To welcome riders for the busy 2016 summer season, an American amusement park roller coaster required alignment. At the end of last season the coaster’s driving assembly, the mechanism that pulls cars up the hill at the start of the ride, experienced a bearing failure. Damage to the gearbox was significant. Following the manufacturer’s repair and overhaul of the damaged parts, the gearbox had to be re-installed. Proper alignment was crucial. The park operators called in PRUFTECHNIK to make sure this alignment was done right.
