Lift Chain "Stretch" Monitor
Create a device or method of actively measuring wear in lift chains
Objectives
Develop and build a functional prototype to the following requirements:
- Measure chain “stretch” (the cause of “stretch” is actually wear) within +/- 5% of actual
- Cost less than $10 or less at production quantity of 15,000/yr
- Be robust enough to survive abrasive (high chain wear) applications
- Outputs an analog (5v) or digital signal (CAN or other serial protocol signal)
Project requires an end of project presentation and demonstration onsite at Hyster-Yale Group in Fairview, OR
Motivations
Lift chains are in constant use for raising and lowering loads in a lift truck (forklift) mast and should be replaced when they reach a certain amount of wear. The rate of wear is dependent on environment and maintenance, so it’s difficult to state a specific time interval for replacement. Being able to easily detect this wear and communicate it to the operator via the display would help ensure chains are replaced at the appropriate service interval for the customer application.
