What are the taboos for using a speed differential fall arrester?

The speed differential fall arrester is an important safety protection device, usually used in scenes such as high-altitude operations or cargo lifting to protect workers from falling injuries. When using a speed differential fall arrester, a series of usage taboos must be strictly observed to ensure its effectiveness and safety. The following are some key usage taboos:

1. Installation and hanging taboos

Low hanging and high use: The speed differential fall arrester must follow the principle of "high hanging and low use", that is, it must be hung on a solid and blunt-edged structure above the user, not below. Low hanging and high use may result in the inability to start the descent system in time and turn it to a locked state when falling, increasing the risk of falling.

Unsecured installation: The speed differential fall arrester must be installed on a solid support and ensure that the support can withstand the required load. Unsecured installation may result in the inability to withstand the impact force when falling, thereby losing its protective effect.

2. Taboos during use

Overload use: Do not use it in excess of the rated load of the speed differential fall arrester. Overload may cause damage or failure of the equipment and fail to provide effective fall protection.

Long-term use: Although the speed differential fall arrester is designed to be durable, long-term continuous use may cause problems such as overheating and increased wear of the equipment, thus affecting its performance and service life. Therefore, long-term continuous use should be avoided, and the equipment should be checked and maintained regularly.

Too large an inclination angle: When using a speed differential fall arrester for tilting operations, the inclination should generally not exceed 30 degrees. Exceeding this angle may cause the equipment to malfunction or increase the risk of falling.

Use of a kinked safety rope: It is strictly forbidden to use a kinked safety rope, which may cause the safety rope to be unable to be smoothly pulled out or recovered in an emergency, thereby affecting the fall protection effect.

Self-disassembly and modification: Users are not allowed to disassemble or modify the speed differential fall arrester by themselves, which may cause the performance of the equipment to deteriorate or fail. If necessary, it should be repaired or replaced by professionals.

3. Taboos for maintenance and care

Ignoring regular maintenance: The speed differential fall arrester needs regular maintenance and care, including checking wear parts, cleaning and lubricating transmission parts, etc. Ignoring regular maintenance may cause equipment performance to deteriorate or fail.

Improper use of lubricants: Although the key components of the speed differential fall arrester have been specially treated for wear resistance and corrosion resistance, lubricants may be required in some cases. However, improper use of lubricants (such as excessive use or use of inappropriate lubricants) may cause equipment performance degradation or damage. Therefore, the equipment manual or professional advice should be followed when using lubricants.

4. Storage and preservation taboos

Sun and rain: When storing and preserving the speed differential fall arrester, it is necessary to avoid adverse environments such as sun and rain, high temperature and humidity. These environments may affect the performance and service life of the equipment.

Random placement: The speed differential fall arrester should be placed in a dry, ventilated place without corrosive gases, and avoid contact with sharp objects to prevent scratches or damage.

In summary, the above taboos need to be strictly observed when using the speed differential fall arrester to ensure its effectiveness and safety. At the same time, users should also receive regular training and education to understand the correct use of the equipment and maintenance knowledge.
