How to climb a concrete pillar without claws?

When it becomes necessary to climb a pole without a ladder or a tree without branches, you have to use various methods. Professionals use a set of devices for this.

There are several reliable ways to solve the problem: 1. Stairs. 2. “Ballerina” is a specialized basket lift on a boom. 3. Invite a professional.

If reliable methods are not possible, consider how to climb a tree yourself. Before climbing a tree or pole, take care of insurance. If belaying with a rope attached above is not possible, try to wear something made of rough fabric. You can put the jacket on with buttons on the back so as not to injure your chest, stomach or anything else important if you move incorrectly. The basis of climbing is to provide the necessary grip on the surface of the tree.

How to climb a pole

Not often, but there is a need to climb a power line pole on or near your suburban area. And although such a rise to heights requires professional skills, many do it on their own. How to climb a power line or street light pole in this article.

About the task of climbing a pole

The task of climbing a pole is not everyday in country life. This problem arises when connecting a house to power supply and is often solved by professional electricians. It would be strange if everyone who was not too lazy climbed the poles of overhead lines and, even worse, power lines and solved their problems without the participation of the servicing electric company.

However, in theory and in life, a domestic situation may arise in which you will need to climb onto a VLI pole yourself. The simplest example is to change the lamp in a street lamp located on a pole near your house.

The task of climbing a pole is interesting in itself, like the task of quickly climbing to a height in a country house. You don't necessarily need to climb a pole. More common tasks are to climb to the base of the roof or the gables of the second floor.

Of course, climbing a pole is not exactly the same as climbing from the street side to a second-floor window, but some solutions may be similar.

VLI pole height 0.4 kV

The power line of a suburban area is designed from wooden or concrete supports, less often metal poles 9-9.5 meters high. (read about power line supports). When installing such a pole, it is buried 2-2.5 meters into the ground. (read about installing the support). It is not difficult to calculate that the end of the pillar remains about 7 meters above the ground. It is clear that no one needs to climb to the top. To work, it is enough to rise to a working height not exceeding 6 meters. How to climb a pole 6 meters high.

How to climb a pole?

Professionally, the task of climbing onto a support is solved with the help of a special electrician’s device called claws or installer’s manholes. They are put on the legs and, when climbing up a pole, they cling to it, creating support for a person’s mobility.

For wooden supports, mounting claws marked KM are used. They only work on wooden supports and wooden supports with a concrete “stepchild”. (read what a stepson is)

For concrete supports of type SB 95, universal manholes LU or universal claws KLM are used. Their catching part is not round, but rectangular or trapezoidal.

The manholes are put on the feet on hard shoes. Fastened to the leg with straps. The safety of the person climbing depends on proper securing. Manholes cost, by today's standards, inexpensively, about 2500-3500 rubles.

Here is a description of the LU-1 manholes:

Universal manholes LU-1 are used to climb onto a reinforced concrete pillar of trapezoidal cross-section VLI type CBll0-la, CB95-1/2a, SV105. The hole opening is adjustable. Includes carbide studs and leather straps.

If there are no holes to climb onto the pole?

The absence of professional pole climbing does not eliminate the need to climb onto a support. The one-time problem of climbing to a height can be solved alternatively. It is enough to have a convenient transformable ladder in your household.

Transformable ladders allow you to rise to a working height from 2.7 to 6 meters. They are made of aluminum, so they weigh no more than 10-11 kg and can be easily carried by one person. Moreover, the design of transformable ladders allows them to be compactly folded and stored without taking up much space.

Transformation of stairs allows you to use them as:

Double-sided ladder; stepladder;
Working platform;
L-shaped ladder.

stepladder platform extension ladder ladder transformer assembled

The last option is suitable for climbing a pole.

Conclusion

You can climb the pole yourself, and in several ways. However, before you go to heights, think about your safety, both electrical and at height.

Specialized manholes for concrete supports

Working at high altitude is always accompanied by a certain risk of injury to the worker. You must use only proven equipment and adhere to safety rules.

There are many climbing tools available today, but the best proven ones are concrete pole climbs, made specifically for climbing tall poles.

But you need to be able to choose even this equipment in order to avoid the most common mistakes.

Brief description of the equipment

Modern manufacturers produce high-quality manholes for quick and safe climbing onto concrete supports. All of them have not only positive properties, but also distinctive performance characteristics. That is why experts divide such equipment into three main groups:

Manholes on concrete. Designed for round and trapezoidal supports.
Universal fitter claws. They are used for round metal and wooden poles (it is worth noting that in the modern world wooden poles are practically not used).
Claw-holes. Equipped with a specific control solution, which is especially effective in relation to trapezoidal reinforced concrete pillars.

