The coin test

Halit Sisman modestly describes himself as focused and experienced, but if there is an issue when an elevator is first put into operation, the team calls for ‘le docteur.’ That’s what they call Sisman, since he can always diagnose the problem. His colleagues say he has a sixth sense when it comes to elevators.

Quality is key

The 42-year-old Schindler engineer with the cool nickname is called in right at the end, once the mechanical and electrical work has been completed and before the elevator is put into operation. He spends one or two days performing final tests and takes care of the fine-tuning. ‘It is always a special moment when you take the first ride in a newly installed elevator,’ says Sisman – even after seven years at Schindler.  

During the elevator’s ‘maiden journey,’ Turkish employees who work for Schindler perform a special test to check the quality of the work: They balance a coin on its edge on the rounded smooth handrail of the elevator. The coin shouldn’t move when the elevator begins operating, continues its journey and then stops. This test doesn’t allow for even the smallest jolt. Halit Sisman has a 100% success rate.
