How to calculate required Power in KW for Trolley (having four wheel, dia approx 400mm) having load caring capacity 10.2 Ton and moving at velocity 10 mtr/ Min.?


This is for selection of Motorised GearBox

1. trolley will be use for moving ring type of product up to 4.5mtr dia. and will run on flat horizontal plan on rail track (no slope).
2.not required to accelerate, trolley should be move 10mtr/min. constant valocity.

P = F * V is it right? if yes then
how to find F and starting Torque Required?
How to consider Friction Force in formulae?
