[Tweet](https://twitter.com/share) ![CIMG0351](https://blog.weberknapp.com/hs-fs/hubfs/CIMG0351.jpg?width=2304&height=1728&name=CIMG0351.jpg) Whether you’re designing a kitchen appliance, a bar countertop, or ergonomic office furniture, incorporating the right motion control mechanism lends functionality, safety, and elegance to your product. While most people assume **motion control** means electric-powered, there’s still a need for good old-fashioned mechanical engineering in heavy-duty applications. That doesn’t mean your human-powered options are limited – mechanical hardware engineers have been busy for years reimagining the classic hinge to **creatively meet the requirements of specific projects**.   ## Improving on the Classic Hinge Design Because every project is different, a number of **heavy-duty hinge solutions** exist to meet motion control demands. Solutions vary based on a product engineer’s desired torque – [the amount of force required to rotate an object on an axis or pivot point](https://www.physics.uoguelph.ca/torque-and-rotational-motion-tutorial) – characteristics. In hinge terms, torque is the force required to open or close a door, lid, or panel. Here we'll lay out some hard-working options and discuss application-specific projects based on hinge types, including: - Counterbalance hinges - Lift gate assistants (a subset of counterbalance hinges) - Spring-assisted hinges  - Concealed hinges   ### Counterbalance Hinges  Using springs, weights, and levers, counterbalance hinges balance the weight of heavy panels and lids against gravity’s downward forces, reducing the amount of force required to lift and move them.  These hinges give users precise control for opening and closing – including the ability to stop and stay in place – improving a piece’s functionality and safety. Depending on the motion needed, there are many applications for counterbalance hinges:  - Medical centrifuges - Slide-preparation devices - Industrial equipment - Hatches for submarines and armored vehicles - Boats & barges - Grain silos - Grills - **Vacuum chambers**   #### ![vacuum hinge](https://blog.weberknapp.com/hs-fs/hubfs/vacuum%20hinge.png?width=250&height=375&name=vacuum%20hinge.png)Featured Application: Vacuum Chambers Used in many industries and scientific research projects, [vacuum chambers](https://www.weberknapp.com/case-studies/case-study-vacuum-chamber-requires-safety-upgrade/?utm_referrer=https%3A%2F%2Fwww.weberknapp.com%2F) provide an effective way to carry out experiments or processes that require an environment free from contamination. These industrial-sized airtight enclosures are large and heavy, as are their lids. Often they’re outfitted with gas springs, which are prone to failure. Counterbalance hinge technology offers a better solution for **a safer, more reliable opening and closing experience**. [![motion control design guide](https://no-cache.hubspot.com/cta/default/5515947/852c9dc9-23b1-4ad3-8c09-9c58924abd77.png)](https://cta-redirect.hubspot.com/cta/redirect/5515947/852c9dc9-23b1-4ad3-8c09-9c58924abd77)   ### Lift Gate Assistants  A lift gate assistant hinge is uniquely counterbalanced to provide a user-friendly open/close feature to easily lift a heavy object and confidently interact with it knowing it won’t fall down. A subset of the counterbalance hinge variety, lift gate assistant hinges and similar style hinges are **designed for hospitality** -- bars, restaurants, hotels – for a number of furniture solutions, including:  - Murphy beds - Countertop pass-throughs - Fold-down tables and seating for RVs or campers - **Pass-through bars**   #### Featured Application: Pass-Through Bars Adding a hinged bar or countertop helps make use of valuable serving and food prep space while improving traffic flow. Restaurant designers have turned to a number of options to achieve the motion of lifting a bar or countertop to a vertical position, such as pistons and spring hinges. [Lift gate assistant mechanisms](https://www.weberknapp.com/case-studies/case-study-lift-gate-assistant-for-restaurant-design/?utm_referrer=https%3A%2F%2Fwww.weberknapp.com%2F) are designed to handle the movement of heavier objects safely  and with ease, so they’re perfect for allowing wait staff, for instance, to lift a large countertop without fear of it dropping back down, and to also safely and easily lower it back into place. [![Lift gate assistant lid calculator](https://no-cache.hubspot.com/cta/default/5515947/7364b9ec-c5df-4e03-b4ed-fb27437d095d.png)](https://cta-redirect.hubspot.com/cta/redirect/5515947/7364b9ec-c5df-4e03-b4ed-fb27437d095d)   ### Spring-Assist Hinges Spring-assist hinges harness stored energy in springs. The springs provide assistance when opening or closing doors and lids, making it much **easier to open** them with **minimal effort**. Their torque can also be adjusted based on preference. Spring-assist hinges tend to **cost less** than their counterbalance cousins because they have fewer components. They can be ideal for outdoor applications, as well as use in extreme temperatures. Some applications include:  - Grills - Cabinetry - Cryogenic Freezers - Tanning Beds - **Drum smokers**   #### Featured Application: Drum Smokers ![smoker with camper](https://blog.weberknapp.com/hs-fs/hubfs/smoker%20with%20camper.png?width=250&height=242&name=smoker%20with%20camper.png)Cooking appliances, especially outdoor [drum smokers](https://www.weberknapp.com/weber-knapp-drum-smoker/drum-smoker-accessories/), benefit greatly from spring-assisted hinges. They allow users to keep their hands free while checking on a smoke because they **open beyond 90°** to allow full access to the drum’s grate, which is especially important as a drum smoker is hot. Likewise[, a spring-assist hinge can reliably perform in extreme heat over and over again](https://blog.weberknapp.com/smokinuglyblog/heavy-duty-grill-hinge-options-good-better-best), partly due to its simpler design.

Unlike traditional surface-mounted hinges, concealed hinges are hidden from view when a door is closed, creating a sleek appearance. Hidden hinge design is a common feature of interior and security doors, since they’re sturdy and  prevent outside access to the hinge itself. They’re also used more commonly now in premium appliances, most notably in:  - Freezers - Wine coolers - Cabinetry - **Hidden fridges**   #### Featured Application: Hidden Hinge Fridges As kitchens have increasingly become hubs for family life, **high-end appliance designers are turning more to concealed hinges to develop pieces that blend seamlessly with surrounding cabinetry**, especially [hidden hinge fridges.](https://www.weberknapp.com/case-studies/case-study-concealed-hinges-for-the-hidden-fridge/) While designing a heavy-duty concealed hinge sturdy enough to support a food-laden refrigerator door is a challenge, it isn’t impossible, and the results are stunning. The best concealed hinges have soft-opening and self-closing features to elevate the user experience. [![Learn about our SI.1 Hinge! ](https://no-cache.hubspot.com/cta/default/5515947/eba323fe-39f0-43ee-882b-6593a5862842.png)](https://cta-redirect.hubspot.com/cta/redirect/5515947/eba323fe-39f0-43ee-882b-6593a5862842)   ## Choosing the Right Motion Control Option From counterbalance hinges to lift gate assistants, spring-assisted hinges, and concealed hinges, the right motion control option makes a huge difference in any project. By understanding the advantages of different types of hardware solutions for your demands, you'll be able to choose the best one for your application.  ### Keep Your Project Moving We love helping teams find innovative solutions to their motion control challenges.
