KALLER Safety features reduce the risk of damage and injuries

PED approved for a minimum of 2 million stroke

KALLER gas springs are designed, manufactured and tested to withstand a minimum of 2,000,000* full strokes according to PED 2014/68/EU at max charging pressure, max operating temperature and for all approved mounting methods.
*Estimated value for fatigue.

Customer value
High safety and reliability during the entire product life.

Repair kits and training through KALLER with partners, providing increased efficiency and reliability.

Protection against overstroke

During an overstroke, conventional gas springs may burst and components may come loose and be ejected.

KALLER gas springs make a difference
In the event of an overstroke, the patented safety protections are designed to evacuate the gas in a controlled manner. Either the cylinder tube is deformed in a predefined way (A), or the piston rod destroys the safety plug in the bottom of the gas spring (B).

Customer value
Safer working environment and reduced risk of damage to the tool.

Possible cause
No mechanical stop in the tool for limiting the stroke, or improper installation.

Protection against overload

If, for any reason, tool components should get stuck and the piston rod should be freely released from its compressed position, conventional gas springs may pose a safety risk as the piston rod is not being retained in the gas spring.

KALLER gas springs make a difference
Optimized guide and a patented safety stop on the piston rod support user safety. If the speed is too high during the return stroke, the piston rod automatically breaks off and the integrated safety stop destroys the seal, which results in the gas spring being depressurized in a controlled manner.

Customer value
Safer working environment and reduced risk of damage to the tool.

Possible cause
Jamming components, such as a blank holder, cam, ejector or stripping function, getting stuck and suddenly getting loose.

Protection against overpressure

If the internal gas pressure exceeds a maximum allowable limit, conventional gas springs may burst and pose a safety risk for tools and operators.

KALLER gas springs make a difference:
If the internal gas pressure exceeds a maximum allowable limit, the safety lip will be activated. The gas will be evacuated and the gas spring is depressurized in a controlled manner.

Customer value:
Safer working environment and reduced risk of damage to the tool.

Possible cause:
Too high charging pressure or intake of external liquid such as drawing fluid.

Training

The safety features described above may vary for each gas spring model regarding function and cause of failure. Always secure that the gas springs are mounted, installed and used according to information from KALLER. For more information or training, contact KALLER with partners.

For safe handling of gas springs and other pressurized products, always make sure that the nitrogen gas is evacuated before carrying out any work on the product. If a safety feature is activated, the gas spring must not be repaired or used anymore. It has to be replaced with a new gas spring.
