Machinery Breakdown Prevention

Failure mechanisms

Machinery breakdown losses rarely have a single cause; they usually result from a combination of factors: inadequate or contaminated lubrication, overload beyond design limits, ingress of foreign objects, resonant vibration, and errors during commissioning or operation after maintenance. Design or material defects often only surface after extended operation, once fatigue cracks reach a critical size.

Preventive measures

Sound design to recognised engineering standards, professional installation with documented alignment and fastening, and protective devices against overspeed, overload and foreign object ingress form the first line of defence. Operating instructions, training of operating personnel and a structured release procedure after maintenance work further ensure that a machine is not returned to service with impermissible operating parameters.

Insurance relevance

For machinery insurance, documentation of design basis, commissioning and recurring checks is a key element of risk assessment, since many breakdown losses trace back to identifiable, previously avoidable causes. Repeated failures of the same machine or the absence of root-cause analysis after a prior loss are treated as a clear warning sign.
