What are Shaker Plates?

Shaker Plates, also known as Wheel Play Detectors, are powered devices that are used during MOT tests to assess a vehicle’s steering and suspension. They are an important tool in maintaining the reliability and safety of vehicles as they detect any excessive movement in the suspension and steering systems.

How do Shaker Plates work?

The vehicle drives onto the testing area with the wheels on the Shaker Plates. Suspension is analysed through lateral movements of the plates, and steering is analysed through rotations of the plates.

Types of Shaker Plates

There are 2 popular options for Shaker Plates:
  • Play Detector. This uses a single plate which is placed on one side of the vehicle, which allows for one worker to observe and measure the lateral and rotational movement of a wheel.
  • In-ground Shaker Plate. These are popular for garages that use inspection pits, as the plates are installed on either side of the pit. This gives the workers the under-vehicle access to see the movements in the wheels and the steering joints.

Converting TPTL (Two person testing lane) into OPTL (One person testing lane) using Shaker Plates

The use of a shaker plate can also reduce the need for a second person to manoeuvre the wheels for inspection and testing of wheel and suspension components, thus this can be used to turn a Two Person Test Lane into a One Person Test Lane (OPTL) for MOT testing.
