A case study proposing investigation and measures for the loosening of embedded bolts used to secure tire wheels.
We would like to introduce a case where we proposed the identification of the cause of loosening and permanent countermeasures through hypothesis establishment and dimensional inspection using an image measurement device for an industrial vehicle manufacturer. There was an issue where the embedded bolts used to secure the forklift tire wheels would fall off after delivery to the customer. We shared knowledge regarding the embedded bolts and conducted dimensional measurements of the threaded parts using the image measurement device. We proposed clearly stating tolerances on the drawings to ensure accurate communication of information among design, quality control, procurement, and suppliers. [Overview of the Issue] ■ The embedded bolts used to secure the forklift tire wheels fall off after delivery to the customer. ■ If they fall off during operation, it could lead to a serious accident, so it must be resolved urgently. *For more details, please refer to the related links or feel free to contact us.
