In contrast to an overhead type of garage door, be it sectional or single panel, roll up doors have a totally different type of operating system. When these doors are used, they can be concealed in an overhead or under mounted trough. These doors operate similarly to a roll top desk door except for how they are stored when not in the closed position. They normally coil as they are retracted, and require significant gear trains to reduce the effort required to move these doors up and down into position. Often the forces needed to move these roll up doors require a reduction type of transmission that allows a very heavy door to be operated effortlessly.
Your roller garage door comes with a remote to automatically open and close it. When you are approaching the garage door, you simply press the button on your remote, and the door opens by the time you reach the garage. Then, you drive in, press the button again and the door automatically closes. The Genie garage door opener utilizes their Intellicode software that changes the passcode that is transmitted from their garage remote to the garage to open it. You never have to worry about some electronically stealing your passcode, copying it, and opening it without your persission.
With a torsion type of spring, the energy is imparted or removed by rotating the spring clockwise or counter clockwise depending upon the direction of usage. With professional installation, the complete loading of the torsion spring is controlled by the garage installer, and is determined by the weight and size of the garage door that it is operating. When this type of torsion spring fails, it remains attached and intact to the location on the horizontal control rod where it was mounted. I have not heard of or seen any torsion spring fly across a garage, creating injury from failed components as with the stretched older style garage door springs. This is not to say that injuries have not occurred with the torsion style spring. The installation of this type of spring is generally safe when left to a trained garage door installation professional. Severe and serious injuries have occurred when untrained, unqualified individuals have attempted to install or service this type of spring.
I have been involved in numerous garage door lawsuits where many different reasons for an injury have occurred. Having been retained as expert witness for both plaintiff and defense, several common factors have been observed. In many cases, unqualified individuals have attempted to repair or install garage doors. They have lacked the knowledge, skills or even the basic required tools to perform the work safely and properly. I have been hired as an expert by garage door manufacturers and installers to defend claims that they are not responsible for alleged product defects. In most cases, the components that failed, failed as a result of abuse or improper installation on the part of the end user. As stated above, the installation of many garage doors is not appropriate for an untrained person.
