Pulleys

2:1 Traveling Pulley

A-Simple 2:1

B-2:1 with Ratchet

C-2:1 Pulling Second Rope

This system is nothing more than a force multiplier turned around. One end of the line is attached to an anchor. The rope passes through a pulley and back in the direction of the anchor. The load is suspended from the pulley. The load is equally supported by both sides. When you pull up on the unanchored side you only need extend one half the force, but for twice the distance. Figure A portrays this in the simplest form. Note that this form is considered unsafe for live or critical loads.

Figure B is the preferred method for hauling a live or critical load. In this system we have added a ratchet cam. The ratchet cam is used to hold the load when sufficient force is not being exerted on the unanchored end.

Figure C shows how to use a 2:1 system to pull on a separate line. In this system we use an ascender (called the haul cam) to attach the traveling pulley to the load line. We place a second ascender (called the ratchet cam) below the haul cam. By placing the ratchet and haul cam on the load line the team can pull up the load line with the hauling system, set the weight on the ratchet cam, and then reset the haul cam to take another bite and haul up more of the load line. This same sequence is used with all other systems.

3:1 The Z-Rig

The z rig allows you to exert only one third the force for three times the distance. Notice that the z shape must be maintained otherwise it turns into a simple direction change and offers no mechanical advantages. As force is applied to the unanchored pulley it will move towards the anchored pulley until they meet. Set the ratchet cam by slightly slacking the hauling system behind the ratchet cam. Then reposition the haul cam by moving it towards the load. Repeat this procedure until the load reaches the desired level.

4:1 Piggyback Rig

The piggyback is nothing more than a 2:1 system hauling another 2:1 system for a total mechanical advantage of 4:1. To set up a pig: divide the haul system line into two legs by tying a figure 8 on a bight at the mid point. Attach the knot to a suitable anchor. Use one leg to set up a 2:1 system with the haul cam attached to the load line. The free end of this 2:1 portion is terminated at the second pulley by attaching it to the carabiner hole on

the pulley. The other leg is used to set the second 2:1 system through the pulley with the terminated line. A ratchet cam is added to allow the team

to reset the hauling system.

Ratchet Cams

A ratchet cam is used to hold the load while the haul cam is being repositioned. Do not consider the ratchet

cam to be a safety. Its sole purpose is to hold the load on a temporary basis. A ratchet cam may not hold

under shock or heavy loading. A potential problem is shock loading of the ratchet cam. This can occur as

the hauling team pulls the line through the system. An unanchored ratchet cam can move along with the

line, creating slack in the system (see Figures A & B). This slack can be the cause of a shock load to the

entire system. To prevent this from occurring a person, or shock cord can be used to prevent the cam from

moving as the line is hauled up as shown in Figure C.

Multi-Line Hauling System

This system is used to provide equal tension on two lines. Common uses are to pretension a dual line tyrolean traverse (highline) or to pull with equal force at several points on an object such as an overturned trailer that needs to be put back on its wheels. By adding additional anchored pulleys, traveling pulleys and ascenders this system can be adapted to pull on 3, 4 or more lines as needed.

Ascenders In Hauling Systems

Notice that the illustrations in this catalog show a number of different ascenders used as ratchet or haul cams. Mechanical ascenders or ascender hitches can be used to achieve the same end results. However, one must be aware that no system is 100% fail safe. Mechanical ascenders (Gibbs, Jumars, Petzls etc.) can cut the rope under high or shock loading. Ascender hitches have also been known to slip until the load comes to rest on a solid surface under the same conditions. There are no magic formulas one can give you that can tell you which type of ascender to use for any particular job. Do consider the manufacturers load ratings and recommendations when selecting mechanical ascenders. Temper this with training and practice before utilizing these techniques in the field.

See the Ascender section on page 2 for rope grab devices.

See Tripod/Confined Space Rescue section on page 135 for mechanical advantage systems.

CMC ProSeries Digital Pulley

UL Classified to NFPA 1983-General Use. Knowing just how much rope you have out can be a significant help in planning an evacuation. What if you are using a capstan winch for pulling the rope and would like to keep a constant speed? The CMC ProSeries Digital Pulley can eliminate the usual, very rough estimate of the distance to the patient. While not every rescuer needs the system data provided by the Digital Pulley, it can be integrated to make the system safer and more efficient. The pulley has an integral swivel, keeping the digital displays visible. The pulley measures distance in feet or meters and the speed in ft./sec or m/sec. The large displays are easy to read and the distance display remains on until reset. The on/off button is recessed. Battery life: 1-2 years. The CMC ProSeries Swivel Pulley has the same hardware features as the Digital, but without the electronics. Includes:

Sealed ball bearing for maximum efficiency

Double Rope Rescuemate

This ingenious device combines a 2.5”(60mm) double sheave pulley with an ascender cam. It is this cam that acts as the fall arrest mechanism holding the load between hauling operations. If a conventional pulley is required the cam can be disengaged allowing the rope to flow freely, this operation can be done quickly and is easy to reverse. Unlike sealed units, the Rescuemate can be maintained or re-rigged in the field and it has no hidden internal mechanisms to malfunction. The pivoting side plates on the pulley allows the user to put it on the rope at any point. It is designed to lift or lower, life or load. With the addition of extra pulleys you can increase the mechanical advantage on the Rescuemate as required. It will accommodate ropes from 5/16” to 5/8”(8 to 16mm) in diameter. Maximum load at cam on a 1:1- 1985 lbs.(900kg). Safe working load at cam on a 1:1- 440 lbs.(200kg). Weight 28oz.(795g).
