Meter Engineers - Model Nitro Balance -Nitro Balance Gas Spring Canisters for Load Arms

SHARE
The newly designed Nitro Balance™ spring assist canisters by Meter Engineers represent an advancement in load arm counterbalance technology. These canisters use heavy-duty gas springs designed in a parallel setup, providing an optimal low spring rate necessary for operators to effortlessly position load arms. Unlike traditional coil or torsional springs that require excess force to maintain equilibrium, the Nitro Balance™ canisters are tailored with precise nitrogen pressure to suit specific loading arm requirements, ensuring a smooth and efficient operation. This customization is supported by Meter Engineers' engineering team, offering bespoke sizing for varied industrial needs. The gas springs provide sufficient force to sustain the arm's mass throughout its range of motion, optimizing performance and reducing operator strain. The innovation promises a cost-effective, reliable solution for enhancing the operation of load arms in various applications with a focus on boosting accuracy and dependability in the field.

Meter Engineers’ new Nitro Balance™ spring assist canisters are the most versatile and dependable load arm counterbalances on the market today. Forget your worn-out coil or torsional spring canisters. Nitro Balance™ canisters utilize heavy-duty gas springs arranged in a parallel configuration. These gas springs provide a much lower spring rate than can be achieved with any other style of spring while still providing a high enough force to hold the entire mass of the arm. Load arms need a canister with a low spring rate so that the operator can effortlessly move the arm to any position throughout the entire range of travel. The biggest issue with coil or torsional canisters is that the force in the canister increases much faster than what the arm needs to be held in equilibrium, so the operator must fight the canister to move the arm when instead the canister should be doing all the work.

 

Nitro Balance™ gas springs are filled with a specified nitrogen pressure from the factory to exactly match the force needed for your loading arms. This is a very cost-effective way to get a completely custom spring canister that is perfectly tuned for your arms. Meter Engineers engineering department will help size a custom canister to fit all your needs.

 
  • Load arms need a low spring rate to be in equilibrium. At all locations through the travel, nitrogen gas springs can provide a much closer rate to the required arm rate than a coil or torsional spring can achieve.
  • Since the rate of a nitrogen spring is based on the canister volume, the canister volume can be sized to match the rate needed by the arm. A mechanical spring rate is based on the material properties and has binding limits, unlike changing the volume of the gas.
  • Standard spring assists use mechanical springs that must be compressed to get to their installed length for the needed arm equilibrium force, where the gas springs installed length is also their free length, and the vital force is already set into the gas spring. This makes the assembly and maintenance much easier and safer.
  • Once the mechanical spring is in the canister, a considerable amount of energy is stored, even at the installed height. But with a gas spring, all energy is stored within the gas spring and not on the canister. Meaning when the gas spring returns to the installed height, the canister retains no energy, allowing the canister to be greatly simplified and much smaller than a traditional canister.
  • Since the gas springs have their canister with threads, they are easily attached for solid and safe mounting, unlike a spring usually sandwiched inside the canister.
  • The gas springs can be made to any diameter and length to accommodate the force, rate, and stroke needed to fit each individual load arm application.
