Grinding is a tough job. Let the Zero G do the heavy lifting.

The use of heavy hand-held grinders is a typical requirement of most casting, forging and metal fabrication activities. It is cumbersome and tiring work which places considerable stress on the user. As a result, grinding is often considered to be one of the least desirable work assignments and is typically an area with a significant prevalence of injury.

The annual ROI for Zero G ergonomic tool arm grinding customers often ranges from 250 to 500%.

By transforming even heavy grinders into a fraction of their actual weight, Zero G ergonomic tool arms can:

  1. Dramatically increase productivity
    • Operators can use a grinder longer without experiencing fatigue (because even heavy grinders weigh essentially nothing).
    • The Zero G lets you use heavier, more powerful grinders safely, reducing cycle time.
    • Many users report labor reduction or productivity improvements of up to 50% through the use of the Zero G ergonomic tool arm.
  2. Reduce or eliminate many common grinding-related injuries.
    • Not surprisingly, lifting even a 6-pound grinder for several hours a day puts the body under tremendous strain.
    • For a typical injury, direct medical costs alone can exceed US$20,000. When indirect costs such as lost time and retraining are included, costs can easily exceed US$40,000-80,000 for a single injury.
  3. Reduce tool damage and grinding disc usage.
    • With Zero G, cables and hoses are festooned along the arm to prevent damage. Also, since tools are no longer dropped when not in use, tool repair costs are reduced.
    • Since tools can be held in an optimal position, grinding disc usage can be reduced – often by 30-40% – since more of the pad can be used with proper pressure.
    • Combining these effects, customers can see costs savings of US$500 to US$1,000 per year or more in material savings alone.
  4. Improve Employee Satisfaction. Reduce Absenteeism.
    • Many customers using Zero G ergonomic arm systems have experienced reductions in absenteeism (more than 50% in some cases) while also being able to return restricted duty employees to work.
  5. Improves quality.
    • A grinding operator can grind much more precisely when he only has to support a fraction of the grinder’s actual weight.

Zero G is simply a better way to grind and a new best practice in some of the world’s top manufacturers.
