What is Static Loading? (A Definitive Guide)
A static load is a mechanical force applied slowly to an assembly or object. Static loads do not change over time but remain constant, allowing tests to be conducted to determine the maximum loads that can be withstood by structures such as bridges or floors in tower blocks. Static loading can also be used to work out the strength of different ...

Working Strength vs. Breaking Strength
The Service Factor in a belt helps handle the "shock load" introduced into a belt on loaded start-ups and at other times when the belt is subjected to "unusual" tensions in the system. Higher Service Factors may also provide higher modulus in a belt specification resulting in lower elongation in a given application.

How To Remove Static Electricity From The Conveyor Belt
The first step in eliminating static is to measure it. If you can feel the static charge or receive shocks, then the charge is already way to high and needs to be addressed. Human feel static at 2000 volts, but components can be damaged with as little as 100 volts. A static field meter can be used to measure the static charge on your conveyor.
