Gas Spring Locking Safety Tubes
Gas Spring Locking Tubes & Safety Locking Shrouds for Enhanced Operator Safety
Independent mechanical protection that helps prevent accidental closure whenever a gas spring loses pressure, becomes damaged or is subjected to unexpected loading.
While gas springs are widely used to support lifting, counterbalancing and controlled movement, many industrial applications also require an additional level of mechanical protection. Gas spring locking tubes and safety locking shrouds are designed to help prevent accidental closure if a gas spring loses pressure, becomes damaged or is subjected to unexpected loading. Depending on regional terminology, these products are also referred to as gas strut locking tubes, gas strut safety locking shrouds, gas spring safety tubes or gas strut safety sleeves.
Unlike a conventional gas spring, a locking tube does not generate lifting force. Instead, it acts as a secondary mechanical safety device that helps secure heavy lids, access panels, machine covers and other moving components while maintenance or inspection work is being carried out. This additional level of protection can significantly improve operator safety in applications where unexpected movement could create a potential hazard.
At Newtone Gas Springs, we manufacture gas spring locking tubes for OEM manufacturers and industrial equipment builders requiring dependable safety solutions. Each locking tube is designed to work together with our Gas Springs Manufacturer | Standart Gas Springs, providing reliable mechanical support without affecting the normal operation of the application.
Our gas spring locking tubes and gas strut safety locking shrouds are available in a variety of sizes to match different gas spring dimensions and application requirements. Depending on the project, they can be incorporated into new equipment during the design stage or specified for existing machinery where additional safety protection is required.
Whether your project involves industrial machinery, heavy equipment, maintenance access covers, electrical enclosures, vehicle compartments or other applications where operator safety is critical, our engineering team can recommend the most appropriate safety locking solution based on the operating conditions and installation geometry.
What Is a Gas Spring Locking Tube?
A gas spring locking tube is a mechanical safety device installed around the body of a gas spring. Under normal operating conditions, the gas spring functions as usual, allowing smooth opening and closing of the application. When maintenance, servicing or inspection is required, the locking tube can be positioned to provide mechanical support, helping prevent the application from closing unexpectedly.
Also known as a safety locking shroud, gas strut locking tube or gas strut safety locking shroud, this product provides an additional level of protection that is independent of the internal gas pressure. Even if the gas spring experiences pressure loss or mechanical failure, the locking tube continues to function as a physical safety device, reducing the risk of accidental closure.
Because they operate independently of the gas spring itself, locking tubes are widely used in applications where personnel regularly work beneath raised lids, access covers, service doors or heavy machine guards. Their simple mechanical design, ease of use and dependable operation make them an effective solution for improving workplace safety without increasing system complexity.
How Do Gas Spring Locking Tubes & Safety Locking Shrouds Work?
A gas spring locking tube is designed to provide a simple but highly effective mechanical safety function. Because the locking function is completely mechanical, it does not depend on the internal gas pressure or sealing performance of the gas spring.
Normal Operation
The gas spring continues to support the movement of the lid, cover or access panel exactly as intended. The locking tube remains inactive and does not interfere with the normal extension or compression of the gas spring.
Engaging the Locking Tube
Whenever maintenance, servicing or inspection work is required, the locking tube can be manually positioned over the piston rod, ready to provide mechanical support.
Mechanical Protection Provided
Once engaged, it forms a solid mechanical support between the cylinder and the piston rod, helping prevent unexpected closing if the gas spring loses pressure or experiences mechanical failure.
Also referred to as a safety locking shroud, gas strut locking tube or gas strut safety locking shroud, this solution provides an additional layer of protection for applications where personnel may need to work beneath raised components. By introducing a positive mechanical stop, the locking tube helps improve workplace safety while remaining quick and easy to operate.
Simple, Reliable and Independent Mechanical Protection
Unlike hydraulic or electronic safety systems, a gas spring locking tube operates entirely through its mechanical design. No electrical power, hydraulic pressure or additional control system is required. This simplicity contributes to reliable operation, straightforward installation and minimal maintenance throughout the product’s service life.
Because the locking tube functions independently of the gas spring itself, it continues to provide mechanical protection even if the gas spring no longer delivers its original extension force. For this reason, gas spring locking tubes are widely specified for equipment where operator safety is a critical design consideration.
Gas Spring Alone vs. Gas Spring with a Locking Tube
A conventional gas spring is designed to support movement by providing a controlled lifting force. However, if the gas spring loses pressure or becomes damaged while the application is open, the supported component may no longer remain safely in position. A gas spring locking tube adds an independent mechanical safeguard that helps reduce this risk.
| Gas Spring Only | Gas Spring with Locking Tube |
|---|---|
| Provides controlled lifting and counterbalancing. | Provides lifting assistance together with independent mechanical protection. |
| Relies on internal gas pressure. | Mechanical locking function operates independently of gas pressure. |
| No additional mechanical support during maintenance. | Helps prevent accidental closure while servicing or inspection is carried out. |
| Suitable for general lifting applications. | Recommended where operator safety is a key design requirement. |
Why Use a Gas Spring Locking Tube?
A gas spring locking tube provides an additional level of mechanical protection in applications where operator safety cannot depend solely on the performance of a gas spring. Although our Gas Springs Manufacturer | Standart Gas Springs are designed for reliable lifting and counterbalancing, many industries require an independent safety device to minimise the risk of unexpected closure during maintenance, servicing or inspection.
Also referred to as a safety locking shroud, gas strut locking tube or gas strut safety locking shroud, this solution acts as a secondary mechanical safeguard. By providing physical support between the cylinder and the piston rod, the locking tube helps protect personnel working beneath raised covers, machine guards and access panels.
Unlike safety systems that rely on electrical or hydraulic components, a gas spring locking tube operates entirely through its mechanical design. This makes it a dependable solution for industrial environments where simplicity, reliability and ease of use are essential.
