POSITAL Absolute Encoders Automate Goodyear Airship Facilities
The Goodyear Tire & Rubber Company recently unveiled major new facilities at its Airship Operations base in Carson, USA.
The new facilities include a new hangar for the Goodyear Blimp Wingfoot Two, which arrived in Southern California at the end of 2017.
The site for the new hangar is a closed landfill site which means that only shallow grading of the site is possible. This shallow grading limits the weight that can be carried by the slab and prevents the construction of a traditional hanger. Instead, the hangar is built out of 73 miles of partially translucent polyester fabric and is almost nine-stories tall and longer than a football pitch.
Additionally, due to the explosive risk of methane released from the old landfill grounds, state sanctioned remedial plans for the site called for electrical and electronic equipment to be certified for use in potentially explosive gaseous environments.
The manufacturer of the incredible inflatable hangar is a UK based technology company specialising in inflatable buildings. They approached Emolice to help with the design and integration of the position control system used to raise and lower the hangdoor.
The final solution used ATEX certified Profibus absolute rotary encoders from POSITAL to control the position of motors that open and close the ‘eyelid’ door via a proprietary PLC.
Emolice led the mechanical integration of the encoders with the chosen motors and ensured that the encoders were specified, manufactured and delivered within 2 weeks of the start of the project. The new hangar was successfully installed in mid December 2017 and is now in full use.
