System and method for repairing a counterbalance spring in an overhead rolling door assembly

摘要

A system and method for supporting and rotating an axle of an overhead rolling door assembly while replacing a counterbalance spring. A support stand is provided. The support stand is positioned under the overhead door assembly. The overhead door assembly is disassembled enough to expose its main axle. The support stand is adjusted in height to engage the main axle so that the support stand holds the main axle at an elevated position. The broken counterbalance spring is replaced. The main axle is the reinstalled into the overhead door assembly. A pulley wheel is then attached to the main axle. The pulley wheel is turned by winding a cable around the pulley wheel and then unwinding the cable with a winch. This rotates the main axle with the torque needed to properly pre-tension the replacement spring.