Claw-holes are considered the most popular, since their functionality can be used in relation to all standard supports. However, manholes are used only on those pillars that are indicated in the accompanying documentation. Of course, any electrical installation company should have quality claws at its disposal, especially if it is involved in the installation and maintenance of power lines.

Modern manholes are made exclusively from high-quality materials, so they can be used in almost any climatic conditions. They tolerate sudden temperature changes well (from -30˚С to +55˚С).

Areas of use

Multifunctional manholes on concrete supports are designed to quickly deliver an installer to a damaged power line.

You simply cannot do without such equipment when laying and servicing the cable, especially if urgent repairs to the electrical network are needed.

The team does not always have the opportunity to use large vehicles, which is why manholes are considered simply an irreplaceable option. The main challenges are often related to cramped buildings and difficult terrain.

Quite often, manholes are used to quickly replace LED lighting on street poles. This trend is due to the fact that there is a lot of work, and using specialized equipment is impractical.

The huge advantage of this equipment is that the kit includes two strong feet, as well as a universal waist belt, which must be looped around the main post and fixed on the master’s belt using a powerful carabiner.

This simply eliminates the possibility that the installer will somehow deviate from the support and disrupt the necessary platform grip.

Separately, it is worth noting that modern claws can be inserted and removed from the main part of the support without any effort; just a simple movement of the leg is enough. The presence of special studs significantly enhances the final grip. At the moment when the weight of the installer presses on the platform, each pin clings to the concrete, which increases contact with the surface.

Scheduled inspection

Each type of equipment that is used by craftsmen to carry out electrical installation manipulations must be subject to routine inspection and heavy load testing. This category also includes pole holes.

When a product passes a static load test, a certain force (more than 1350 N) is applied to the fixing belts. In this case, it is important to note that the load line must pass through the center of the footrest.

In addition, experts have developed a step-by-step guide that will help novice technicians properly maintain cats:

First of all, it is necessary to inspect the manholes. The technician must check the fastening of all parts (sickle, spikes), as well as the reliability of the stitching of the belts and the strength of the buckles. It is worth noting that each tenon must be secured with a special lock nut, which is clamped all the way and sharpened in the correct direction.
The reliability of the spike should be checked on a regular pole, the diameter of which should be equal to the number of the claw.
Experts assure that a high-quality spike can easily withstand a load of up to 140 kilograms without any deformation or damage to the welds. In addition, under the influence of such a load, buckles and belts should not be damaged.
As for possible deformations, they need to be checked exclusively by measuring the rise of the tenon and the solution of the equipment before and after undergoing scheduled tests.
At the final stage, all manholes on which defects have formed after mechanical loads must be removed.

Manufacturers note that concrete manholes are considered mandatory equipment for installers who professionally install and repair power lines. When purchasing such equipment, you should always pay attention to the fact that such devices must not only be of high quality, but also completely safe for use.

The employee must study all regulatory documents that describe in detail the requirements and rules for the use of cats. You should not neglect these rules, as such behavior is fraught with serious injury and damage to the limbs.

Design differences

Standard installer's manholes are presented in the form of ordinary cats, which until recently were actively used for wooden poles, but are now suitable for any supports. This equipment is distinguished by its reliability and durability. Manholes consist of two main elements:

As for belts, several layers of backlash or rawhide can be used to make them (each layer must be stitched with strong nylon thread) or two-layer leather, which is stitched in two layers. It is worth noting that for high-altitude work on concrete pillars, claws of a universal design are used. The mounting hook has a very unusual shape, which can be similar to a trapezoid, sickle or rectangle.

For strong adhesion to the surface of the support, the hook is equipped with special spikes. Such manholes are made of high-quality steel, which can additionally be treated with anti-corrosion paint. Due to this, the service life of cats is significantly increased.

Modern holes for concrete pillars can be used for trapezoidal supports.

Depending on the manufacturer, such models may be equipped with special carbide-type inserts that reduce possible slipping and wear of the claws.

It is worth noting that the total weight of the manholes can be 5 kg. Structurally, such equipment looks like this: an adjusting insert, a footrest, a fastening belt, an engagement bracket.

A metal pipe is used to make the mounting hook; this design must be equipped with reliable fasteners. But the footrest has plates with recesses that are designed to fix two layers of clamps.

