RAIL TRANSIT SPRING SOLUTIONS
Rail spring programs designed for vibration, duty cycle and service life.
We engineer repeatable components for vibration, repeated use, environmental exposure and maintenance cycles.
INDUSTRY REQUIREMENTS
Duty cycle and maintenance conditions come first.
The design review connects shock, vibration, load, environment and replacement expectations.
Continuous vibration and shock
Review dynamic loads, travel and retention requirements.
Corrosion and outdoor exposure
Match material and finish to weather and service conditions.
Long service intervals
Control repeat-order geometry, force and supporting records.
TYPICAL APPLICATIONS
Door & Access Mechanisms
Return, retention and controlled movement in passenger access systems.
Coupling & Braking Assemblies
High-load and preload functions in mechanical operating assemblies.
Cabin & Electrical Equipment
Compact return and positioning functions in interior equipment.
RECOMMENDED SPRING FAMILIES
Compression Springs
Designed to resist axial compression and deliver reliable performance.
Extension Springs
Built to deliver reliable tension and controlled extension.
Disc Springs
High load capacity in compact assemblies.
Wire Forms
Complex formed-wire parts manufactured to specification.
FROM REQUIREMENT TO RELEASE
Application Review
We review the mechanism, loads, movement, environment and production requirements.
Spring, Material & Prototype
Spring geometry, material and finish are defined before prototype and first-article review.
Controlled Production
Approved tooling, process settings and in-process checks support repeatable output.
Validation & Records
Inspection, performance checks and agreed records are completed before release.
QUALITY EVIDENCE
Load & Dimensional Checks
Working loads and critical geometry are verified to the released drawing.
Cycle Testing by Requirement
Duty-cycle testing can be defined around the operating mechanism.
Material & Batch Documentation
Agreed material and inspection records follow each production lot.
Bring the application. We will define the spring program.
Share your drawing, load, environment, volume and required records.
