If for example T2 1000 lbs in the case of a counterweighted take up the weight of the counterweight must be 2000 lbs That is because the 2000 lbs provided by gravity will be resisted with an equal and opposite force of 1000 lbs in each of the two strands of conveyor belt
In weightloaded takeup systems the tension weight must generate the minimum belt pull F 2 to achieve perfect grip of the belt on the drive drum spring pneumatic and hydraulic takeup systems work on a similar principle The tension weight must be able to move freely The takeup system must be installed behind the drive section
