Not being a salesman I do not have access to the technical data that all OEM reps would be able to supply you. From a service perspective I can tell you that it is crucial to pay attention to floor flatness especialy when installing wire guidance in VNA aplications. We have seen customers spend hundreds of thousands of dollars on regrinding floors because at full speed the operator up forklifts were smashing into the racking at 40 feet in the air due to poor floor conditins. After the grinding we still had to keep the speeds under 5 miles per hour to avoid guidance problems magnified by high speed wobbles. Write back if I can assist any more.
