The trigger device is part of the main device for lifting along vertical planes (mountains, high-rise buildings, training slides). When climbing, use only the main rope (not a safety analog), and also use additional clamps, safety fuses. Consider the features of some modifications and reviews about them.
Gripping knot
Such a trigger device is also called a prusik. The element is a short piece of rope connected to the ring by means of a paired marine unit. The diameter of the part should be exactly five millimeters, which allows you to fix it as tightly as possible. The assembly is mounted on the frame using several fixing methods.
Below are the two most popular nodes:
- The first option is a node with one attached end and the second again repeating element. This method is used to temporarily hold the slings (when crossing or equipping the system with additional insurance).
- Triple reshnur. It can be dangerous if used improperly. The rules for organizing such a fastening are as follows: the base must be thinner than an additional rope, when pulled, it can be very tightened. In addition, it is possible that the prusik does not grasp after the first jerk, which is fraught with its complete incapacity.
Pros and cons
Prusik advantages:
- Light weight.
- Convenient and easy mounting to the main system.
- Universality.
- Ease of use.
- Does not critically affect rope wear.
This trigger device has certain disadvantages:
- The need for periodic weakening of the Prusik, which slows the climb.
- Possibility of slipping the knot under load, which is fraught with grinding the rope knot.
Mechanical lifts
These modifications are positioned as advanced Prusiks. Almost all devices work on a single rope. For example, the Wild Country Ropeman cable and launch device is compact and efficient. It consists of a unit with a built-in carbine and kamlot.
Positive sides:
- Simplicity of operation.
- Reliability and durability.
- Does not aggressively affect the braid.
Among the cons:
- It is not intended for use with double rope.
- Has a relatively decent weight.
Some mountaineering triggers can be used when climbing the bottom of the rope. They are called "magic plates." The functional model includes a pair of carbines. At the same time, the product does not require aggregation with additional analogues, however, lifting is not simple compared to a professional device, since it takes a certain time to master this device.
Petzl Triggers
This brand is known in the market for the production of rescue and climbing equipment. We begin our review of the lifts with the Tibloc series. This device has an original design. The device is devoid of moving parts, which makes it as simple as possible to operate. Against this background, the device is characterized by rather aggressive teeth, which can slip if installed incorrectly, damaging the rope and disorienting the user. After several trainings, its operation will not cause problems.
The advantages of the tool include light weight and the absence of moving parts, and among the shortcomings is slow operation and the requirement of certain skills to use.
Ascender
This trigger device can be compared with luxury cars by analogy. The unit is quick, easy to use, safe and indecently high price. The unit is ideal for lifting. The device is equipped with an ergonomic handle, a thoughtful lock with a latch and a lock. You can control it freely with one hand. The design provides a special hole for installing a locking carabiner. There are additional slots for additional pedals and clips.
Advantages of the model: the most thoughtful design and ease of use, absolute ease of use. Among the minuses can be noted a lot of weight and high cost.
Petzl Croll Series
This option is a light version of the previous model (no pen). But, there is one feature here - a Croll type construction. In fact, it is a special torso lifter that allows you to climb on perfectly vertical surfaces. The fire rope-trigger device is attached directly to the safety loop, fixed by means of a similar tie in the neck area.
Using this device in conjunction with a system such as Handled Ascender (double foot loop) makes it possible to simultaneously place both hands on the upper element, and the legs on the lower loop. This solution makes lifting easier and less tiring for the user.
Pros:
- Quick work.
- The ability to facilitate climbing.
- Low weight.
The disadvantages include inconvenience in overcoming obstacles due to the angles at the base of the structure and additional equipment on the rope.
Mini traxion
This trigger device - "landing". That is, it is designed to use the movement of goods up with the possibility of autonomous insurance and lifting. As a lift, the device is not as comfortable as the analogs with handles, but it is very effective.
The main advantage of this unit is its convenience when lifting goods. Of the minuses can be noted not very convenient operation, a lot of weight and considerable time in preparation for work.
Petzl shunt
The "Shunt" model is focused on insurance when descending a rope. However, it can be used for lifting. The main advantage of this fire escape device is the ability to aggregate simultaneously with a pair of ropes, if necessary, urgent descent. The user can release the shunt and manipulate faster than with any other device. The main thing is to learn how to properly operate the Shunt.
The advantages of this element include the possibility of using two ropes, as well as a gentle attitude to them during operation. The negative points include a lot of weight and bulkiness.
Self-locking analogues
A safety device of this type is designed for the structure involved in the lifting system. They can only be operated in the lower zone from one of the elements discussed above. This is due to the fact that they have an autonomous locking function. The big plus of this unit is that you have to take one device less with you, and it also provides a quick descent. As an example, consider one of these devices (the rest of the analogues work on an identical principle).
The “Gris-gris” modification is one of the most popular devices in this category. It is focused on overcoming bench obstacles, comes complete with a lift and a handle. The model allows for quick descent if necessary. In addition, the set includes the trigger device itself, a grill, a lift with a handle. You can use the device for "pedal" descent.
Magic Plates
Among these modifications, the most popular brands are Petzl Reverso and Reversino. They are used on the bottom cord of a rope when climbing. For operation, you need a pair of carbines.
Benefits:
- The possibility of double use, if necessary, can be useful in unforeseen circumstances without a special lift.
- Ergonomics and thoughtful design.
Disadvantages:
- The device is not for beginners, to use it will require certain skills.
- Additional carabiners are required.
Eight trigger device: description
This modification is one of the most popular in the organization of insurance in mountaineering, industrial action and climbing. For industrial purposes, an element with a clamp is mainly used, which allows you to tie a rope in two or three knots. A kind of mustache, fangs or teeth can act as stoppers. Devices without clamps belong to the sports type. They differ in the possibility of organizing downhill.
The G8 trigger device with a lock is oriented for aggregation with ropes with a diameter of 9 to 12 millimeters. It is worth noting that when using this device, you can use a single or double rope.
User reviews
Consider the feedback from users of the trigger device of the trigger mechanism of the Bento type (horned eight). Owners note the convenience, ease of use and reliability of the device. Among the minuses: short horns, the possibility of twisting the rope.
Otherwise, consumers note that this type of slingshot is one of the best devices in its class. It is understandable in terms of operation for every beginner, has a high level of reliability. Despite all the shortcomings, the model in question is optimal for industrial and professional climbers, as well as amateur climbers. In general, users recommend this item for all climbers.
