Customer Industry/Description of Problem

  • Grinding and polishing of 34 lb. customer part
  • Most challenging operation outsourced due severity of ergonomic problems

Known Data Regarding the Application

  • Multiple propellers held up to grinder/polisher – part to tool
  • Freedom of motion is critical given that a good polish is more ‘art than science’

Solutions Considered

  • Various solutions considered to try to ‘hold’ the part.
  • Final solution incorporated specialized gimbal to hold multiple configs.

Reasons for Final Solution Selection

  • Gave the operator the same freedom of motion as manual operation

Customer Benefits (ROI)

  • Verified injury data from this application, zeroG® will 100% eliminate
  • Improved employee morale

Drilling Example

 

Customer Industry/Description of Problem

  • Manufacturing location for aircraft
  • Area considered is flap hinge on tail section

Known Data Regarding the Application

  • Low repetition, but very awkward reach needed with heavy tool
  • Three different Quackenbush in-line drills used with different size bits (quick change req’d.)

Solutions Considered

  • Ring gimbal with removable inner race. Inner race stays with each tool.
  • Special quick release outer ring allows for quick tool change.

Reasons for Final Solution Selection

  • Simplified tool change and easier handling

Customer Benefits (ROI)

  • Verified injury data from this application, zeroG® 100% eliminated
  • Improved employee morale

Riveting Example

 

Riveting Example

 

Customer Industry/Description of Problem

  • Aircraft production facility
  • Significant injury problems associated with use of heavy rivet gun

Known Data Regarding the Application

  • 28 lb. Rivet Gun used overhead and held a shoulder level for applying rivet to fuselage
  • Work area includes long sections of the fuselage and elevated areas

Solutions Considered

  • Original offer to mount the arm on a vertical slide rail
  • Customer decided to purchase arms along with gimbals and 2-axis mount and make their own slide rail system

Reasons for Final Solution Selection

  • Large ring gimbal provided the right size and range of motion for the various angles at which rivets were applied

Customer Benefits (ROI)

  • Injury avoidance
  • Reduced downtime due to exhaustion
  • Improved quality due to more precision in guidance of the tool
 
 

Heavy Equipment Manufacturing

 

Torque Tool Example

 

Torque Tool Example

 

Customer Industry/Description of Problem

  • Heavy equipment manufacturer
  • Mounting "stirrup" bracket underneath transmission with 4 4" long bolts

Known Data Regarding the Application

  • 26 pound Uryu inline pulse tool in vertical orientation

Solutions Considered

  • Single link arm with static link due to limited vertical travel required
  • Ring gimbal with special mounting brackets to grab the tool

Reasons for Final Solution Selection

  • Cost, static location and limited tool range of motion requirement

Customer Benefits (ROI)

  • Injury risk avoidance