Using fitter claws is quite simple - you just need to wrap the straps around your shoes, securing them securely. The installer climbs up the pole thanks to self-locking, where spiked hooks engage the pole.

It is worth noting that the more weight falls on the claw platform, the more reliable the fixation on the support will be. Equipment will be considered high quality if it is manufactured in accordance with GOST or TU standards.

In addition, professional climbers must have appropriate quality certificates.

Alternative equipment option

Manufacturers most often draw the attention of their customers to the fact that the maximum service life of such equipment is 5 years. After a year, the manholes must be inspected for damage and deformation. If necessary, some parts can be replaced.

That is why many craftsmen often decide to purchase logs for concrete supports from scratch.

In order to avoid the most common mistakes, the master must be aware of how to properly test the strength of such equipment.

Despite the fact that used claws do not have any markings or instructions for use, they must meet a number of requirements:

Be strong and durable.
Support the weight of the installer.
Have removable spikes.
They are distinguished by an easy type of adjustment.

Operating rules

Domestic and foreign manufacturers clearly regulate the basic standards for the use of claws. You can read all the rules in the attached instructions. As practice shows, for the correct operation of manholes it is necessary to adhere to the following recommendations:

Each item of upcoming events is always agreed upon in advance, and all actions on the ground are worked out in detail. The executive must have permits that confirm his admission to work at height.
Repairs to any power line must be carried out only when the power is turned off. The technician must use specialized insulating gloves and rubber grounding devices.
Modern assembly manholes are designed for high-altitude work on supports that are specified in the accompanying documentation. In this regard, it is strictly forbidden to use claws of an inappropriate shape, since the contact with the surface will be inaccurate, which can result in injury to the master.
Before starting to use the joists, the technician must check the date of the last inspection for damage. In addition, welds cannot be ignored and must be checked for cracks and corrosion. All bolted connections are carefully inspected and tightened. You should always remember that at high altitudes, destroyed platforms can provoke a fall, and this can lead to injury or even death.
Those belts and buckles that secure the master’s leg should also be checked before each lift (they should not be torn or pulled out). If any defects are found, then using the manholes is strictly prohibited.
In accordance with manufacturers' standards, manholes must undergo thorough maintenance at least once every six months, after which a corresponding report must be drawn up, which must indicate the date of subsequent inspection.
Do not neglect the safety belt, which always comes with manholes. This is due to the fact that climbing onto the support without such equipment is strictly prohibited, as the master may simply fall.
Experienced craftsmen categorically prohibit climbing those supports where the grounding line is laid, since the spikes of the cats can simply stick into the cable and flash through it.

Considering the many advantages of manholes for concrete supports, experts consider them an alternative to automobile towers with a cradle. This trend is due to the fact that work is completed much faster and requires less financial costs.

All the above rules are a kind of basic safety precautions that must be observed when working at heights using electrical claws.

Any violation of the integrity of such equipment is fraught with negative consequences. Experienced specialists recommend not to take risks and use only factory-made manholes.

The main dangers may be associated with the fact that homemade equipment does not pass any strength tests.

Claws for climbing poles and trees

Fitter's claws (fitter's manholes, crampons) are devices used by electricians and high-rise workers to safely climb concrete and wooden power line supports and trees. Despite the widespread use of specialized automobile towers and telescopic lifts, mounting claws still have a very large list of situations in which their use is more appropriate and convenient: when space is cramped and there is no possibility for equipment to approach power lines, when hydraulic mechanisms break down or fail lift at the work site.

Simple claw device

Design and principle of operation

The simplest manholes for concrete supports consist of 2 elements for attaching to shoes, each of which consists of the following main components:

Oval foot support with transverse reinforcements;
2 straps holding the foot on the platform;
“Sickle” is a rectangular grip with 4 conical spikes attached at an angle of approximately 600 to the supporting platform.

Climbing onto a reinforced concrete pole using a similar device occurs as follows:

The electrician securely fixes the manholes on his shoes using belts;
Approaching the pillar, he grabs it with the grips of each of the elements of the claws;
The electrician climbs the pole, thanks to the fact that the claw grips, which he alternately rearranges in the vertical plane, located at an angle to the supporting platforms, bite into the concrete with their spikes and prevent slipping.

How to climb a concrete pillar without claws

During the operation of power lines, unexpected situations often arise, which is why they have to be repaired.

