Traction gas springs are gas-filled tubes containing a piston rod. When the rod is pulled out, the gas expands and pulls the rod back in. This is the opposite of a traditional compression spring, where the gas attempts to push the rod out. They are becoming more and more common and are quite safe to use, as long as you follow some simple safety tips.
Never dismantle the spring
The gas inside a traction spring is nitrogen, which is kept under high pressure. The spring may lose some of this pressure during its lifetime. Do not be tempted to re-fill the spring if you think it has leaked. Although the gas itself is harmless, the pressure is not. The spring could easily explode if you attempt to take it apart and could cause serious injury.
Don't tamper with the spring
Although the springs are quite strong, they are not designed to be tampered with or adjusted. Do not make any attempt to bend or squeeze the spring, or to weld it into place. The spring will be manufactured to work in a particular temperature range, so you should be careful not to heat it in any way. You should also be careful with the piston rod inside the tube — do not allow this to become bent, and do not attempt to paint it as this could stop it from working properly. You should not even attempt to lubricate the spring unless the manufacturer recommends it. It is more likely that it contains its own lubricant.
Do not use a damaged spring
A spring with any obvious sign of damage should be replaced immediately. Dents on the surface or a piston rod that appears to be bent are signs that the spring could be dangerous. You should also investigate how the damage happened so that it does not happen again.
Use safety devices
Finally, if there is any risk that someone could be harmed by a faulty spring, use safety guards and other features to protect your workforce. Some springs can be placed within locking tubes that provide protection if there is a sudden loss of pressure within the spring.
Traction springs are usually quite safe and there should be no risk to your workforce if you take simple precautions.
