How does the Z Drag work?
This is accomplished with the use of carabiners which act as pulleys and allows for a person to pull a much heavier load than with a rope tied directly to an object. The Z Drag needs to be set up and "manned" carefully.
How do you use a Z-Drag?
The Z-Drag, although originated for rescue of boats pinned in a river, can be used to help you lift anything heavy. A person can be hauled up a cliff face, a snowmobile or ATV can be un-stuck or heavy items such as large game can be hoisted into the air from a tree for butchering.
What is the physics of a Z Drag boat?
The physics are the same for the Z-drag. Even though there is only one handle on the boat, the three parallel lines are like three arms pulling, splitting the load and multiplying the force. The Z-shape is what matters, as it gets three lines working together.

What is AZ pulley?
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. The basic arrangement results in pulling the hauling end 3 times the distance the load is moved, providing a theoretical mechanical advantage of three to one.
How do you calculate pulleys?
Calculate the tension in the rope using the following equation: T = M x A. Four example, if you are trying to find T in a basic pulley system with an attached mass of 9g accelerating upwards at 2m/s² then T = 9g x 2m/s² = 18gm/s² or 18N (newtons).

How does AZ rig work?
The Z-rig is a convenient pulling system that is quick and easy to set up and can provide a tremendous boost to the pulling power of ground workers. The most basic form of the Z-Rig uses just one rope which is tied to the load, an anchor point, 2 single pulleys and one or two prusiks.

What is a Z-drag?
The Z-drag is a 3:1 mechanical advantage system, which will enable you to move a heavy boat through the water with less exertion. Let me explain it like this: imagine you have a 100-pound bucket of cement. When you grab the handle you will struggle to lift it, as your arm is lifting all 100 pounds.

What is a Z drag?
A Z-drag is a system of ropes and pulleys that create a 3 to 1 mechanical advantage. This typically is used in rescue situations where a simple pulley system wouldn’t be adequate to haul the weight.
Where to place pulleys on haul line?

Can a Z-drag pulley be used for rescuing patients?
There may also be cases where these systems prove helpful for rescuing patients. If rescuers know that they might struggle with the retrieval and hoisting of larger victims that are packaged on boards, a Z-drag pulley system could make things easier.
What is a Z drag?
The “Z” drag (so named because the rope looks like the letter “Z” if you turn your head sideways) which gives you a theoretical 3:1 mechanical advantage, is one of the fundamental setups of crevasse and rock rescue. After you've done it a few times, most people get the hang of it. But if you haven't rigged it in a while, or if you're doing it under the stress of a real rescue situation, setting it up efficiently and correctly can be a challenge. (I’ve seen some quite experienced climbers have a complete brain fade trying to do this if they’re out of practice . . .)

Z-Drags can come in handy, especially while creeking here in the mid-Willamette Valley where most of our runs are centered around boulder gardens. I've made it a habit of bringing my pin kit on pretty much every run, as it always seems that you need it when you don't have one with you.

A Z-Drag can have a massive impact on the amount of weightthat you can handle as a rescuer. If you have a heavy object that you need tomove, tying a rope to one end and pulling isn’t going to work unless you happento have the world’s strongest man on your team. It …
So How Do You Set Up A Z-Drag System?
- Make sure that you have the right gear together for the job
- Figure out where your anchor point is going to be
- Connect your prusik knots for a strong, reliable pulley system
- Make sure that you attach the rope to the right place on the object you’re moving
Other Considerations
- Even if there is no victim to transport or anyone within thevehicles or boats being moved, you need to ensure that you work safely at alltime to protect your team and anyone in the area. A failure with the connection point could send the boat/carcrashing back down to where it started. Breaks in the pulley system or anchorpoint could alter the force and position of the rope, potenti…
