Know how the spring behaves, not just how it looks.

Railway springs are accepted by how they respond under load. Testing turns that response into repeatable evidence for production, overhaul and maintenance.

In practice: put the spring in the machine, load it in a controlled way, and see whether it behaves like the suspension expects.

Characterize railway coil springs under controlled load.

Best for: railway spring production and overhaul

Handle higher-load spring scragging and chasse workflows.

Best for: heavy railway spring programs

Test leaf springs in compression and bending.

Best for: railway leaf-spring maintenance and production

Configurable spring-rater platform for springs, coil-overs and elastomers.

Best for: general component labs and flexible test work

Motorized loading, recipes, data capture and pass/fail workflows.

Best for: repeatable production or overhaul quality control

Use the correct fixture and orientation.

Load, unload or cycle it as the procedure requires.

Capture the spring’s actual response.

Compare the result to the controlled requirement.

The function is defined by load versus movement, not external appearance.

Before: the spring looks serviceable.

After: its actual mechanical characteristic has been measured.

CBP separates railway-specific qualification from general component testing, then routes the requirement to Easydur or CTW without pretending the platforms are interchangeable.
