What is zeroG®?

Iso Elastic (constant) spring driven “lift” throughout range of travel.

zeroG® is unpowered and controlled entirely by the operator.  In essence, zeroG® makes tools and parts weightless by offering a second set of fingers, wrists, arms, and legs.

Fingers Tool Interface

The Tool Interface is much like our own fingers, providing a sturdy grip on the tool.

Why choose zeroG®?

Value Proposition

Boost Productivity Reduce Injuries Improve QualityBoost Productivity Reduce Injuries Improve QualityInjuries due to overexertion and repetitive stress 

impose heavy costs on companies and their employees; zeroG® technology can often reduce injuries to zero for tasks involving use of tools 

and maneuvering parts

Quality can be improved by reduced error rates from fatigue associated with repetitive motion tasks, along with greater precision with heavy tools.

zeroG dramatically boosts productivity by letting you work faster and longer 

without fatigue or strain

Competitive Advantageand maneuvering parts.

Proven• Already in use by many of the top manufacturing companies in the world, with numerous installations for a variety of challenging applications

Performance• Unmatched freedom of motion allows users to maneuver as if there were no lift assist provided.• zeroG® systems deliver a dramatic increase in productivity due to applications.

Cost Effective• Standard components allow for commonality of engineering and design standards vs. custom solutions that are expensive, cumbersome and not repeatable• Lower total cost of ownership per installed system when compared to 

h l i

• zeroG systems deliver a dramatic increase in productivity due to operators being able to work longer with reduced fatigue. • Powered arms (pneumatic, hydraulic, actuated) offer limited range of motion and introduce reaction delay

Flexibility • Modular, flexible design allows components to be used in many 

other solutions.• Lets users rely on existing skills and experience with little or no additional training required.

Virtually No Maintenance Required• Simplicity of design allows zeroG® to have few moving parts and minimal maintenance requirements.

different applications and redeployed as needed.Energy Efficient• Requires no compressed air, hydraulic or electrical power. Operation is 100% mechanical, saving power costs and eliminating the need for additional cabling/hoses.

Small Footprint

qSmall Footprint• zeroG® systems can be mounted from virtually any component or location. Other systems require floor or overhead mounting.
