Repair Garage Door Springs and Cables in Fort Lauderdale

CALL Garage Door Fort Lauderdale LLC FOR SAME DAY SERVICE

The garage door spring – not the opener – is what allows a 200-pound or more garage door to be lifted with ease. Springs counterbalance the weight of the garage door, allowing the opener to easily glide the door open and shut. If you were to lift your door by hand, it should feel like it weighs only a few pounds.

If the garage door won’t stay where you release it or seems to weigh more than 5 pounds, then your spring is showing signs of age and may be about to break. The heavier your door feels, the more likely it is that your spring is deteriorated.

TYPES OF SPRINGS

There are two types of springs for garage doors – torsion springs and extension springs. Torsion springs work by torsion, or twisting. They store mechanical energy when twisted. We use special instruments to wind the coils of the spring, which then applies torque to the center shaft, a metal tube located directly above the center of the garage door. At each end of the center shaft is a set of cable drums. Cables on the drums attach to the bottom bracket of the garage door. As the center shaft spins, cables wind and unwind on the cable drum to lift and lower the door. Extension springs stretch above and parallel to the horizontal tracks for the garage door.

Extension springs are also attached to cables that are anchored to the bottom bracket of the garage door. Instead of winding as a torsion spring does, these springs apply resistive force as the spring stretches. Springs extend as the door closes, storing mechanical energy used to open the door. Each spring along the tracks work independently of each other to balance the weight of the garage door. If the two springs become unbalanced, the door will open unevenly or wobble and cause destructive wear and tear on the other moving parts.
