In the fall of 2013, PIRTEK Kent Owner Gabe Gilliam received a call from the Washington State Fair in Puyallup, Wash., a customer of the company's. This year the Washington State Fair added a new attraction, a looping inversion roller coaster, the Rainier Rush, which needed service to ensure maximum performance at the September 2013 debut. The only model of this ride in the United States, it will take riders more than 60 ft. (18 m) in the air before catapulting downhill around wild loops, along wavy tracks and bendy curves.
Mobile Sales and Service Technician Ray Rios arrived on site and immediately put his fall protection equipment on. First, he inspected the equipment and prepared a list of necessary parts. Rios had everything he needed in his Mobile Sales and Service Unit to complete the job.
Rios then installed new hydraulic motors on the track just before the coaster cars would navigate the upside-down loop. Rios plumbed three motor pumps on this section to speed up the trains. He also installed a new electric control valve on a tank and plumbed it into the internal manifold with hoses.
Rios measured, cut and installed hose assemblies in various lengths and sizes. There were eight PFMU25 hose assemblies with JIC fittings and ferrules and three 115 ft. (35 m) PFMU25 hose assemblies with JIC and NPTF fittings and ferrules. A variety of adapters were used including JIC and NPTF elbows. Rios also provided a new custom mounting plate, check valves and gauges.
