Gravity is free, available all the time and is fast If the conveyor rises high enough above the ground at any location to allow enough vertical travel to accommodate belt stretch, this is typically the most preferred takeup option. Cons. Most conveyors do not rise above the ground more than 10 m at the discharge pulley.
