What is the service life of Railway Emergency G clamp?

The service life of Railway Emergency G clamp can be affected by a number of factors, and in general, its service life can be between 5 and 15 years.
Factors affecting its service life include:
Material quality: If made of high-quality, high-strength and wear-resistant materials, the service life may be relatively long. For example, fixtures made of high-quality alloy steel have better durability than ordinary steel.
Frequency of use: Frequent use increases wear and fatigue, which shortens service life. In areas where railway emergencies occur frequently, the number of times the fixture is used may make it need to be replaced in about 5 years.
Maintenance: Regular inspection, cleaning, lubrication and fastening maintenance work, can effectively extend its service life. Without good maintenance, performance degradation can occur in about 7 years.
Environmental conditions: In harsh environments, such as high temperature, humidity, and corrosive environments, fixtures are more vulnerable to erosion and damage. For example, in coastal areas, the salt brought by the sea breeze may accelerate the corrosion of the fixture, shortening its service life to about eight years.
Load: The greater the load, the greater the loss to the fixture. If often used to clamp heavy-duty railway tracks, it may reach the limit of its service life in about 10 years.