And in such cases it is very important that this work is carried out as soon as possible. To quickly solve problems that arise, you need special equipment.

First of all, you can’t do without such a device as cat’s claws or monter’s manholes.

The presence of such equipment for any organization that is responsible for the maintenance and installation of power lines is mandatory, since without it it is impossible to ensure long-term operation of power lines.

Purpose and purpose

The main purpose of assembly manholes is to create conditions for quick ascent to a vertical pole where it is necessary to perform certain work. Quite often, this device is used in situations where it is necessary to carry out repair, installation or maintenance work.

Heels

If you need to climb a high tree, cut a wooden beam into pieces 15-25 cm long, hammer two nails into each and drive them into the tree trunk at the required distance from each other. This creates something like a ladder, eliminating the need for claws or spurs. The method is quite labor-intensive, so it is better to use it when there is a need to climb a tree several times or it is impossible to ensure sufficient safety by other means.

A rope thrown over a high branch will allow you to easily climb any tree. There is a difficulty in this method - throwing a rope. To make it easier, you can use a light rope or fishing line, and then use it to stretch the main cable. You can throw the rope with a grapple, a spinning rod, a bow/crossbow, or a slingshot built on the ground.

The operation of power lines, like any other equipment, is impossible without damage or malfunctions that occur at the most inopportune moment. In order to eliminate them in a timely and efficient manner, it is necessary to have suitable tools and devices available.

To eliminate malfunctions in the operation of power lines, there are special tools, and even equipment that can be used to quickly get to the location of the breakdown. Such equipment is monter's claws (cat's claws, monter's manholes), which help you easily climb up the pole.

This type of equipment is an integral part of specialized equipment for performing work related to power lines, so they must be in the arsenal of any enterprise related to the repair of power lines.

Do I need to trim my budgerigar's nails?

Watch how your bird walks. If, when walking, its fingers and the surface are in complete contact, then the claws are of normal length and the bird can move calmly. Excessively overgrown claws interfere with the pet’s movement, constantly cling to uneven surfaces when walking and, as a result, can cause serious injuries. If a parrot's claw cracks, it will bleed profusely and cause sharp pain. Therefore, to the question “does a budgie’s claws need to be trimmed?” the answer is clear - it should always be done, and on time, so as not to encounter the problems listed above.

Climbing Techniques for Beginners

Climbing walls for beginners are the most optimal place for initial exercises, as this will allow you to pay maximum attention to the movements and placement of your legs and arms in comfortable conditions. It's worth noting that not all walls are good for beginners. Walls that are too steep can require a lot of strength. The ideal place is a rock with a slight slope, on which the weight of the body is transferred to the legs and not to the arms.

Climbing outdoors is also suitable, since it is not difficult to find a variety of rocks with a low inclination angle. A significant disadvantage is that you will depend on weather conditions: wet rock is quite slippery, and cold does not in any way add to the pleasure of climbing. The ideal place would be low boulders with a generous layer of grass and soft sand around. First, you should figure out whether you can go back down. Put on your climbing shoes and helmet, wipe your feet dry on a pant leg or a napkin, and go!

A rock with a convenient inclination for starting is 25-30°. You can climb such rocks without using your hands. To save effort, avoid too high or wide steps, try to rely only on the frictional force - the adhesion of the sole and the rock.

About the electrician's claws

If the trees need to be completely felled, and not the tops cut off, then the following method will do. You can climb the tree using the branches just like that, or you can attach a long ladder. Typically, the knots are denser in the upper part. Tie three ropes above the center of gravity of the tree (you can determine it by eye, usually a little above a third of the height). Stretch it in a triangle and secure it to the surrounding trees or to strong stakes driven into the ground (pipes, rails, etc.). Do not tie “dead” knots; it is better to use a double grasping knot. Sawing from below as usual. Leave the stump higher. I washed down and removed the trunk in the direction of the planned “fall”. If the saw is pinching, you should work with an axe. Give a little slack to the rope (opposite to the direction of fall). Use a crowbar (pipe) to move the trunk from the stump. Tighten your stretch marks. Saw off the next piece. So, little by little, we shorten the trunk from below. NOTES. It is better to cut in the fall, when there is less foliage on the tree. Use nylon (braided) rope with a diameter of at least 8 mm. Better than "ten". The rope must be tested. It is better to do the work not alone, but with competent (understanding the task) assistants. The method was repeatedly used on trees with a butt thickness of up to 30 cm. Thicker ones did not have to be cut in this way.
