I need to know weight a man can pull the hand lift's pallet with comfortable operation, weight range 500 to 2500 kg. Distance of operator working is 80 meter, about 80 time/shift (12 hour).
General, How much weight can a man pull?

Are you looking at the acceptable amount work or the maximum amount of work?

There are also a lot of other factors which need to be considered including the how level the floor is and what the effective coefficient of friction or frictional losses in the system.

If you assume a 1% effective of coefficient of friction the total amount of work to pull the 2500kg 1600meters is 392,240 Newton meters. This would be easily do able, but if you increase the effective coefficient of friction to over 10% you would be approaching the work the person could do especially if the worker also had to lift the weight prior to moving it.

Thank you Niel Leon, for suggestion

I'm looking at the acceptable amount work. Not include other factors due to there is flat floor
barring only hand lift pallet truck .
