Garage Door Spring Replacement

Today, sectional lift gates are becoming more and more common. These constructions are installed in garages in private country plots, car washes and service stations, warehouses, and many other industrial premises. Sectional gates are a solid canvas made of sandwich panels, which move on special guides. When opening the opening, the sash rises vertically, gradually tilts inward, and is drawn parallel to the ceiling slab, which provides a space-saving garage or other premises.

Some of the most important elements of sectional doors are torsion springs. These products make it possible to manually raise and safely lower heavy webs of almost any size. This is achieved by compensating for the weight of the door. During production and installation, the torsion springs are individually selected for the specific door, taking into account the dimensions of the leaf, the type of lifting mechanism, and the degree of use of the barrier system.

When the sectional door is fully closed, the springs are in the most twisted state – in this position, they are “cocked,” experiencing the maximum load. If we take into account that the lift gate is in the closed position almost all the time, the torsion springs are continuously subjected to intensive wear and tear during the entire service life of the construction. Although manufacturers lay down the working life of products, calculated from 25 to 100 thousand cycles of opening-closing, they can burst before the specified period, and to return the barrier to work ability, it is necessary to replace the springs of sectional doors.
