Garage Doors Poole: Drive Mechanisms
The quietest, and by that account, costliest drive options, the belt drive’s Kevlar polymer body is molded into nubby teeth on one side. These rotate through a gear on the operator top to pull the trolley.
The cheapest, oldest, and loudest technology, the bike-chain style chain sits slightly slack when the door is open—at least 2cm above the bottom of the T-rail. The chain makes a racket, but maybe that’s a good thing if someones trying to break in or sneak out.
A continuous threaded shaft connects the operator to the trolley, and its arm reaches for the door. Its threads require biannual lubrication with silicone, and it wears out the trolley more quickly than the other options. This is the middle option for price and noise level.
