Schemes of Manual fly lines with fixed pulley 1 - Simple fly line2 - Counterweight lineThe Counterweight line neutralizes the weight to be lifted by means of weights arranged in an appropriate Counterweight cage (CW) equipped with guides (G) that ensure its stability.

Manual fly lines with compound pulley (fixed + mobile) In the scheme, the so-called Gun tackle with 4B - Tackle blocks that act as mobile pulleys and the upper ends of the ropes fixed with a clove hitch (N) to the supporting structure.From a mechanical point of view, it is a simple machine which halve the weight to be lifted, but also halving the lifting speed and requiring longer ropes: compared to simple and counterweighted lines, for each pulley it is necessary to add a length of rope equal to the lifting height.

Of irreplaceable practicality, the Manual fly lines are used for modest loads to be lifted with ease and speed, such as wings, borders, backdrops, screens and light scenes.
Heavier loads can be handled by arranging the Manual fly lines in the form of the Gun tackle fly facility, which however limits their practicality and speed of movement.
They are used both in stages with Fixed pulleys structure systems and in those equipped with Flyloft with mobile blocks or with Fixed blocks for flyloft, where for their simplicity they remain in use even alongside sophisticated motorized systems.
The lifting of the load takes place by means of textile ropes which are fixed to the ground to a Mantegno or to a Horn cleat with a specific knot.
At the other end the ropes are usually tied with a clove hitch knot to a lifting point or to a batten.
For light loads and for bars up to 4 m in length, the Cantinelle are used, for higher lengths and loads the Top battens are used.
