Garage door springs counterbalance the weight of the door to make it easy to open and close. They serve the same purpose of counter weights used to balance doors in centuries past and in many doors today. For example, if a garage door weighs 100 pounds, a spring force of 100 pounds needs to pull against the weight of the door. This can be accomplished with springs that either stretch or torque special parts to assist in balancing the door.
Standard residential torsion springs are found on a shaft above the center of the garage door. These springs typically come in 1 3/4", 2" and 2 1/4" inside diameters.
If your garage door has a broken EZ Set spring, you have two basic options for restoring your door to its previous working order. The simpler and safer option is to keep your EZ-Set system. The other is to convert to the Standard Torsion Spring system.
Wayne Dalton's TorqueMaster spring system uses unique hardware. The track radius is smaller than on most other doors, the cable drums are smaller, and the shaft has a unique shape. The torsion springs, instead of sliding over the shaft, fit inside the shaft.
Extension springs have four characteristics: length, inside diameter, wire size, and type of end. Even though springs have these properties, manufacturers generally do not make their extension springs based on the dimensions you may find on your door. Every manufacturer has its own design for making springs.
There are two main styles of one-piece springs. The first is the standard spring. This spring is used by a variety of door manufacturers. If the top of your door has rollers that move along a metal track that extends horizontally toward the back of your garage, you have standard one-piece springs.
Commercial and industrial overhead doors range from weighing a few hundred pounds to over a thousand pounds. Vertical-lift and high-lift door systems are frequently used in commercial and industrial settings to maximize space. Read below measure your old spring(s) and find your new torsion springs to purchase.
One-piece curtain doors operate in a similar manner to steel-rolling door springs. Like a steel rolling door, the curtain on these doors wraps around itself as the door opens. The primary difference, however, is that steel rolling doors are made of interlocking slats, while one-piece curtain doors are just one piece of steel. While steel rolling doors are typically found in heavier commercial and industrial environments, one-piece curtain doors are common in self-storage facilities.
The torsion springs on steel rolling doors work the same way as other torsion springs in the garage door industry. When the door is closed, the spring is wound. The spring is secured to a spring anchor bracket on one end and to the shaft on the other. When the steel rolling door opens, the spring in the barrel supports most of the door weight. The remainder of this weight is lifted by the chain hoist or the operator.
Measuring garage door torsion springs is precise, technical work. It often stumps experienced machinists, engineers, and garage door service technicians. In the door business, we often make mistakes ordering springs. The standard joke is that we'll use them as boat anchors, but you may not have a boat! Click to learn how to avoid ordering a boat anchor.
Often we have to start from scratch and re-engineer the torsion springs for an existing garage door. We do this by weighing the door and providing the drum information, door height, and track radius.
There are two ways to weigh a garage door. If you have winding bars and torsion springs on your garage door, you'll find this video helpful.
If you have extension springs on your door, or if you don't have winding rods for a torsion spring door, you'll find these instructions helpful.
The main reason is to maximize cycle life. Unmatched springs will usually have one with a shorter cycle life that will break first. If both springs are replaced at the same time, the remaining cycles in the unbroken spring will go unused.

The first step in learning how to service dock levers is understanding how they work. Learn the function of components common to all dock levelers whether Mechanical, Hydraulic, or Pneumatic.
The first step in learning how to service dock levers is understanding how they work. In this video we'll cover the primary operating mechanisms used by dock levelers. This includes both the general design as well as the specific lifting mechanisms which fall into three categories: Mechanical, Hydraulic, and Pneumatic.
The following safety instructions are intended to help provide proper safety guidelines for working on any dock leveler. Like any mechanical piece of equipment, if the proper precautions aren't taken, serious injuries or death may occur.
Most mechanical dock levelers use snubber mechanisms to lift the lips as they are raised, and they close slowly as shocks absorb the weight of the lip. In many of the Kelley dock levelers, however, a push bar and a yieldable rod are connected to a link assembly so that when the deck is raised the push bar drops down. Then, as someone walks across to the outside of the dock leveler, the plate on the push bar catches on the middle bolt allowing the push bar to raise the lip..
In most Rite-Hite dock levelers, a ring rolls in the curve of a lip keeper as someone walks across the deck of the dock leveler. This allows the lip assist bar attached to the ring to push the lip up. Over time, the bar connecting the ring and the lip assist bar wears out, and the ring is unable to stay on the track of the lip keeper.This indirectly prevents the lip from raising when someone pulls the pull chain. This tutorial demonstrates how to properly replace a worn lip assist bar in a Rite-Hite dock leveler.
In most Kelley dock levelers, a hold down housing stores a ratchet bar that locks to the bottom of the deck and keeps it closed. As someone pulls the release chain on the deck, the ratchet bar unlocks and extends, allowing the dock leveler to open.
