Garage Door Torsion Spring Lift Cables - As a door expert witness, I'm called upon many times a year to evaluate garage door injuries. Garage doors come in several shapes and sizes. Their functions range from basic security of an area to concealment that is cosmetic. Most doors can be broken down into a few basic styles or classes. Typical modern garage doors for residential uses are usually predominantly of the overhead sectional variety. That style of the door comes in several shapes, substances, levels of insulation, along with an extensive selection of appearance possibilities.
They are accessible as a prefabricated kit or built as a custom layout to complement the decor of any building. Higher security requirements are generally dictated by commercial warehouse type installations. A great choice with this security kind of door is the "roll up" design that resembles a roll top desk kind of door. This door may be made with many different substances that can be as robust as the abutting walls, making forced entry by means of this opening very difficult.
Before, the largest concern with managing an overhead garage door was the possible dangers related to the springs taken for balancing the door weight. Pre mid-1960's garage door installations commonly relied upon a pair of stretched (tensioned) springs to help the operation of the garage door pivoting hinges. These springs became loaded (tensioned) as the door was transferred to the closed position.
Some of the most dangerous aspects of the spring systems was that after a time frame, often without any care or inspection, the points of attachment of the springs would corrode or become weak. This weakening of points or the springs of attachment would often result in an inadvertent explosive failure fling the spring that is broken components around the garage, embed the spring or steel components to the garage walls, other things in the course of traveling or automobiles.
