Types of Garage Door Openers
Types of Garage Door Openers
For many years, homeowners who wanted automated garage doors had three options: chain, belt, or screw-driven openers. With the development of residential jackshaft and direct-drive vehicles, garage doors have evolved. In this article, LMS Garage Doors in Sacramento explore the types of garage door openers.
Standard Garage Door Openers
- Chain-Driven Garage Openers – Similar to a bicycle chain, pushes or pulling motion that connects to a metal bar called a J-arm that is attached to the garage door. If your garage is located beneath a bedroom, the noise caused by metal-to-metal contact and vibration may be bothersome. If the garage is unattached, it is most likely not. Newer chain-driven devices with DC motors and soft start-and-stop technology are much quieter than older models.
- Belt-Driven Garage Openers – These are identical to chain-driven ones in design, except that a strengthened belt pushes or pulls the trolley. Fiberglass, polyurethane, or steel-reinforced rubber can be used to make the belts. Belt-driven openers are equally dependable as chain-driven openers, but they are quieter. The disadvantage of belt-driven openers is that they are around $30 to $60 more expensive than chain-driven devices.
- Screw-Driven Garage Openers – The trolley rides on a threaded-steel rod as a motor rotates the rod in screw-driven openers. Manufacturers argue that because this design has fewer moving parts, it requires less maintenance than other systems. screw-driven openers, on the other hand, have had problems in areas with huge temperature fluctuations from summer to winter. They are also noisier than belt-driven openers. However, producers of screw-driven openers have lately improved their temperature sensitivity and noise levels. screw-driven openers are also among the fastest these days, opening a door at 10- to 12-in. per second as opposed to the conventional 6- to 8-in. per second. (All garage door openers close doors 7-in. per second for safety.)
Garage Door Openers with Jackshaft and Direct-Drive
- Jashift Openers – Unlike the other systems, jackshaft openers are mounted on the wall beside the garage door. A 24-volt direct current motor powers the pulleys and cables that turn the torsion bar and lift the garage door. When the motor is reversed, the cable tension is released, allowing the door to lower. This system is both dependable and quiet. Furthermore, it maintains the ceiling clear for overhead storage and is appropriate for garages with high or low ceilings. Many other garage door openers are more expensive than jackshaft openers.
- Direct-drive units – Because there is just one moving part—the motor—direct-drive devices are said to be the quietest of all garage door units. The motor was developed and built-in Germany and traveled along a fixed chain embedded in an overhead rail. The moving motor is connected to the door by a J-arm. Direct-drive machines are roughly the same price as belt-driven machines and have lifetime warranties.
DC-Powered Garage Door Openers
DC motors are more efficient, quieter, faster, smaller, lighter, and lighter than AC motors. Many have variable speeds, allowing for soft-start and soft-stop technologies. They can also be outfitted with backup battery systems. The battery in later versions is incorporated with the opener motor casing. When the power goes out, your garage door openers will keep working for up to two days, depending on how frequently you open and close the door. Battery backup will also ensure that other services, such as garage lighting, security, and safety alarms, continue to operate. Brushed DC motors do not have the same lifespan as AC motors, whereas brushless DC motors do.
