Two possibilities: With adjustable pulley: It is necessary to elevate the end pulley or to arrange a pit in the ground depending of the path (the pit must be equal to the height of the door). The balancing mass must be lightly over the half-weight of the door. With adjustable pulleys + deflection pulleys: Use additionnal pulleys ref. 8145F. Then the balancing mass must be doubled but the path is reduced by half.
