How to Perform Performance Tests on the Webbing Variety
Tests of safety belts of this type are carried out as follows:
- The belt is attached to the mannequin.
- A 400 kg load is attached to the end of the back strap by means of a rescue rope.
- The dummy is raised to a height, held for 5 minutes, and then lowered.
- The belt is removed and examined.
The safety belt PP 1 is considered to have passed the tests if during this procedure there was no destruction of the load-bearing elements or any irreversible changes in appearance.
After that, the belt must also be checked using the second method. This will be an additional guarantee of reliability.
Operating rules
In addition to the expiration date, the authorized person inspecting the personal protective equipment must inform the employee about the rules for using the safety equipment. To do this, you should study the instructions for use, which are supplied with all factory-made products. In order to use the harness correctly and not to disable it before the warranty period of service, you should know and do the following:
- before starting work, the equipment must be put on and tightened the belts of the belt, as well as the leg straps;
- adjust the height of the attachment point on the back while adjusting the shoulder straps;
- connect the shoulder straps with the belt using the carabiners intended for this;
- in the presence of a shock-absorbing connecting system, it must be secured with a leash to the anchor device.
An important circumstance for performing work at high altitudes is taking into account the negative factors affecting the condition of the equipment - these may be inconsistencies in temperature regimes with those stated by the manufacturer for his product.

Sewing
Cut tool belt do it yourself is necessary in accordance with the pattern. All parts must be laid out on the seamy side of the selected material and circled with chalk, soap or a sewing marker. Do not forget to add seam allowances - in this case, the product will turn out to be the correct size, if this is not done, the pockets and all parts of the belt will be smaller
Allowances may already be added on the finished pattern - pay attention to this. Such a nuance can affect its functionality and practicality.
We start with the belt itself, on which the branches will be located. The wider the product, the better, it is also worth taking care of the rigidity, the length is chosen depending on the size of the waist. For adjustment, you need to use special fittings - latches or carabiners. Velcro will also look good, if necessary, it can be easily replaced with a new one. All options can be found in stores with sewing accessories and consult with the seller, he will definitely tell you a good option from all available.
Now let's get down to designing the pockets properly:
- hemming of one free edge with finishing stitching;
- processing with finishing materials.
This processing option will not allow the edges of the fabric to climb in different directions. And this can lead to the loss of the tool, which will be extremely unpleasant. Use rivets to strengthen the pockets.
When you have finished with the preparation of all the branches, you need to place them on the belt as the final result will look like.To try on, pin all the details with pins, if everything suits you, then you can start sewing on a typewriter.
How to make a tool belt with your own hands?
For beginners, it is recommended to choose the model that is as easy to manufacture as possible. Before starting work, you need to find out the appropriate volume of the future product and determine the location of all pockets. For clarity, it is advisable to draw a sketch.
For the manufacture of such a product, you can use various materials (for example, tarpaulin, unnecessary jeans, straps). To make such a belt from old jeans, you will need the appropriate material, a sewing machine and scissors.
Stages of work:
- The belt must be cut off from the jeans. Through the existing fastener, it will be further attached to the waist.
- Now cut out the back pockets and sew them to the belt. If the pockets are riveted, this will be an added advantage when folding consumables and small tools.
- Next, you need to cut off a small piece of fabric from one of the legs and fold it in half, forming a pocket. Then, leaving 2 cm at the top for attaching this pocket to the belt, sew the sides of the pocket and lay an additional 2 vertical line seams, thus dividing it into 2 more pockets, which can later be used for small tools.
Construction belt
A product of this type must be large enough to fit all the tools required for work. Since in the process of use a product of this kind is subjected to significant stress, it is necessary to use extremely durable elements of good quality for its sewing.
The construction belt without shoulder straps (with a button) is convenient because it does not unfasten during operation. The model with straps is fixed on the chest and on the back, without hindering movement during use. This allows you to use more tools in your work.
Mounting
must be thought out in detail to prevent falling from a height in the event of a force majeure situation
The mounting belt must have reliable fasteners that can be placed in different places depending on the specifics of the work.
In addition, this type of product has small compartments for small tools and hammer loops.
In such attributes, you can keep a fairly large number of tools with you, which is very convenient. Products of this type are often used by electricians in their work.
Types of assembly belt bags
- shoulder (very popular due to its low cost, but have soft, quickly deforming walls, and quickly lose their original appearance);
- waist (look like a small tablet equipped with pockets, hooks and loops);
- in the form of a vest (the most ergonomic type of such organizer, in most cases made from a denim vest).
What must be done before starting work
Before proceeding with the production task, you must make sure that the safety belt is in good working order. At the same time, they check:
- The presence of markings confirming that the belt has been periodically tested in service.
- There are no cracks, tears or deformations on slings, straps, ropes and straps. No traces of corrosion are allowed on metal elements. The straps should be tightly braided.
- The carabiner must open freely. If it sticks, the equipment must not be allowed into operation.
Pay attention to the technical serviceability of the belts, of course, when buying. It is also imperative to check this equipment for a warranty from the manufacturer.
These obligations are usually valid for two years from the date of purchase of goods. If there is a guarantee, in the event of a breakdown, you will need to present a completed instruction manual.
In what cases is this or that variety used?
If work is to be done in hover mode, a safety belt with a saddle strap is used. To prevent the installer from overturning (for example, from a post), a strap-free equipment is used to fix the body in a given position. When carrying out work in wells and tanks, shoulder straps are usually used. The version with metal slings is used when it is necessary to complete a task in conditions of increased fire hazard.
To work in certain modes (for example, when washing front windows), belts with a special saddle strap should be used, fastened on the chest unit, connected to the fastening rope.
