Hanover Doors has long seen a need for a lift system that would work well on extremely wide, high, or frequent use applications. As well where caustic humidity is a challenge. In short, where frequent service is not an acceptable option. With these challenges in mind, we refined a system that has the right qualities to solve most of these issues and problems, but allowing you to use your own door panels, cable, and seals. We provide you with the lift mechanism, end caps to fit your panels, an installation manual and video. Complete door systems are available if you so desire.

The weight counterbalance concept was developed more than 50 years ago by Abram Reimer in the small Mennonite village of Steinbach, Manitoba. Canada and parts of the northern U.S. were the early recipients of these weight counterbalance doors. Grandson, Greg Reimer (part owner of Hanover Doors) has witnessed and helped produce many innovations in this nearly indestructible weight mechanism. The weight counterbalance concept being so good has allowed this type of door to survive in an intensely competitive market boasting thousands of doors still in operation (on the origional weight system for 2 and 3 decades.(some even more) Many of these systems have had little or no service required. Thousands of these systems are being used in remote (hard to reach locations) and many by large trucking firms, warehousers, hutterite colonies, farmers and commercial/industrial businesses. These customers have learned of the quick payback of these incredibly reliable door systems. The savings in service free operation will normally, (in high use situations) pay for the investment in less than 10 years. With most doors (under heavy use) it would now be time to replace or expect a very high cost of operation. Not so with our “Weight Counter Balanced” system. By now, you have spent little or nothing at all on service or maintenance and your doors should still be good for another 20 or more years. The initial investment on smaller doors is usually slightly higher than industry standard torsion spring products and about the same or less in cost on the very large doors. These doors can be as wide as 40′ and practically any height.

This door operating system can and will deliver the most economical long term service of any overhead door system on the market today. In moderate to heavy use application this system should save you the equivalent of the cost of the door within the first 10 years. After that, you may still expect another 20 to 30 years of virtually trouble free and service free operation. With most other overhead door operating systems, it is likely that you would replace the doors and lift systems as often as every 5 to 9 years. Many of Canada’s most successful trucking companies, (remember the harsh climate) have used this exact same system for more than 40 years.


Simple and durable. Steel ballast is used to counter the weight of the door. The door goes up and the weights come down. The door goes down and the weights go up. An enclosure on one side of the door guides a series of weights. These weights are connected to the door by a cable through a series of pulleys. This is the Hanover Lift System.

This system offers many advantages. – It’s durability allows for almost unlimited cycles of operation. Servicing the door is easy but under normal use is usually not required. – It is ideal for very high, wide or high and wide doors.

Unlimited Cycles – Longevity

  • The longevity of the Hanover Lift System is the result of the design of the system as well as the design of all the components. All of the parts used in the Hanover Lift System are designed to last the life of the building into which the system is installed.
  • The sealed rollers for example, have a 2000lb load capacity. The rollers and welded hinges ensure long life regardless of how often you use the door.
  • The weight enclosure is a welded steel cage and for your safety it is covered with 28 gauge galvanized metal to keep out fingers.
  • Severe conditions are characteristic of potato or vegetable storage buildings. The Hanover Lift System will stand up to the extreme humidity and corrosive effects of vegetable storage.


  • The Hanover Lift System works well in most standard or special applications. Hard to reach, hard to service mine shafts or other applications such as apartment block garages, hospital parking or applications that demand hundreds of cycles per day.
  • Grain elevators may require doors up to 28 feet high or higher.
  • Warehouses or service shops that require extra wide and high overhead doors. Sliding mullions are optional and extremely effective in providing a narrow or very wide opening.
  • Many new or existing buildings may have very little headroom. The Hanover Lift System works well with as little as 12″ of headroom.
  • Hanover Lift Systems stand up well in truck and car washes. Quonset buildings with limited headroom, corporate farms and commercial or industrial warehouses.

Simplicity of the Weight System

  • The principle of The Hanover Lift System is as follows. A weight is carried up and down an enclosure. As the weight moves, the door moves. The force of gravity acting on both the door and the weights creates equilibrium. Fewer panels are required, as standard panels must be joined to create panel heights of 42, 45, or 48 inches.The only moving parts are the cables, pulleys and rollers. Endcaps to accommodate your door panels are included.
  • Balance adjustments are made at the time of installation. The balance is so precise that even a very large door can be opened easily by hand.
  • The Hanover Lift System is easy to operate manually, by chain hoist or by an electric operator. Hand transmitters, photo eyes, auto reversing options and all industry standard safety and convenience features are readily available.


  • An essential part of the Hanover Lift System is the face hardware which has been built with the same durability in mind. The lift system and face hardware can be installed on most panels of your choice.

Track Hardware

  • Along with the heavy-duty hardware, Hanover Lift Systems supplies a track and pulley system as an integral part of the Lift System. A Hanover Lift System includes the weight counter-balance, the hardware kit including face hardware, tracks, end caps and pulleys. Everything is included except the panels and seals.

For doors using Weight Counterbalance lift mechanisms

  • All of the roller brackets, intermediate hinges, and the struts should be checked for security. Tighten any loose fasteners and replace any hinges or roller brackets, which appear unreasonably worn in any way.
  • Check all the rollers and if any appear wobbly they should be replaced.
  • Check the fasteners of the vertical tracks and the horizontal track hangers and tighten any loose fasteners.

NOTE: Use Hanover approved lubricants should any of the long life lubricants be replaced. (“Fluid Film” is a suitable lubricant for most items and should be available at your local hardware store.)

NOTE: Weight counterbalance lift mechanisms are maintenance free under normal conditions. Under conditions of severe humidity, older doors with wood frames may require rebalancing. New doors using Richards-Wilcox panels rarely require any attention.
