KCH-2059 it's portable single side slip tester, to turn the wheelbarrow, it is leaned to one side and the wheel barrow rolls around in the direction of the lean. Just like when riding a motorcycle, the motorcycle is leaned into a corner, and the rolling action of the change in profile of the tyre, directs the motorcycle around the corner. The curved shape of the tyre means that the section in contact with the ground has a smaller radius than when upright, causing the tyre to roll in the direction of the lean, hence turning the wheelbarrow, or motorcycle. This is a similar action caused by Camber on a motor vehicle.
If there has been no change to the wheel alignment through accident or damage, then performing a Side Slip test and adjustment is generally all that is necessary to correct accelerated tyre wear.
Zero side slip is the most acceptable measurement. A maximum side slip of 5 metres per kilometre (or 5 millimetres per metre) is generally accepted globally as an Industry standard. Some Side Slip testers identify the slippage as Millimetres per Metre, instead of Metres per Kilometre.
The misconception that Side Slip is the same as Toe In/Out is quite common, as the specifications can appear similar
