There are three basic pulley systems. They are the 2:1, the Z-rig, and block and tackle (Figure 6.1; see also Figure 6.7, Figure 6.8, and Figure 6.12). Most systems described in this section are configurations that use combinations of the 2:1 or 3:1 Z-drag.
Pulleys and Mechanical Advantage Systems | CMC PRO
When we build a mechanical advantage system to move a load in this situation, a simple “Block and Tackle” system such as a 2:1 “Ladder Rig” or a 4:1 with double sheave pulleys at the top and bottom can be used.
s of basic pulley systems. They are the 2:1, the Z-rig, and block and tackle (Figure 1; see also Figure 7. Figure 8, and Figure 12). Most systems described in this section are configurations that use combination.
Block and tackle - Wikipedia
A block and tackle is characterized by the use of a single continuous rope to transmit a tension force around one or more pulleys to lift or move a load. Its mechanical advantage is the number of parts of the rope that act on the load.
Tackle or Purchase. The two types of tackle systems are simple and compound. The simple system uses only a single line, the compound, more than one line. The power gained by tackle is also known as Mechanical Advantage, referred as the relationship between load being lifted and power required to lift it. The mechanical advantage can be ...

Z-Rig Construction - The IPS Group
Jan 21, 2018 · The 3:1 Z-Rig is one of the quintessential mechanical advantage system used by rescuers. This system when offset requires 1/3 of the rope than the 4:1 block and tackle system.It can be converted easily to a 6:1 compound by the addition of a single pulley and is a powerhouse due to its ability to be

Z-drag - Wikipedia
A Z-Drag or Z-Rig is an arrangement of lines and pulleys, effectively forming a block and tackle, that is commonly used in rescue situations. [1] The basic arrangement results in pulling the hauling end 3 times the distance the load is moved, providing a …
