The SPID 20000 electronic play detector is used to check wear-related bearing play on truck chassis parts (axle knuckle bolts, bushings, ball joints, steering parts, etc.).
It consists of 2 hydraulically moved plates, which can be lowered into the workshop floor, with a maximum axle load of 20 t and a movement of +/- 50 mm on each side. On these the vehicle wheels can be moved directly on the vehicle in longitudinal and transverse direction in order to locate existing play. The different directions of movement are automatically controlled by wireless operation.
This allows you a simple and reliable diagnosis of the axis joints.
