How often should my garage door be serviced?
The selection of the hardware to be used for any particular installation begins with accurately determining the size and mass of the door, but that is not all that is required. The application of the door, i.e. the duty cycle it will be required to perform and the environment in which it will be operating are equally important. For normal domestic applications, a duty rating of 2 000 cycles per year is used. This equates to approximately 5 cycles per day. The design 'life expectancy" of components such as springs, liftings, cables, rollers, cable drums and bearings is 10 000 cycles for domestic doors, which equates to 5 years of usage. After that period, they need to be replaced!
When doors have to endure a higher traffic density of say 50 - 60 cycles per day, (or approx 20 000 cycles per year), then every component making up the door must be designed, constructed and selected accordingly to suit the application.
Again... there are no short-cuts!
