An elevator stops working one day, passengers get trapped, and everyone assumes that the failure occurred without warning.

Before a serious illness develops, the body often gives warning signals such as fever, fatigue, pain, excessive sweating, or weakness. Timely diagnosis and treatment can prevent a minor problem from becoming a major one.

Abnormal noise, vibration, temperature rise, rope wear, door irregularities, and control system issues are often early indicators of future failures.
Recognizing these warning signs can save thousands—or even lakhs—of rupees in repair costs and prevent prolonged shutdowns.
A traction machine normally operates with predictable noise levels and temperature.
When any of the following conditions appear, they should be treated as warning signals:
Possible causes include:
