How can the safety fall arrester ensure the safety of working at heights?

Nowadays, aerial work has entered the homes of ordinary people. Many industries involve high-altitude operations, such as building cleaning, bridge construction, exterior wall painting, plank road construction, power maintenance, etc., all of which are high-altitude operations, and there is a huge operational risk.

The safety fall arrester is a commonly used aerial work protection device that can quickly lock and lock falling objects within a limited distance to avoid accidents.

The high-altitude workers must wear a safety fall arrester before each operation, and do an inspection to ensure that everything is normal before putting it into use.

How to maintain high altitude anti-dropping device

In order to ensure that the high-altitude fall arrester can maximize its function, daily maintenance is essential, so how can the fall arrester be simply and quickly maintained?

First of all, after the use of the fall arrester, check whether the parts are damaged, whether the cover is lacquered or worn, whether the safety hook has cracks, whether the safety rope is open or not;

Secondly, wipe the surface of the fall arrester clean, if there is rust, it should be rusted;

Finally, apply anti-rust grease to prevent surface rust.

What is the safety inspection method when using the hook?

What is the standard for the use of the hook that should be scrapped and its retirement?

Hoater takes you to understand:

Hook safety inspection

1. The hook for the human-powered hoisting mechanism is tested with 1.5 times the rated load as the test load.

2. The hook for the power-driven hoisting mechanism is tested with 2 times the rated load as the test load.

3. After the hook is removed from the inspection load, there shall be no obvious defects and deformation, and the increase of the opening degree shall not exceed 0.25% of the original size.

4. For the qualified hook, the mark should be printed in the low stress area of ​​the hook, including the rated lifting weight, the factory or factory name, the inspection mark, the production number and so on.

Hook scrap standard

Hooks should be scrapped when one of the following conditions occurs:

1 crack;

2 The dangerous section wears up to 10% of the original size;

3 opening degree is increased by 15% than the original size;

4 hook body torsional deformation more than 10 °;

5 Hazardous section of the hook or plastic deformation of the hook neck;

6 hook thread is corroded;

When the 7 hook bushings wear up to 50% of the original size, the bushing should be replaced;

When the 8 hook spindles wear up to 5% of the original size, the mandrel should be replaced.

Is the helmet insulated?If there is a shelf life

The helmet is divided into a general work type helmet (class Y) and a special work type helmet (class T). The general working helmets only have anti-shock protection performance, and are used in the working environment where there is a risk of impact, such as construction and shipbuilding; the special operation refers to the protection risks specified in the product standards, in addition to the protection risks of the general operations. Special performance requirements, such as flame retardant, low temperature resistance, insulation and other functions, of which T4 is an insulating helmet, suitable for power places, so T4 helmets are also called "electrician helmets", "electric helmets" and so on.

Not all helmets are insulated, and only T4 helmets are suitable for insulation. Each helmet has certain technical indicators and scope of application. Therefore, it is necessary to purchase the target product according to the working environment.

Insulation performance electrical helmets are "adapted to work environments that may be exposed to three-phase AC power below 400 volts." That is, workers who may be exposed to a three-phase AC working environment below 400 volts should wear a T4 insulated helmet. For example, various types of power plants, power supply companies, power construction companies, telecommunications and other communications construction companies.

After the impact of the helmet, no cracks or dents can be used. Even if the above conditions do not occur, the helmet cannot be used all the time because the helmet has a shelf life.
