Strap with ratchet mechanism: description, dimensions, instruction

The organization of transportation activities pays much attention to the preparation of equipment and consumables. Auxiliary devices in many ways and ensure the reliability of transportation of goods on a variety of modes of transport. Also in construction, it does not do without insurance devices of a suitable format. One of the most important elements of such equipment is a strap with a ratchet mechanism, which reliably fixes the load in its original position until the transportation process is completed.

General information about tie straps

Outwardly, this belt resembles a wide belt, which is used to insure people in cars. The main material of production are textile fibers of different properties. In particular, polyester is the most common as a practical, wear-resistant and high-strength base. Also, the straps for securing the load are equipped with a ratchet mechanism. This is a kind of lock, which allows you to exercise sufficient tension when fixing the tape.

Distributed and modification of the belt in the form of a ring device. In this case, the fastening is carried out as a result of the information of the two ends of the tape and their reliable fixation. Usually the belt is a tightening ring with a ratchet mechanism used to insure small-sized loads. Transportation of large volumes of containers, as a rule, is realized by fixing belts with hooks from two ends.

Tape dimensions

The width of such tapes usually vary from 25 to 100 mm. This choice depends on the size of the load and the requirements for holding the load. As for the length, it can be from 3 to 10 m. Short belts are usually used in domestic economy - for example, for transportation of small loads in the trunk or on the trailer. Large-scale building structures are often transported using 10-meter tapes. In assessing the characteristics that the belt with a ratchet mechanism has, it is important to take into account and maintain a tie-up force. This parameter can vary on average from 1 to 8 tons. Accordingly, the higher this value, the safer the transportation will be organized. Another thing is that the reliability of the event largely depends on the technical performance of the attachment itself. Still, the cases where the belts are torn, are much less common.

User's manual

The process of attaching the belt consists of several stages. First, raise the handle of the ratchet mechanism by pulling a special latch to it. Further in the formed passage it is necessary to pass a belt on necessary length. It is important to consider that before this operation the tape should not be twisted or wrinkled. Then the belt must be tightened with the help of the ratchet handle - for this purpose it is necessary to carry out movements up and down. As the application instruction notes, the ratchet straps should be checked for tension and during transport. The fact is that after a while the cargo can sink and the belts become weaker. Therefore, at certain intervals, responsible persons should perform a revision of the strength of the fastener action. The very same fixation is carried out with the help of the lock bolt - the handle goes down and locks the mechanism. To release the belt, you must also pull the latch toward you, and then raise the handle of the device up to the stop.

General recommendations for the use of belts

First of all, the use of belts is possible solely for the purpose, that is, for fixing a load suitable for the parameters. Regardless of the dimensions of the cargo, at least two tie belts should be used, which will ensure optimum transport reliability. If tapes with polyester fibers are used, it is important to consider the temperature regime. This material can only be operated safely in the -40 ° C range up to 100 ° C. In addition, tightening belts with tensioning devices are often used for cargo insurance with outstanding cutting and piercing edges. If it is not possible to provide complete pre-protection of the structure, then it is necessary to carry out point insulation with the help of linings or wireframes. And this measure also applies to containers with a rough surface. With prolonged close contact with abrasives, even polyester can get damaged, so it must be insured against such risks.

How can you use straps to secure the load

Sometimes, when making a fastening using a tie strap, some deviations from the rules of operation may seem more rational, convenient and economical. But not all of them are combined with the concepts of reliability and safety. In particular, technologists do not recommend hooking hooks directly onto the tape, deforming the hardware components, tie the knots, and also increase the load relative to the normative. It is important to remember that a strap with a ratchet mechanism also requires compliance with certain rules of care. After each operation, it should be cleaned and rinsed, but without the use of strong chemicals. And especially you can not use the same abrasives in the form of rough brushes for cleaning the surface of the tape.

Conclusion

The category of compression-type belts is widely represented on the market in different versions. The average cost of the kit is 500-700 rubles. For this money, you can get a quality polyester tape with a width of about 100 mm. If necessary, a belt with a ratchet mechanism can be supplemented with other auxiliary devices. For example, if you do not plan to perform an annular fixation, you will need hooks. Today, manufacturers are releasing and double-locking devices, which increases the reliability of fastening. Do not ignore and personal security issues. The rules prescribe to performers to carry out such operations in helmets and gloves.
