The diameter of the top plate is also an important factor. With a large diameter there will be a leverage effect. This means you will need a larger revolving platform when you’re using a larger presentation disc.

What exactly does the leverage effect entail? A good example to illustrate the effect is lifting a bucket full of water. You’ll probably find it easy to lift a bucket of ten kilos. But when you’re asked to hold the same bucket with your arm extended -with the bucket at about half a metre from your body- it suddenly becomes almost impossible to hold the bucket in the air. This leverage principle plays an important role with turntables, when carrying a load that’s not in the middle or is not evenly distributed.

Our webshop turntables are sold without top plate. This allows you to screw on the presentation platform of your choice yourself. This is very easy to do. If so desired, you can also order a presentation disc with your turntable; Pre-Motion offers them in various diameters and materials.

Revolving platforms with a diameter of 150 cm and up are sold with a sturdy top surface of laminated wood, which you may finish in any manner you choose.

However, for the MAX 100 - 200 - 300 kg turntable, you are able to lower the speed of rotation continuously up to -40% by purchasing speed control with your turntable.

Exception: for the MAX 500 - 750 kg turntable you are, however, able to make the turntable rotate in both directions by selecting the option for clockwise and counter clockwise rotation.

Our web shop offers presentation discs of Ø 30 - 80 cm. Please note that these presentation discs are too large for the two smallest turntables in our web shop: the MAX 4 kg turntable and the MAX 5 kg turntable. You are, however, able to mount your own presentation disc to one of those small turntables (< Ø 30 cm).

Please note: the turntable is not covered under warranty after you have opened up the turntable yourself.
