QUESTIONS & ANSWERS
The KUNZ 235.0000 Brake Spring Tester allows operators to test springs in two modes: spring compression height and spring load. This dual capability ensures that technicians can verify compliance with CMM specifications and evaluate spring performance under real-world conditions.
Up to 99 spring programs can be created and stored in the tester’s memory. Each program can include up to three different compression heights or spring loads, making it easy to customize tests for multiple brake spring types used across commercial and military fleets.
The tester is equipped with an automatic alarm system that alerts operators if a spring falls outside the programmed tolerance limits. This safeguard helps ensure only compliant springs are installed, protecting aircraft braking systems from performance issues.
No, the unit is fully self-contained and does not require a computer or external device for normal operation. Test results can be managed directly through the integrated 7” touchscreen display and downloaded via the built-in USB port.
Yes, the tester operates in dead-man control mode, requiring two buttons to be pressed simultaneously to activate the compression system. In addition, a transparent safety curtain protects the operator from potential spring fragments if a spring fails during testing.
Calibration is performed in accordance with DIN EN ISO 17025 standards. This ensures high accuracy, traceability, and compliance with international aviation maintenance requirements.
Yes, special adapters are available to accommodate various spring diameters. Operators should provide the inner diameter of their springs when requesting a quote to ensure the correct adapters are included with the tester.
Yes, all test results are stored internally and can be easily downloaded through the USB port. This makes it simple to maintain documentation for regulatory compliance and maintenance records.
The 7” touchscreen display allows fast program selection, easy setup of new spring profiles, and clear visualization of test progress. This user-friendly interface reduces setup time and helps prevent operator errors.
