbreaker ≠ WorthyNow, could Thanos theoretically lift Mjolnir?Only if the hammer finds his cause, beliefs, and morals to be worthy.

Have you seen a baby picking up a toy from the floor?Perfect. That's the right way.It’s a shame we forget this good technique as we become adults.We end up doing this.. everyday... everytime...That's wrong.Perhaps, this is one good habit adults should learn from children.Have you noticed what went wrong here?So, what's the big deal?Improper manual handling can result in fatigue, and lead to injuries of the back, neck, shoulders, arms or other body parts. Two groups of injuries may result from improper manual handling:Cuts, bruises, fractures etc, due to accidents (immediate)Damage to the musculoskeletal system of the body (muscles, tendons, ligaments, bones, joints, bursa, blood vessels and nerves) as a consequence of gradual and cumulative wear and tear through repetitive manual handling. These injuries are called ‘musculoskeletal disorders’. (long term)Then, what is the correct technique?There is no such thing as a completely ‘safe’ manual handling. Remember, the best way is to go for mechanical handling, wherever possible.Good handling technique for lifting:Health & Safety Executive, UK highlights the good handling technique as follows,Think before lifting / handling. Plan the lift. Can handling aids be used? Where is the load going to be placed? Will help be needed with the load? Remove obstructions such as discarded wrapping materials. For a long lift, consider resting the load midway on a table or bench to change grip.Adopt a stable position. The feet should be apart with one leg slightly forward to maintain balance (alongside the load, if it is on the ground). The person should be prepared to move their feet during the lift to maintain their stability.Start in a good posture. At the start of the lift, slight bending of the back, hips and knees is preferable to fully flexing the back (stooping) or fully flexing the hips and knees (squatting).Get a good hold. Where possible the load should be hugged as close as possible to the body. This may be better than gripping it tightly with hands only.Keep the load close to the waist. Keep the load close to the body for as long as possible while lifting. Keep the heaviest side of the load next to the body. If a close approach to the load is not possible, try to slide it towards the body before attempting to lift it.Don’t flex the back any further while lifting. This can happen if the legs begin to straighten before starting to raise the load.Avoid twisting the back or leaning sideways, especially while the back is bent. Shoulders should be kept level and facing in the same direction as the hips. Turning by moving the feet is better than twisting and lifting at the same time.Keep the head up when handling. Look ahead, not down at the load, once it has been held securely.Move smoothly. The load should not be jerked or snatched as this can make it harder to keep control and can increase the risk of injury.Don’t lift or handle more than can be easily managed. There is a difference between what people can lift and what they can safely lift. If in doubt, seek advice or get help.Put down, then adjust. If precise positioning of the load is necessary, put it down first, then slide it into the desired position.How much weight can you safely handle?So, how much weight can you safely lift and handle? It depends on a number of factors,the Loadthe Individualthe Task involved andthe EnvironmentTo asses the maximum load, this chart below can be used as a rule of thumb,Each box contains a guideline weight for lifting and lowering in that zone.First, decide which box or boxes the lifter’s hands pass through when moving the load. Then, assess the maximum weight being handled. If it is less than the figure given in the box, the operation is within the guidelines.If the lifter’s hands enter more than one box during the operation, use the smallest weight. Use an in-between weight if the hands are close to a boundary between boxes.The guideline weights assume that the load is readily grasped with both hands and that the operation takes place in reasonable working conditions, with the lifter in a stable body position.As you can see, the guideline weights are reduced if handling is done with arms extended, or at high or low levels, as that is where injuries are most likely to occur.Importantly, Lifting capacity reduces by 50% if the load is away from body.Hope these practical tips are useful in reducing the risks.

May I present to you the humble container:Source: Gazouya-japan, CC BY-SA 4.0 via WikipediaA standard shipping container is around 20-feet long and can hold up to 53,000 lbs. (~26 tons) worth of goods and materials. The 20-foot container has become the industry standard for shipping containers through a measure called the Twenty-foot Equivalent Unit or TEU for short.Currently, the largest container ship in the world is the OOCL Hong Kong, commissioned in 2017. It has maximum capacity of 21,413 TEUs. Here she is, making her first port-of-call in Europe at Felixstowe in Suffolk:Source: Vessel FinderThe world’s busiest container port is located in Shanghai. Each day it stacks and unloads around 100,000 TEUs worth of containers, or the equivalent capacity of five ultra-large container ships like the OOCL Hong Kong.Source: Marine Vessel: Shanghai Container TerminalThe Great Pyramid at Giza is comprised of approximately 2.3 million stones weighing an average of 3 tons each [1]. Assuming average container weight of around 14 tons [2], this is equivalent to around 490,000 TEUs.This means that from a single large port in China, once every five days the equivalent weight of the Great Pyramid of Giza is loaded onto container ships and shipped thousands of miles to places all over the world.So do I think modern-day humans could handle building the Great Pyramid if we really had to? Yeah … I am pretty sure we got this.Notes:[1] Source: Live Science: How Much Would It Cost to Build the Great Pyramid Today?[2] Source: Maritime Executive: Filling Ultra-Large Container Ships
