High Speed Dual-Door Latch Test System

Puritan has designed and built several test systems for testing door latches. The machine shown provides two simulated door masses that carry the latch assembly being tested.

The machine tooling operates the internal and external latch levers and lift-pulls, as well as the articulation of the doors.

Latch velocity and rate-of-change of velocity are measured by accelerometers mounted on the simulated doors. All latch levers are also equipped with load cells and torque transducers where necessary.
