Vectis® Spring-Assist Hinges | Motion Control Engineering

Like a 3d jigsaw puzzle, selecting a heavy-duty hinge that works for your application can get overwhelming. You have to consider the environment the hinge will live in, its lifespan, and its cost.  

But there are hinge options that balance all three to provide a reliable and cost-effective hinge solution: the Vectis® spring-assist hinge lineup by Weber Knapp.

Fueled by industry-leading Vectis® technology, our spring-assist hinge has not only been tested through 15,000 cycles at the max hinge setting but is also adjustable between the upper and lower torque limits. Made up of a fully mechanical mechanism, spring-assist hinges provide lift assistance with adjustable torque settings to have an open or closed bias.  Vectis® spring assist hinges provide a premium, long-lasting motion control solution.

Vectis® Technology Spring-Assist Hinge

Ever wonder how cryogenic freezers, tanning beds, and other heavy-duty lids open safely despite weighing 50 to 100+ lbs.? The answer: spring-assisted or spring-loaded hinges.

Vectis® spring-assist hinges are designed and fitted with industrial-grade springs that exert force between the load and the hinge, providing exceptional lift assistance. And each spring-assist hinge can have its torque adjusted during manufacturing to fit specific weight-bearing requirements. 

Whether you’re designing a grill lid, a flip-up bar, a countertop, or even a hatch for an armored military vehicle, the Vectis® spring-assist hinge provides a safer, more cost-effective alternative to standard or gas hinges.

Vectis® Technology: Spring-Assist vs. Other Hinges

Vectis® Technology is the culmination of 100+ years of mechanical motion control engineering research to quite literally support the high-stress environments of dozens of applications. Whether your spring-assist hinge is located in a kiln, cryogenic freezer, or food processing countertop, the power of spring-loaded hinges increases your efficiency and safety. While there’s an abundance of hinges on the market today, spring-assist hinges provide a weight-mitigation solution that other types of hinges can’t:

Spring-Assist Hinges vs. Counterbalances & Gas Springs

Compared to counterbalance hinges, spring-assisted hinges:

  • Can handle heavier load applications for their comparative size
  • Are easier to maintain, unlike counterbalances that may need field adjustments
  • Have no additional friction components
  • Typically cost less because they have fewer components

Compared to gas springs, spring-assisted hinges:

  • Are less expensive to operate and replace
  • Thrive in extreme temperature conditions and won’t explode in the event of a failure
  • Allow a greater degree of design customization and fine-tuning

Weber Knapp’s proprietary Vectis® spring-assist hinges provide strength, durability, and safety in your design. For more information on our heavy-duty hinge lineup, check out the free resource below:

Taking the Weight off Your Shoulders | Vectis® Spring-Assist Hinge Applications:

It’s easy to see the benefits of heavy-duty spring-loaded hinges. Best of all, they have applications in many industries:

  • Healthcare
  • Entertainment
  • Hospitality
  • Manufacturing
  • Aerospace
  • Agriculture
  • Marine
  • Military/armored vehicles

Today’s spring-assist hinges provide more enhanced mechanical strength and durability. Spring-loaded hinges are perfect for high heat applications, like BBQ grills and drum smoker lids, making cooking more convenient. Spring-assist hinges also work well in subzero temperatures, like in cryogenic freezers

In the manufacturing industry, heavy-duty spring-assist hinges allow a specific amount of rotational force to open or close a lid or cover, assuring user safety. 

Since gas springs are prone to failures and contaminating leaks, many engineers are turning to mechanical spring-assisted hinge designs to improve workplace safety.

While there are many Band-Aid solutions on the market, Vectis® technology spring-assist hinges can stand up long-term to extreme conditions, from a kiln to a cryo freezer. We thrive when we work with customers who want to push the boundaries of heavy-duty lid and door design.
