A turn table trolley is a base that can be of any size, shape or description which, which is supported by wheels. The front wheels and axle are a separate piece which has a fitted to a plate, that plate is then joined to a plate fixed directly to the base/chassis of the trolley by a pivoting fixing, this can be a bolt or pin. Between the plates, can either be bearings or the plates can be greased to reduce the amount of friction when steering the unit. Attached to the front axle is a handle, when you turn the handle left or right the wheels then follow the direction in which the handle is directed therefore steering the trolley.

The turntable trolley historically was the main style of trolley used, until the castor came into existence, and then developed into what is now the most common type of steering mechanism on a handling trolley, the turn table trolley is still heavily used in industry today especially where the loads being moved are heavy.
So why when a turntable trolley is so much bulkier and more expensive that an standard flatbed trolley or platform truck would you want a turntable style over the basic trolley type.Turntable trolleys can be fitted with many differing types of wheel. Solid wheels, a hard rubber bonded tyre, fitted onto either a plastic, steel or cast iron centre. Or a pneumatic tyre which is as you would find on your bike, a rubber tyre mounted again on either a plastic or steel centre, fitted with a valve so that air can inflate the tyre to enable a more cushioned ride. Or finally these trolleys are now being mounted on runflat tyres, some time call puncture proof tyres, green tyres, cellular foam tyres or polyurethane tyres.
