The "liability" angle: The flip side of "safety issue" is "liability". This is not used to directly sell you something; it is used to demean the cheaper alternative and prod you into buying a more expensive (and profitable) option. For example, you may be pressured into buying a whole new door, when you just need a new spring, by the salesman telling you he can't just replace the spring due to "liability" issues. Since product liability is a big burden on the garage door industry, and so many old doors (and especially automatic openers) are dangerous, this may be a genuine reason to accept a higher price.
Spring index lower limit: DASMA standard 102-2004 provides a lower limit of 6 for the spring index, which is symbol C in our formulas above (section 9.3). Other interesting items in this standard include an upper limit for how much the door sags when raised (no more than 1/120 of its width, section 9.2.1), that each of the two bottom brackets should sustain twice the door assembly's weight (section 9.2.2) for a total safety factor of about 4, and that the lift cables should provide a safety factor of 5.
Electric Garage Door Openers – Service and repair of the electric garage door opener itself, including the lift mechanism that pulls the door up and guides it down. This is typically not part of the garage door itself and is serviced and repaired on its own interval. Typical service includes inspection, repair, adjustment, and lubrication if needed. Also, we typically inspect the mounting of the unit as well as its attachment to the door itself.
To estimate the maximum physical force required to wind these springs, consider that they are balancing the weight of the door with a torque applied to a lift drum on each end of the torsion shaft. The lift drums have a 2-inch radius, which is the standard residential size, and corresponds conveniently to about a 1-foot circumference. If we pessimistically assume the 10-by-7-foot door has a weight of 350 pounds, this implies a torque of 350 pounds on a 2-inch radius, that is, 700 inch-pounds, or 58 foot-pounds. Each of the two springs should be exerting slightly less than half of the balancing torque, or 29 foot-pounds. Compare this to, say, the bolts in an automobile, which are typically torqued to values of about 50 foot-pounds, or tire lug nuts, which may be torqued to well over 100 foot-pounds.
Because your garage door is a major entryway to your home, it is important to keep it in good working order for your own safety, security, and convenience. Choosing the right style and appropriate materials will lessen the amount of repairs that may arise. Additionally, investing in regular maintenance can be cost-effective in the long run. If your garage door is in need of major repair, it is best to call a professional garage door repair company for assistance. Typically, the company will charge for at least one hour for making a service call. However, the benefits of a professional repair job can well outweigh any costs, as a professional can ensure the safety, security, and proper operation of your garage door.
And for some extra features, you'll appreciate accessing the system through the MyQ smartphone app. You can set up this Chamberlain opener to automatically close the door after 1, 5, or 10 minutes, which is great for people who are a bit forgetful. We also really like the motion-detecting control panel, which turns on lights whenever it records nearby movement.
