Now she knows that something isnt right. As she stands there rubbing her eyes trying to make sense of what was happening a man suddenly emerges from her family room looking at one of her familys DVD covers. At that point the wife begins screaming for her husband "Someone is in the house! Get up! Get up! When the husband ran out of the bedroom he saw the criminal sprinting across the house to the front door. It just so happens that there was a child safety lock on the front door so the home invader stood there struggling with the front door long enough for the husband to retrieve his rifle and grab the man. The police soon came as they held the robber at bay and an arrest was made. It turns out that this burglar was part of a group who had been invading homes in the area.
In response to the inherently dangerous old style garage spring issues as above a newer and safer system for opening the overhead garage door was created. The idea was to transfer the load or weight of the door via a cable and pulley system to a vertical rod now equipped with a torsion (twisted) spring. This type of spring is installed with specialty hardware and bolts to a fixed plate at one end while the entire spring is installed around a horizontal pipe. This load balancing device is normally installed directly over the header of the garage opening. Using appropriate cables connectors and pulleys the weight of the garage door is transferred into the torsion spring system. The difference between the old style stretched spring and the newer torsion spring is the way that the spring energy is stored. With the old style stretched spring the energy is stored and released by pulling on the spring or returning the spring to its un-stretched condition.
What can we learn from this real life crime that occurred in Dallas Tx? Well the first question we need to examine is how the burglar got into the home. It all boils down to garage door security. The family had parked their car outside of their home rather than inside the garage. This gang of burglars evidently would cruise neighborhoods looking for cars parked outside of the garage. Then as in the case with this attempted robbery they would simply break the window of the car and grab the garage door opener. That gave them an easy way to directly enter the house.
These doors can be chain driven either manually or can be automated using electric motors. Roll up doors require more frequent evaluation and servicing than a standard overhead garage door. The tracks that are mounted vertically on both sides of the garage opening need maintenance and cleaning more frequently and are often blocked by foreign obstructions or damaged by collision of some type. These roll up doors are often held open by some type of ratcheting action. Proper balancing of these doors is often more important than an overhead type of door as the weight of these type of doors is normally much greater than an overhead door.
