Thank you all, Will send you updated drawing with dim to get you an idea. I have to use rud lug to lift overhang plate. I calculated torque to 2.2 kNm each so will the rud lug of 3T on each be sufficient ? How to determine what size rud lug to use ? It will be weld on. Second question...

Hi Tom, Not climbing up the ladder just on levelled ground...this is different to other thread. Regards, Yashi

Hi All, Thank you very much for advice. Only reason i wanted to find this was to decide how many sections i should make of sheet if there are no mech aids and only human has to lift them. I did concept design to show sheet metal of 3m x 2m but now have to draw production drawing from lifting...

Hi Tom, Michler and Lnewqban, Thank you very much. Here is the link of video i found to determine torque which fits my situation. As far as wind loading is concerned, its 80kmph which comes to 62N. Another piece of info is, when its in upright position, it will be held by 2 pivot points on end...

I have situation where i have drawn a concept with 1 sheet covering width of box for model. But now i need to draw up the manufacturing drawings and it needs to lifted and assembled by 2 people. So i need to know if person weighs 70 kg how much weight they can lift without using mechanical aid...

Hi All, Thank you for the guidance. I will need to start making production drawings for this task. With all your inputs, i m pretty condident of getting it right. Do you reckon 20mm dia n 32nb pipe for hinge mechanism is sufficient or need to increase to 32mm rod n 40 nb or 50 nb pipe ? I...

Hi Tom, Thank u for sketch. You mentioned calculating torque of lifting plate. Wat are info required to work torque in this case ? Is there a formulae for an angle ? I hve hinged the overhang plate on a 20mm dia solid bar/rod and plate is welded to 32nb pipe. I would have thought with the...

Hi Tom, Thats great set of options. We had review meeting with managemnt n every1 agreed ground operated winch is better. If possible could you do hand sketch of other options i got the idea but will be gud to see them. All things on top has to be detachable so bolt down plate has to be...

Hi All, Thank you every1 who has helped me so far with their advice. I am down to last few queries to every1 who is following this thread. 1. Since the weight to be lifted is 350 kg eachover angle of 153 deg is it safe to use 700 kg capacity / rated hand brake winch in centre or use 2 x 500...

Hi there, Nearly a tonne was an approximation it was around 800 kgs cutting into half n then had to trim some distance to clear ends. Got to around 720 kg. N that angle was 90 + 63 = 153 was typo in writing 143. When u use 2 pulleys, does rope cable go alternatively up n down or can...

Hi Lnewqban, 117 to horizontal was for dimensioning but 143 is the angle the overhead needs to move or raised from its vertical position. Add them n u get 270 deg which is angle between horizontal n vertical faces. As far as fab goes, none on site once the container requires transportation...

Hi All, Thank you for valuable advise and tips. So far over 2 days we have come to conclusion, split the overhead extension, use hand brake winch which is self locking so it can hold on its own when released and calculate the wind load. so that makes each overhead to 350 kg and if i use...

Hi Lnewqban, Thank you for valuable advise and youtube links. Let's call top plate as overhead extension. How about i split the plate into 2 halves, that way weight of plates will be just 350 kg each n i can use 500 kg rating winch x 2. There won't be any issues with bending or coordination...

Hi Baluncore, the reason the terminology is different because Royal wolf is off the shelf product but we are modifying it to use the side as front. We are working on their side hence operationally, its our front. Regards, Yashi

Hi Thank you for insight both of you. I have done bit of search online. I found following winch and pulleys. I learned about Mechanical advantage of pulleys so more the pulleys weight bearing capacity on winch is that much less. So for using 2 pulleys, 800 kg will result in just 200 kg. Is that...
